Air pollution dispersion has become the focus of environmental conservationists and governmental environmental protection agencies (local, state, province and national) of many countries (which have adopted and used much of the terminology of this field in their laws and regulations) regarding air pollution control. The more advanced models use some form of Monin-Obukhov similarity theory. Depending on the pollutant analyzed and its permissible values, 24-h, 1-h, or 8-h rolling averaging was used. The top of the inversion helps to indicate the mixing height, which is essentially the level below which the air will readily mix. It is performed with computer programs that solve the mathematical equations and algorithms which simulate the pollutant dispersion. Because, meteorological measurements are generally conducted at standard 10 m altitude. It has been observed and confirmed that the values of temperature, humidity, and wind speed for individual months are comparable to those found in the Atlas of Climate in the Wielkopolska Region (Farat 2004). Air Pollution Meteorology and Dispersion. Now imagine that parcel of air representing air pollution it is effectively trapped near the surface during a surface temperature inversion, and is not able to readily disperse vertically. The nearest human settlements are located in the following distances: 0.6kmPiotrkowice village (532 inhabitants), 1.5kmWygoda village (270 inhabitants), 2.1kmNiedwiady Due village (163 inhabitants), and 3.1kmPwiosek Stary village (263 inhabitants) as well as about 3.5kmtown of lesin (about 3200 inhabitants) and 4.2kmtown of Liche (about 1500 inhabitants). The natural resource of the region is primarily lignite, whose mining has been taking place in the northern part of the region for over 70years and is used as fuel in power plants Ptnw I, Ptnw II, and Konin, which are parts of the Ptnw-Adamw-Konin Power Plant ComplexZE PAK S.A. To illustrate the hypothetical scale of environmental impact of the plants, the average amount of combusted lignite, biomass, fuel oil, and the amount of electricity and heat produced in the analyzed period is presented in Tables1 and and2.2. On the other hand, the permissible level for nitrogen dioxide is the instantaneous (1h) value of 200g/m3, so Fig. When the land is dry and winds are strong enough (often as a strong, dry cold front advances), large amounts of blowing dust can be generated, and the finer the dust, the longer it will take to settle out of the air mass. The following pollutants have been measured: particulate matter PM10 (in concentrations ranging from 5.0g/m3 to 250mg/m3), sulfur dioxide (0 to 500ppb), carbon monoxide (0 to 50ppm), nitrogen oxide (0 to 500ppb), nitrogen dioxide (0 to 500ppb), nitrogen oxides NOx, as the sum of NO and NO2 (0 to 500ppb), and ozone (0 to 500ppb). In areas near and immediately downwind of the source region of the dust, its not uncommon for daily fine particle pollution AQIs to reach Code Red, or even Code Purple levels. This type of event happens in other desert locations as well, such as Arizona and New Mexico. Since the emitted pollutants are subjected to both dispersion and advection in the air, the analysis of such phenomena should take into account both the wind speed and direction, vertical movements of air due to thermodynamic equilibrium of the atmosphere, and local turbulences caused by altitude contrasts in the land cover. Concerning the pollutant dispersion modeled at noon, it can be said that with the full development of the boundary layer and the prevailing synoptic circulation in almost the entire basin, air pollutants released from the stacks moved to the west ( Fig. . The aim of air pollution modelling is the estimation of outdoor pollutant concentrations caused, for instance, by industrial production processes, accidental releases or traffic. Thankfully, as the lower atmosphere continues to be warmed by the sun, an overnight temperature inversion will erode and mixing heights increase and allow for better mixing of the air. Vallero, D. (2014). [10] Such that, for flows where the cloud of pollutant is smaller than the largest eddies present, there will be mixing. The appearance of these conditions results in different levels of air pollution characteristic for a given period. Based on the above mentioned factors the atmospheric condition has been classified into different stability classes. The Saharan Desert region was once under water, and the sand is very fine and rich in nutrients and minerals from ancient decomposed marine life. Politechniki 6, 90-924 Lodz, Poland, 2Faculty of Process and Environmental Engineering, Lodz University of Technology, Wolczanska 175, 90-924 Lodz, Poland, 3Department of Environmental Protection of Ptnw-Adamw-Konin Power Complex S.A, Kazimierska 45, 62-510 Konin, Poland, Location of the monitoring station Piotrkowice (P) in relation to the Ptnw Power Plants I, II (1), and Konin Power Plant (2) (https://www.google.pl/maps/@52.3539092,18.3324928,13.64z?hl=pl), Production of electricity and heatannual values from 2009 to 2015 (ZE PAK S.A. corporate materials), Emission of pollutantsannual values from 2009 to 2015 (ZE PAK S.A. corporate materials), PM10 concentration depending on air temperature, humidity, and wind speed in particular months of the year, Sulfur dioxide concentration depending on air temperature, humidity, and wind speed in particular months of the year, Nitrogen dioxide concentration depending on air temperature, humidity, and wind speed in particular months of the year, Carbon monoxide concentration depending on air temperature, humidity, and wind speed in particular months of the year, Ozone concentration depending on air temperature, humidity, and wind speed in particular months of the year, Percentage of particular wind directions from the years 20092015, Wind rose for analyzed area (mean values for years 20092015), Average temperature [C] and humidity [%] in months and years 20092015, Dispersion of atmospheric air pollution in summer and winter season. Air pollution (2nd edn). (1936). The London household survey has shown that people travel and are exposed to air pollutants differently. The following outline is presented as an overview and topical guide to air pollution dispersion:; Air pollution dispersion - distribution of air pollution into the atmosphere. In addition to smoke, dust can reach long distances as well. INTRODUCTION TO AIR POLLUTION 1.1 The Air Pollution Problem 1.2 Sources of Air Pollution 1.3 Air Pollutants 1.4 Effects of Air Pollution 1.5 Regulatory Control of Air Pollution 2. Based on emissions and meteorological inputs, a dispersion model can be used to predict concentrations at selected downwind receptor locations. An exception in this case is ozone whose specific formation in the lowest part of the Earths atmosphere causes high concentrations that appear in the periods of maximum insolation, longer days, and higher air temperatures, while lowwhen activity of the sun is lower, days are shorter, and air temperature is lower (Je 2009). Using the full equation which describes these features is called Eulerian dispersion modelling (Pielke 1984). When we think of air pollution today, we think of cities like Beijing. Air quality in both Poland and other countries of the world depends on the amount of pollutant emissions, the intensity and type of physicochemical changes taking place in the atmosphere, and the large-scale movements of polluted air masses. Chapter 1 The Nature of Chemical Process. 2016; Vallero 2014). You may have noticed this phenomenon if you are ever outside in the early morning of January 1st or July 5th following New Years Eve/July 4th firework displays sometimes the air seems hazy/smokey, and its usually thanks in part to a low-level temperature inversion trapping the celebratory smoke. https://doi.org/10.1021/es3011282. 4 shows the averages of the maximum instantaneous values from individual months in the seven-year period analyzed. 1.2 Formulation Plumes are of considerable importance in the atmospheric dispersion modelling of air pollution. The dispersion models are used to estimate the downwind ambient concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases. As a result of the dispersion of pollutants emitted to the air, the determined concentrations of pollutants are formed on the Earths surface, which are related to the limit values specified in national and international law (Colls 2002). For analysis, the results of measurements of air pollution and meteorological data recorded by the Piotrkowice measuring station in the seven-year period (20092015) were selected. The functionality is limited to basic scrolling. The contribution of outdoor air pollution sources to premature mortality on a global scale. Of course, in order to be consistent with the results obtained for pollutants, meteorological data were analyzed for the same time period as for air pollutants. Effect of urban traffic on the immision of carbon dioxide in the university campus. It was mounted in the meteorological radiation shield, while wind direction and wind speed measurements were carried out using a WindSonic ultrasonic sensor from GILL Instruments installed at the top of a 12-m meteorological mast. The dispersion modeling is based on the physics . Since the dust is so fine it is easily disturbed by winds and in this region blowing dust events can happen a couple times a year. and Pearson, J.L. The right side of each sounding shows how the wind speed and direction change with height. Bosanquet, C.H. Measurement of ozone concentration was provided by optical method at 254nm (UV) using Thermo 49i analyzer. All measurements of pollutants are made by analyzers whose measurement methods are in accordance with the reference methods specified in Annex VI of the CAFE Directive. Figure Figure22 shows averaged daily concentrations of PM10 for both individual months and the average for the years 20092015. 3 shows the average sulfur dioxide concentration for each month and the average for 20092015. Design and Integration 1. Assuming an elevated source, Equation 4-8 simplifies to: 22 22 environmental lapse rate is greater than adiabatic lapse rate ; environmental lapse rate is less than adiabatic lapse rate Gkseries.com is a premier website to provide complete solution for online preparation of different competitive exams like UPSC, SBI PO, SBI clerical, PCS, IPS, IAS, IBPS PO, IBPS Clerical exam etc. Sources, by shape there are four basic shapes which an emission source may have. Gaussian or Normal distribution . If you guessed the one on the left, you are correct! The amount of dispersion is directly related to the stability of the air, or how much vertical air movement is taking place. Learn more on about us page. Download scientific diagram | Mean concentrations in the horizontal plane at z/H=0.5\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym . What are the air pollutants responsible for acid rain within and downwind areas of major industrial emissions? Atlas klimatu wojewdztwa wielkopolskiego. The ePub format is best viewed in the iBooks reader. The sounding on the left shows an atmosphere readily cooling with height, and moderate winds from the surface to the upper atmosphere (albeit with an inversion around 750mb). Figures7, ,88 and and99 show the analysis of meteorological conditions carried out to determine the direction of incoming air pollutants or to predict them. The mapping module produces a concentration at each census tract. Pollution dispersion follows a distribution . Prevailing easterly winds carry the dust across the ocean, reaching North and South America. Acknowledgements xv. Atlas klimatu wojewdztwa wielkopolskiego. https://doi.org/10.1515/eces-2015-0030. This happens on a larger scale in a city like Los Angeles that is surrounded by mountains on three sides. 2012; Lelieveld et al. Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the . 4) Carrying out research in air pollution control methods. The wind barbs point to where the wind is coming from, and the longer the barb on the end, the swifter the winds. Environmental Science. & other graduate and post-graduate exams. The objective of this research is to study the dispersion of air pollutants and mitigate the impact of pollutants on the populations living around the power plant. London: SPON PRESS, Taylor & Francis Group. Measurements suggest a rapid decay of pollutants from roadside into parks. already built in. Faraday Soc., 32:1249. It should be borne in mind at the same time that low-emission sources emit pollutants primarily during the heating season, and that remote systems do it with varying intensity throughout the entire calendar year (Cichowicz and Wielgosiski 2015a, b; Lin et al. He categorized the atmospheric turbulence into six stability classes named A, B, C, D, E and F with class A being the most unstable or most turbulent class, and class F the most stable or least turbulent class. Received 2017 Jun 1; Accepted 2017 Oct 20. We are experimenting with display styles that make it easier to read articles in PMC. Its aim is to improve air quality and protect against the harmful effects of pollution on the environment. Where air pollution ends upbe it a locally generated plume of ozone or . For example, consider a small controlled burn that emits smoke particles for a couple of hours. Farat, R. (2004). It was mounted in the meteorological radiation shield, while wind direction and wind speed measurements were carried out using a WindSonic ultrasonic sensor from GILL Instruments installed at the top of a 12-m meteorological mast. pollutants back into the atmosphere Rfl i diReflection at some distance x is mathematically equivalent to having a mii fhirror image of the source at -H There are three primary types of air pollution emission plumes: There are five types of air pollution dispersion models, as well as some hybrids of the five types:[1]. Here in the United States, West Texas is home to the Permian Basin and parts of the Chihuahuan Desert. Pembangkit Listrik Tenaga Uap (PLTU) Batubara Banten 3 Lontar (3 unit x 315MW) berlokasi di Kabupaten Tangerang, merupakan bagian dari proyek percepatan kelistrikan 10.000 MW di Pulau Jawa. The study aimed to explain variability in outdoor concentrations of six traffic-related air pollutants (nitrogen oxides, nitrogen dioxide, ultrafine particles, black carbon, fine particles, and ozone) at two sites near a heavily traveled freeway (140,000-145,000 vehicles per day) and a busy urban intersection (about 1,000 vehicles per day; Statement Figure). It means that we are expecting limited dispersion of air pollution, or to put it another wayif theres some air pollution around it wont be going very far! Dispersion modeling uses mathematical formulations to characterize the atmospheric processes that disperse a pollutant emitted by a source. The following pollutants have been measured: particulate matter PM10 (in concentrations ranging from 5.0 g/m 3 to 250 mg/m 3 ), sulfur dioxide (0 to 500 ppb), carbon monoxide (0 to 50 ppm), nitrogen oxide (0 to 500 ppb), nitrogen dioxide (0 to 500 ppb), nitrogen oxides NO x, as the sum of NO and NO 2 (0 to 500 ppb), and ozone (0 to 500 ppb). PM10 concentration depending on air temperature, humidity, and wind speed in particular months of the year, Sulfur dioxide concentration depending on air temperature, humidity, and wind speed in particular months of the year, Nitrogen dioxide concentration depending on air temperature, humidity, and wind speed in particular months of the year, Carbon monoxide concentration depending on air temperature, humidity, and wind speed in particular months of the year. 5), in which the recorded concentrations were referred to a permissible level of 10,000g/m3 and defined as an 8-h rolling average. This is also why there will occasionally be a fire tornado or fire whirl in large firesupwards air currents lift the burning flames, resulting in a fire whirl, which is a good way to visualize the phenomenon of warm air rising. Dispersion of Pollutants In the Atmosphere "Transport and dilution of pollutants by air motions goes on constantly; and all of humanity, particularly that large segment . In environmental science, air pollution dispersion is the distribution of air pollution into the atmosphere. Dilution occurs owing to mixing into the air. An additional Stack Height Assessment was also undertaken to provide further information on the air quality impact of the plant with stack heights of 30 m and above, in the context of IFC Environmental, Health and Safety Guidelines for Thermal Power Plants, which had been revised since the issue of the 2008 Addendum (Scott Wilson, November 2009). Dispersion refers to what happens to the pollution during and after its introduction; understanding this may help in identifying and controlling it. before it has had a chance to undergo much dispersion * air quality at the ground near stack is actually much worse than in case of the stable atmosphere. 2002). Horizontal Dispersion. As a result of the dispersion of pollutants emitted to the air, the determined concentrations of pollutants are formed on the Earths surface, which are related to the limit values specified in national and international law (Colls 2002). Environ Monit Assess. dispersion of pollutants we must be able to assess how wind direction changes with altitude. Table 1: Factors affecting the dispersion of the pollutants Source characteristics Meteorological Conditions Emission rate of pollutant Wind velocity Stack height Wind direction Subject - GATE Environmental EngineeringVideo Name - Dispersion of Air Pollutants in the AtmosphereChapter - Air PollutionFaculty - Prof. Mukesh RaiWatch the. PM10 particulate matter measurement was carried out using a TEOM 1400a type analyzer based on a gas sample filtration system and automatic mass measurement. Air Pollution Meteorology and Dispersion provides a concise yet thorough review of the basic theories, models, experiments, and observations of pollutant dispersal in the atmosphere. Quantification of fossil fuel CO2 emissions on the building/street scale for a large U.S. City. Nitrogen oxides (NO and NO2) are measured by a Thermo 42i chemiluminescent analyzer, and the carbon monoxide concentration is measured using an Thermo 48i IR spectrometer. 2017 Nov 4;189 (12):605. . On the other hand, in summer time, the opposite situation occurred, namely, when temperature was high and wind speed and humidity lower, air pollution was also reduced. A comparison of correlation-length estimation methods for the objective analysis of surface pollutants at Environment and Climate Change Canada. 1.1 Chemical Products 1. Mechanical turbulence is the induced-eddy structure of the atmosphere due to the roughness of the surface over which the air is passing. The air monitoring station is located in a 2.53.0m container 2.5m high, which is resistant to external weather conditions. Mnard, R., Deshaies-Jacques, M., & Gasset, N. (2016). The problem of air quality was noted by the World Health Organization (WHO), which estimated in 2012 that about 7 million deaths were associated with living in the areas with polluted air. Transport is movement caused by a time-averaged wind flow. The surrounding area is primarily arable land and meadows. The dispersion of pollutants in atmosphere is maximum when . Describe radiational inversion formation present note the role of wind in dispersing the pollutants is presented. Have you ever heard the phrase warm air rises? This is something to keep in mind when thinking about vertical dispersion. Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, and the natural or built environment. The dispersion rates of pollutants are governed by the strength of wind and the nature of the turbulent field.2 A number of authors (R. R. Dickson,3 N. E. Law-rence4) pointed out that the maximum concentration of pollutants is observed under calm conditions or at very low Bibliography of atmospheric dispersion modeling, AP 42 Compilation of Air Pollutant Emission Factors, Useful conversions and formulas for air dispersion modeling, Air Pollution Dispersion: Ventilation Factor, DEGADIS Technical Manual and User's Guide, UCRL-MA-105607, User's Manual For Slab: An Atmospheric Dispersion Model For Denser-Than-Air Releases, 10.1175/1520-0450(1973)012<0547:sdd>2.0.co;2, "AERMOD:Description of Model Formulation", Air pollution dispersion modeling terminology, https://en.wikipedia.org/w/index.php?title=Outline_of_air_pollution_dispersion&oldid=1119379650, Articles with dead external links from July 2019, Articles with unsourced statements from December 2011, Articles with disputed statements from December 2011, Creative Commons Attribution-ShareAlike License 3.0, The DEGADIS model developed by Dr. Jerry Havens and Dr. Tom Spicer at the, Types of air pollutant emission sources named for their characteristics. 2016; Vallero 2014). Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Sulfur dioxide concentrations were measured using an automatic Thermo 43i UV spectrometer. The analysis of air pollution in terms of seasonality can explicitly confirm the presence of elevated levels in winter months and during the heating season and low in summer months and during the summer season. Wind speed and direction can be useful measurements in a variety of air quality-related activities. Urban areas have been established as one of the main contributors to air pollution, and, as such, urban air quality is the subject of an increasing volume of research. Air Pollution MCQ - Environmental Engineering 31. Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. Google Scholar. Table 2: Meteorological conditions that define the Pasquill stability classes, Incoming solar radiation is based on the following: strong (> 700 W m2), moderate (350-700 W m2), slight (< 350 W m2)[13], The stability class can be defined also by using the. Essentially, it is an area source with a third (height) dimension (for example, the fugitive gaseous emissions from, Sources, by urbanization level whether the source is within a city or not is relevant in that urban areas constitute a so-called, Urban source emission is in an urban area, Rural source emission is in a rural area, Puff or intermittent source short term sources (for example, many, Continuous source long term source (for example, most flue gas stack emissions are continuous), Table 2 provides the meteorological conditions that define each class. Dispersion results from local turbulence, that is, motions that last less than the time used to average the transport. AIR QUALITY STANDARDS To prevent or reduce health problems associated with air pollutants, many countries set air quality standards. The Canadian air-quality guideline for ambient SO 2 in the atmosphere is a maximum of 450 g/m 3 (0.17 ppm) over a one-hour exposure (Table 16.3). Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in The appearance of these conditions results in different levels of air pollution characteristic for a given period. Measurements of some meteorological parameters are also carried out at the station to determine the direction of flowing air masses and potential sources of pollution. Effect of meteorological conditions and building location on CO2 concentration in the university campus. Higher levels of air pollution in winter months may also be associated with increased low emissions from local home furnaces, as well as more frequent in these periods, inversion of temperature resulting in smog events. These factors are given in the table 1 7. 2011). Solar radiation increases, This page was last edited on 1 November 2022, at 07:58. For dispersion in the vertical, its all about thermodynamics! If one were to lift a parcel of air from the surface upwards during a temperature inversion, that parcel of air will be cooler than the air surrounding it and sink back to the surface. As mentioned above, dispersion of pollutants is dependent on emission conditions, transport and turbulent mixing. The study uses data collected during a seven-year period (20092015) in the automatic measuring station of immissions located in Eastern Wielkopolska. As the plume of smoke is blown by the wind, it will spread not only westward, but drift outwards from its centerline (an imaginary line drawn down the center of the plume as viewed from above) to the north and south as it moves to the west. For the latter, we have demonstrated the role that dispersion models can play by using two complimentary models, KCLurban . But, pollutants are emitted and subsequently transported at the top of the stack which can be up to 300 m high. Pozna: IMiGW o/Pozna. On the other hand, the permissible level for ozone (Fig. Selain manfaat ekonomi, ada kekhawatiran tentang dampaknya terhadap kualitas udara ambien. Nature, 525, 367371. changes in emission sources). https://doi.org/10.5194/acp-11-8157-2011. Thermo Scientifics primary monitoring system was provided by the monitoring station. The contribution of outdoor air pollution sources to premature mortality on a global scale. 2002). Warszawa: Oficyna Wydawnicza Wyszej Szkoy Ekologii i Zarzdzania. Gurney KR, Razlivanov I, Song Y, Zhou Y, Benes B, Massih MA. For analysis, the results of measurements of air pollution and meteorological data recorded by the Piotrkowice measuring station in the seven-year period (20092015) were selected.

They are made by means of two sensors that measure such air parameters as temperature (C), relative humidity (%), wind direction (0359), and wind speed (m/s). Ventilation. 2015; Nemitz et al. There are several natural and anthropogenic events where passive or chemically active compounds are emitted into the atmosphere. Journal of the Air & Waste Management Association. PubMedGoogle Scholar. However, sometimes the air near the surface (often at night) will cool below the temperature of the air above it, resulting in temperatures that increase with height this is known as a surface temperature inversion. Figure 2 shows averaged daily concentrations of PM10 for both individual months and the average for the years 20092015. On a day with light easterly winds (i.e. 3) Establishing air monitoring surveys. R. Mszros. The dispersion of pollutants in atmosphere is maximum when Environmental lapse rate is greater than adiabatic lapse rate Environmental lapse rate is less than adiabatic lapse rate Environmental lapse rate is equal to adiabatic lapse rate Maximum mixing depth is equal to zero Answer 32. Dispersion and chemical transformation in the atmosphere using mathematical or numerical techniques is called air pollution dispersion modeling [1]. maximum at center of plume 10. Sources of air pollutants are mainly combustion processes, various technological processes as well as vehicle traffic (Cichowicz and Wielgosiski 2015a, b; Gurney et al. Part of Springer Nature. Similarly, Fig. Note that horizontal dispersion can be affected by topographyfor example, sometimes pollution will be blown into the entrance of a valley where it can remain trapped if the wind speeds arent enough to carry it over the ridges that define it. The following pollutants have been measured: particulate matter PM10 (in concentrations ranging from 5.0 g/m 3 to 250 mg/m 3 ), sulfur dioxide (0 to 500 ppb), carbon monoxide (0 to 50 ppm), nitrogen oxide (0 to 500 ppb), nitrogen dioxide (0 to 500 ppb), nitrogen oxides NO x, as the sum of NO and NO 2 (0 to 500 ppb), and ozone (0 to 500 ppb). It was also assumed that the best way to express changes in concentrations recorded at the station would be to analyze their maximum values in terms of seasonality of emissions, including variations in recorded concentrations depending on direction and speed of wind and air temperature and humidity. En effet, la ventilation et l'aration des lieux de travail . APPROACH. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons . 6) is 120g/m3, which is the maximum concentration that can occur on a given day, out of all 8-h rolling values of a given day. Devices operate 24h a day, only with small interruptions (about 1% of the time) dedicated to servicing and calibration. Abstract Modeling of dispersion of air pollutants in the atmosphere is one of the most important and challenging scientific problems. The air monitoring station is located in a 2.53.0m container 2.5m high, which is resistant to external weather conditions. The higher levels of pollution in winter months are represented by PM10 concentrations which exceed the limit values. The nearest human settlements are located in the following distances: 0.6kmPiotrkowice village (532 inhabitants), 1.5kmWygoda village (270 inhabitants), 2.1kmNiedwiady Due village (163 inhabitants), and 3.1kmPwiosek Stary village (263 inhabitants) as well as about 3.5kmtown of lesin (about 3200 inhabitants) and 4.2kmtown of Liche (about 1500 inhabitants).
