Opis:
The migration of the moving dangerous chemicals in soil-water systems represents significant risk to public health and environment. At the present time there is growing scientific concern about the available predicting procedures for environmental assessment of contaminated sites and chemical spills. After considering the various approaches and geodata that may be involved, the stagnate zones model was recognized. The key problem to be considered here deals with the surface concentration distribution, risk evaluation and allowable residue levels for chemicals. It is possible to make forecast and ecology monitoring based on the proposed mathematical model with tabulated migration parameters of the contaminants and soils. The considered method can complement experimental work on the contaminated sites and assist with soil-geochemistry mapping.

Opis:
Nowadays, human activity has been playing an increasing role in determining the quality of surface waters. The aim of the following article is to show an influence of anthropogenic factors influencing the variability of chemical composition of river waters in a catchment area with an agricultural use of lands. The authors carried out the analysis of surface waters quality, made an inventory of pollution sources of surface waters and presented the proposal of quality improvement of surface waters in the Miechów and Kazimierz districts. Research on the concentration of biogenic compounds was conducted in the Nidzica catchment area. Data for research was obtained from the Voivodship Inspectorate for Environmental Protection, County Offices and Commune Offices. The tested area was an agricultural one. The major pollutants of the waters of catchment areas include both area and point pollution. Fertilizers and natural fertilizers are used to raise the yield and then they get into the surface waters by flushing from the fields. The main goal is to investigate the dynamics of changes in the content of nutrient compounds in surface waters during the year (seasonal changes) and in the multiannual period (multiannual changes).

Opis:
Environmental pollution has resulted in several health and physiological problems in both plants and animals. This has witnessed growing number of models for assessment purposes. Some of these provide useful information, and reduce large data for easier understanding by policy-makers. In the current study of pollution, we used data from four locations: Oil Market, Trans Amadi, Borrokiri and GRA in Port Harcourt and a control taken from Federal Land Resource Umuahia (FLRU). A total of 25 composite soil samples were analyzed for physicochemical parameters and heavy metals, by means of a 969 Unicam AAS model series. The data obtained were then subjected to index models. Results showed iron (Fe) to be most abundant metal, ranging from 10.44 to 19.54 mg/kg, then Ni (8.03 to 13.6mg/kg), Cd (3.96 to 5.41 mg/kg), Pb (1.36 to 7.64 mg/kg), Zn (0.09 to 7.24 mg/kg), Cu (0.16 to 0.32) and As (0.07 to 0.11 mg/kg). All metal concentrations were below permissible limits set by NESRA. Contamination factor (Cf) and Igeo revealed moderate to heavy contamination by Cd and Zn. Anthropogenicity revealed that increasing metals in the environment are largely from anthropogenic inputs. The Pollution Index revealed that soils were unpolluted (PLI < 1) with the heavy metals. Furthermore, the Sodium absorption ratio showed that the soils are less sodic and could be good soils for plant growth. All four sites showed a linear relationship between anthropogenicity and geoaccumulation indexes, and so both indexes furnish basically the same information However, pollution from these metals in the study area should be under routine check for possible pollution in the near future, as some metals showed elevated concentrations above background values.

Opis:
The article studies the problem of assessing the quality of atmospheric air in the green areas of the metropolis. The aim of the work is to compare the data obtained by the biomonitoring method with information from unified state environmental monitoring system (USEMS). The sample object of the study is a Udelny park located in the Primorsky district of the city of St. Petersburg. The objectives of the study include the analysis of atmospheric pollution of the Udelny Park by the method of bioindication, comparison of the data obtained with the general telephone indicators, as well as with information from the nearest USEMS posts. When studying the object, the method of V.M. Zakharov was used to study the fluctuating asymmetry of the leaf plates of the hanging birch (Betula pendula Roth.). The site between Udelny Ave., the Vyborg railway line, Testers Ave. and Kolomyazhsky Ave. with an approximate area of 18 hectares was chosen as a model site. The assessment was carried out on 12 pickets, at each 100 samples of leaf plates were taken in total. For comparison, data were obtained from a stationary observation post for the state of atmospheric air pollution, information on the content of pollutants in the air of the Primorsky district. The study found that the quality of atmospheric air in the territory is low. In part of the pickets, the value of the fluctuating asymmetry index was more than 0.054, which corresponds to the V score (critical pollution). These data are generally correlated with information about air pollution in St. Petersburg. Nevertheless, the state of the environment is assessed by the chosen method more critically. This is due to the fact that the biomonitoring method studies pollution from the point of view of direct impact on the ecosystem, taking into account, among other things, the cumulative effect. The result makes us to conclude that it is more correct to use an integrated approach, combining both methods, to assess the stability of urban ecosystems and the quality of the environment in them. It is important to separate information about the quality of the atmosphere in green areas from general data on residential areas.

Opis:
The aim of the study was to investigate how industrial pollutants and change of thermal conditions of winter season in the second half of the 20th century affected the basal area increment (BAI) and the climatic signal in the BAI chronologies of Pinus sylvestris and Pinus banksiana. Samples were collected from 21 trees of both species growing in the Chrzanów Forest District (50°20' N, 19°47' E) which is located between the Upper Silesian and Krakow Industrial Regions. Two cores were taken from each tree. Tree−ring widths were measured at the cores and the BAI for each year in the period 1930−2016 was calculated. The growth reductions of both pine species in the years 1951−1970, increasing of diversity of growth reactions from year to year and also reduction of strength of climatic signal in the period 1963−1994 may have been caused by industry pollution. The reduction of wood growth, the increase of the diversity of short−term incremental reactions and also the reduction of strength of the climatic signal were greater in Jack pine. This indicates that Scots pine was more resistant to pollution. As an industrial production declined and environmentally friendly technologies were introduced in the 1990s homogeneity of growth reactions and strength of dependence between BAI and climate parameters in both species increased. A significant increase in the strength of the relationship between January temperature and BAI of Scots pine and Jack pine was observed in the early 2000s. This may suggest that the vegetation season starts already in January in the study area.

The leaf blades of white ash Fraxinus americana L. and London plane tree Platanus acerifolia Willd. growing in heavy polluted industrial areas were studied for morphological and anatomical changes developed under the influence of industrial contamination. The aim of the investigation was to determine and compare the influences of air polluted with SO2, NxOx, Pb, As, Zn, Cu etc. on the morphology and the structure of the leaves of these deciduous trees. Both species are tolerant to environmental changes but with different environmental characteristics and tolerances and they are widely used for planting. Under polluted conditions, the trees strengthened the anatomic xeromorphic characteristics of their leaf structures, which gave them the opportunity to mitigate the stressful conditions of the environment. The observed responses are regarded as adaptive and compensative to the adverse effects of air pollution.

Opis:
The operation of large power plants, including power stations, and combined heat and power stations, causes the emission of significant amounts of gaseous pollutants into the environment. As a result, in the urban and agricultural areas occurs a pollution of undesirable gaseous substances, such as nitrogen and sulfur oxides. This is especially dangerous for living organisms, soil and water, because, in combination with water vapor, these pollutants are the cause of acid rain. In addition, nitrogen oxides participate in the formation of ground-level ozone, which affects both human health and the condition of existing vegetation. Therefore, the distribution of air pollutants (NO2, SO2 and O3) in the selected urban and rural areas, under the influence of power plants, located in the Lodz Voivodeship, in Poland, in Central-Eastern Europe, was analyzed for a 10-year period (2007-2016). As a result, it was possible to evaluate the impact of the entry into force of Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 “on ambient air quality and cleaner air for Europe” on the changes in emissions and concentrations of pollutants in selected locations. As a result of the analysis, a significant decrease in the concentration of SO2 (by 75% in the urban area and by 59% in the rural area), and small changes (from - 8% to + 12%) in NO2 and O3 concentrations in ambient air were found. This indicates the effectiveness of actions aimed at reducing SO2 emissions, however the influence of the power plants on the concentration of air pollutants in these areas is not clear. At the same time, considering the criterion of permissible concentration of ozone and nitrogen dioxide, although the air quality did not improve, the air quality index can be considered as being in the category of "good".

Opis:
Soil contamination of areas covered by industrial plants and farms is one of the major environmental problems whose weight is underestimated in Poland and Europe. Such regions are usually not as exposed to direct pollution as highly urbanized industrial areas. On the other hand, they are usually less strictly monitored than protected areas. The District of Olkusz, an example of such a region, is characterized by well-developed agriculture, regressing local industry and growing tourism industry. However, it borders with Silesia, a heavily industrized area. The study reports the condition of arable soils in Olkusz District in terms of their contamination with lead, cadmium, zinc and copper. The atomic absorption spectrometry (AAS) method was used to determine the concentrations of the metallic elements. The parameters like pH, content of the clay fraction and content of organic matter have been also taken in consideration to assess the bioavailability of the metals. The analytical results showed that, despite the decreasing impact of the local industry, levels of concentration of all the studied metals are significantly higher than their average concentration in Polish soils. Moreover, all the calculated Pearson correlation coefficients between concentrations of the metals were above 0.9, which means they correlate each other strongly. The impact of the local pollutants (mainly Bukowno smelter) in connection with the proximity of the Silesia and the high vulnerability for contamination of the soils precludes agricultural use of the ground in at least half of the cases.

Opis:
Historia geotermii pod Tatrami rozpoczęła się już w roku 1844, kiedy to Ludwik Zejszner opisał odkryte przez siebie na Jaszczurówce, w Zakopanem, źródło o temperaturze 20,4°C. W roku 1963 wody termalne o temperaturze 37°C uzyskano po raz pierwszy z otworu wiertniczego, wykonanego w Zakopanem, na Antałówce. Utwory wodonośne zalegają na głębokości od kilkuset metrów do 1,5 km w rejonie Zakopanego i od 2,5 do 3,5 km. W północnej części Podhala w rejonie Bańskiej Niżnej i Chochołowa. Temperatura wód zmienia się w zakresie od 20 do 40°C w rejonie przytatrzańskim poprzez około 60°C w rejonie Furmanowej, Poronina, Bukowiny Tatrzańskiej i ponad 80°C w rejonie Białego Dunajca i Bańskiej, a nawet do około 90°C w rejonie Chochołowa. Energia geotermalna zajmuje pierwsze miejsce wśród innych alternatywnych źródeł energii. To niewyczerpalne źródło stawia się wyżej niż, stosunkowo rzadko wykorzystywaną energię wiatrową czy słoneczną, której wydajność ocenia się zaledwie na 20-35%, a wydajność energii geotermalnej wynosi aż 70%. Na terenie miasta Zakopanego ogrzewanie energią geotermalną stało się już o 40% tańsze niż ogrzewanie gazem. W samym Zakopanem poprzez geotermię nastąpiła znaczna redukcja emisji dwutlenku węgla. Całe Podhale powinno być ogrzewane wodą geotermalną, gdyż emisja zanieczyszczeń powietrza w tym rejonie, a w szczególności w Kotlinie Nowotarskiej jest bardzo duża w szczególności w sezonie grzewczym. Ponadto istnieje duża możliwość wykorzystania energii geotermalnej w takich dziedzinach jak rekreacja i balneoterapia.
The history of thermal waters in the region begins in 1844, when Ludwik Zejszner wrote of a thermal spring at 20.4 degrees Celsius that he discovered in Jaszczurówka, Zakopane. In 1963 thermal waters at 37 degrees Celsius were reached the first time from the a well drilled in Antałówka, Zakopane. Water-bearing stuctures lie at the depth of several hundred meters to 1.5 km in the Zakopane region, and between 2.5 and 3.5 km in the northern region of Podhale - Bańska Niżna and Chochołów. The temperatures of these waters vary between 20 and 40 degrees Celsius in the Tatra region, and between 60 degrees near Furmanowa, Poronin, Bukowina Tatrzańska and over 80 degrees in Biały Dunajec and Bańska and even 90 degrees in Chochołów. Geothermal energy is in the first place in the race for alternative energy sources. This renewable sources is valued higher than relatively rarely used wind or solar energy, whose efficacy is estimated at 20-35%, while the efficacy of geothermal energy is 70%. In Zakopane geothermal energy used for central heating is now 40% cheaper than using gas. In Zakopane itself there has been a considerable reduction of CO2 emission as a result of switching to geothermal energy. The whole of Podhale should be heated in this way, since the emission of air pollutants in this region, especially in and around Nowy Targ is enormous especially in winter. Moreover this type of energy would contribute to great changes in other fields, in which it would be possible to use it, such as balneology and recreation.

W pracy przedstawiono wyniki badań imisji lekkich węglowodorów aromatycznych na obszarze wiejskim. Oznaczano emisję benzenu, toluenu, etylobenzenu, meta-, para- i orto-ksylenu (BTEX). Do badań, jako absorbery BTEX, wykorzystano mierniki pasywne z węglem aktywnym. Mierniki eksponowano w okresie wzmożonej emisji niezorganizowanej od 15 stycznia do 14 lutego 2012 roku. Badania prowadzono w 15 punktach pomiarowych w administracyjnym obszarze miejscowości Dylaki (PL). Oznaczenia jakościowe i ilościowe wykonano przy użyciu chromatografii gazowej. Wykazano, że jakość powietrza wiejskiego jest silnie degradowana węglowodorami aromatycznymi, a poziom imisji jest o ok. 20% wyższy niż na terenach miejskich. Nie stwierdzono przekroczeń poziomu dopuszczalnego dla benzenu. Wykazano, że benzen może być znacznikiem dla pozostałych lekkich węglowodorów aromatycznych. Stwierdzono, że za emisję BTEX odpowiedzialne są dwa źródła niskiej emisji niezorganizowanej: emisja z przydomowych kotłowni oraz ruch drogowy. Podkreślono potrzebę rozwinięcia sieci monitoringu powietrza na tereny wiejskie.
This paper presents the results of research into light aromatic carbohydrates on rural area. The levels of benzene, toluene, ethyl benzene, meta-, para- and ortho-xylene (BTEX) were measured. The testing of used passive samplers with active carbon as the BTEX absorber. The samplers were subjected to exposition for the period from 15th of the January to 14th of the February 2012. The testing was undertaken on 15 sites of administrative border of Dylaki village (PL). The qualitative and quantitative measurements were performed by means of gas chromatography. It was showed that the quality of air was being strongly degraded with aromatic hydrocarbons and the level of the immission is about 20% higher than on urban areas. Exceedings of the permissible level were not stated for benzene. It was demonstrated, that benzene can be a indicator for remaining light aromatic hydrocarbons. It was found that two sources of low unorganized emission were responsible for BTEX emission; emission from home boiler rooms and road traffic. A need of developing the net of the monitoring of air for the countryside was emphasized.

Opis:
The developing oil and gas industry in the modern world, including the territory of the Russian Federation, does not remain without a trace for the environment. Land is the national wealth of each state, so it is very important to preserve its natural potential and prevent environmental disasters. Accidents at the territories of operating oil pipelines, which cause great harm to all kinds of natural resources – and first of all to land resources – remain unavoidable. The presented research reveals the methodology of the detailed assessment of the level and degree of soil contamination by oil products. The assessment scale was developed and five zones with different degrees of soil contamination by oil products were established. Using the calculation and a graphic method, a map of zones with the degree of contamination was developed and their exact areas were established. The presented development will be used when carrying out land reclamation of the territory under study.

Opis:
This work was undertaken to determine lipids changes in needles of Scots pine (Pinus sylvestris L.) populations growning on polluted stands near a phosphate fertilizer factory in Luboń, and copper smelter in Głogów and in a control area in Kórnik. Needles from polluted areas had a lower content of total phospholipids than samples from the unpolluted site. Greater changes were detected in membranes of needles collected in October and January. In comparison with the control total phospholipid in needles of populations from polluted areas were 14 to 33% lower. Phosphatidylcholine (PC) phosphatidylethanolamine (PE) and phosphatidylglicerol (PG) were the dominant phospholipids. The analysis of fatty acids in phospholipid fraction showed a decrease of linoleic acid (18:2) and linolenic acid (18:3) contents. The level of polyunsaturated fatty acids in needles of three populations from polluted areas was up to 40% lower as compared with the control. Moreover, phospholipids and their fatty acids showed seasonal fluctuations. The contents of PC, PG and PE increased in autumn and in winter, during the process of cold acclimation. In July, current-year needles did not show significant differences in membrane lipid composition between the polluted areas of Scots pine populations. The results suggest that the lipid changes of needles could be associated with disturbances in phohospholipid metabolism, caused by environmental pollution.

Opis:
As a step towards remediation of sulphur contaminants, this study used a Crowcon Gasman (gas detection instrument) to collect and analyze Sulphuric gas samples from densely populated areas of urban Zaria. The results showed varying concentrations of Sulphur Dioxide (SO2) and Hydrogen Sulphide (H2S). The high concentrations of these pollutants detected can be attributed to increased population growth, increased production of gaseous wastes and increased number of vehicular movement. The results indicate also that the concentrations of pollutant sulphur component SO2 measured at all sampling points, with exception of the control site were hazardous while that of H2S were within safe limit set by FEPA and ACGIH respectively. Statistical tests were performed which established significant variation/relationship between detected pollutants and traffic volume. Findings from this study imply that vehicular emission within urban Zaria is not within the safe limit which further reveals that transport-related pollution in Zaria urban area can be potentially hazardous to health.
