The results of studies on the air pollution and on the natural sedimentation from the atmosphere in the South Shetlands are (Admiralty Bay) are presented. The amount of dust in the air varied from 0.11 to 10.90 μg x m-3 (the mean being 3.70 μg x m-3). The total amount of substances transported from the atmosphere in the Admiralty Bay region was estimated at 12.7t x km-2 per year, whereas the precipitation transports some 2.5 t x km-2 per year in this region. Preliminary data on the contents of Cu. Cd. Co. Ni. Pb and Zn in the samples of surface waters, snow and rain in the region of the Admiralty Bay are presented and compared with the results of the authors.
Microbiological and chemical analysis of air was carried out on the area of landfill of wastes other than inert or hazardous. The landfill covers 20 ha and 40 000 Mg of wastes is deposited annually. Municipal waste is not segregated at the landfill. The research was conducted in April, May and November 2012. Number of the psychrophilic and mesophilic bacteria and fungi was estimated by a culture-based method. Quantitative determination of sulfur compounds and meteorological and olfactrometric examinations were also carried out. Chemical analysis was conducted with a Photovac Voyager portable gas chromatograph. Air samples were collected at 5 points. The largest group of microbes were psychrophilic bacteria, especially in summer. The highest concentration of hydrogen sulfide and other odorants was found at leachate tank and landfill body. According to the Polish Standard for the assessment of atmospheric air pollution the air in the area of the landfill is classified as not contaminated and sporadically moderately contaminated. In spring and summer the number of microscopic fungi was increased also in control samples.
The paper investigates the air quality in the urban area of Warsaw, Poland. Calculations are carried out using the emissions and meteorological data from the year 2012. The modeling tool is the regional CALMET/CALPUFF system, which is used to link the emission sources with the distributions of the annual mean concentrations. Several types of polluting species that characterize the urban atmospheric environment, like PM10, PM2.5, NOx, SO2, Pb, B(a)P, are included in the analysis. The goal of the analysis is to identify the most polluted districts and polluting compounds there, to check where the concentration limits of particular pollutants are exceeded. Then, emission sources (or emission categories) which are mainly responsible for violation of air quality standards and increase the adverse health effects, are identified. The modeling results show how the major emission sources – the energy sector, industry, traffic and the municipal sector – relate to the concentrations calculated in receptor points, including the contribution of the transboundary inflow. The results allow to identify districts where the concentration limits are exceeded and action plans are needed. A quantitative source apportionment shows the emission sources which are mainly responsible for the violation of air quality standards. It is shown that the road transport and the municipal sector are the emission classes which substantially affect air quality in Warsaw. Also transboundary inflow contributes highly to concentrations of some pollutants. The results presented can be of use in analyzing emission reduction policies for the city, as a part of an integrated modeling system.
The aim of this study was to identify a suitable lichen species for the long−term monitoring of heavy−metal atmospheric pollution in Svalbard. Cladonia and Cetraria s.l. species that have been widely used until now for assessing heavy−metal deposition in the Arctic are in decline over extensive areas of Svalbard, mainly due to climate change and over−grazing by reindeer. Cetrariella delisei , rarely used for biomonitoring, is still common and widespread in this area. Levels of Cr, Ni, Fe, Cu, Pb, Zn, Cd and Mn were measured in three lichen species: Cetrariella delisei , Cladonia uncialis , Flavocetraria nivalis and in a moss Racomitrium lanuginosum from Sørkapp Land, South Spitsbergen. The results imply that Cetrariella delisei can be safely compared to Cladonia uncialis for identifying the levels of heavy metals, but direct comparison between Cetrariella delisei and other species studied is more difficult owing to differences in levels of heavy metals even in samples from the same site.
The major aim of the study was to identify the relationships of photosynthetic pigments with elemental contents of plants exposed to various ambient air conditions. Lolium multiflorum L. plants were exposed at five sites varying in environmental characteristics, including potential air pollution levels. The effect of air pollution by trace elements on plants was examined. Selected trace elements (Pb, Cd, As, Ni, Cr), some macro-elements as well as chlorophyll content were measured after each of four series. The graphical visualization revealed groups of sites with similar response of elements and chlorophyll contents. Sites located outside the city were grouped into one, and two urban sites were grouped into another. The trace element contents were relatively low and, excluding Ni and As, did not reach toxic levels in dry mass of leaves. However, some relations could be noted, which indicates the sensitivity of the photosynthetic process even at low levels of trace elements in ambient air. Chlorophyll b was found to be more sensitive to most of the analyzed trace elements than chlorophyll a. The results revealed chlorophylls, K and Na as indicators of plant stress caused by trace elements present in ambient air, even at relatively low levels.
Background: Air pollution is a severe problem in Poland, with Kraków area being among the regions with the worse air quality. Viral croup or pseudocroup is a common childhood disease that may manifest with severe upper respiratory tract obstruction. Our aim was to evaluate the associations between incidence and severity of viral croup symptoms among children living in Kraków area, Poland, and air pollution. Methods: Th e retrospective cross-sectional study included Kraków area residents <18 years of age admitted to the Emergency Department of St. Louis Children Hospital in Kraków, Poland over 2-year period. Daily mean concentrations of air pollutants: particulate matter (PM10 and PM2.5), nitric oxides (NOx), carbon oxide (CO), sulfur dioxide, ozone, and benzene were retrieved from public database of measurements performed at three local stations. Numbers of cases of viral croup per week were correlated with weekly mean concentrations of air pollutants. Mean air temperature was treated as a cofactor. Results: During the studied period, mean concentrations of PM10, PM2.5, and NOx exceeded the allowable levels (yearly means) specifi ed by Polish law regulations. Signifi cant positive correlations of moderate strength were observed between weekly mean concentrations of most air pollutants, especially PM10, PM2.5, CO and benzene, and numbers of cases of viral croup recorded per week, confi rmed in the analysis restricted to non-holiday period and to winter months only. Th e correlations between NOx, CO, benzene and croup prevalence were independent of temperature in non-holiday period. Conclusions: Our results support adverse impact of air pollution on children’s respiratory health.
Air Pollution in Poland – Condition, Causes and Effects. In the recent years the air in Poland seems to be the most polluted in Europe (it is worse only in a few times smaller Bulgaria). The concentration of particulate matter PM10 and PM2.5 and polycyclic aromatic hydrocarbons (PAHs), represented by benzo(a)pyrene are among the highest in European Union countries. They are highly toxic, especially PAHS, which damage the hematopoietic system, accumulate in living organisms leading to a cancerous process, they cause damages to the central nervous system and infertility. It is estimated that high air pollution causes 45-47 thousands premature deaths in Poland every year, as well as growth frequency of allergies and chronic diseases. Polish society loses about 520,000 potential years of life, and the economy of 18.5 million work days. It’s a very high price. The weather determines to a large extent the air pollution. The smog episode is usually accompanied by low wind speed or atmospheric silence, reduction of visibility and thermal inversions. However, the biggest problem is low emission, which is mainly related to individual heating of buildings (78-87% of the total emission of benzo(a)pyrene. The reasons for such poor sanitary condition of the air in Poland are complex and to a large extent they result from spatial chaos and lack of spatial planning, but also from general policy country. The most important reasons are i.a.: the lack of a planning policy and a sustainable transport policy, persistent subsidies for unprofitable coal mines, the lack of a policy promoting renewable energy sources and “clean” technologies, high gas price (the highest in Europe) and no subsidies for the poorest, scattered buildings which hinders access to system heat, inefficient and unsuitable transport based on road transport road and individual cars (often old, Diesel) etc.
Air Pollution and Energy Unefficiency of Settlement Structures in the Context of Spatial Chaos in Poland (Chosen Examples from Lower Silesia). The deregulated spatial planning system in Poland has led to an emergence of incalculable economic, environmental and public costs that burden the society. Investment liberty is accompanied by a lack of coordination in the development of housing areas with public transport, electricity, gas and heating infrastructure. At the same time, revitalization is interpreted as a form of physical modernization of buildings, but not as social renewal. The result of spatial disorder is a reduction of energy efficiency of entire settlement structures, not just individual buildings. Old-fashioned methods of supplying buildings with heat, responsible for local emission, are sustained. Comprehensively, this condition contributes to the deterioration of air quality indicators in Poland.
