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.

Opis:
The research on the influence of pollution emitted by the WBM-30 bituminous mass factories on the winter wheat-crop was carried out in 1981. The factory was situated in the agricultural area far from the farm buildings in the village of Trzebownisko. The experimental area was divided into four zones (three zones of pollution and one control zone). The wheat ear samples were collected during full grain ripeness per 100 ears from different plantations in three repetitions in each zone. They showed that all examined features, such as, e.g. the average ear length and 1000 grain mass were substantially different between the 1st pollution zone and control zone.
Wytwórnie mas bitumicznych zlokalizowane są na obszarach rolniczych z dala od zabudowań wiejskich. Ich wydajność masy bitumicznej wynosi od 30 do 100 ton w ciągu jednej godziny. Badania nad wpływem emitowanych zanieczyszczeń na plonowanie pszenicy ozimej przeprowadzono w 1981 roku. Zakład o wydajności około 30 ton zlokalizowany był w pobliżu miejscowości Trzebownisko. Teren badań podzielono na 4 obiekty, 3 obiekty w strefie zanieczyszczonej oraz obiekt kontrolny. Próby kłosów pszenicy ozimej pobierano po 100 kłosów w trzech powtórzeniach w każdym obiekcie doświadczalnym, w czasie pełnej dojrzałości ziarna. Otrzymane wyniki badań w zakresie plonowania tego zboża, opracowano statystycznie. Wszystkie badane cechy różniły się istotnie pomiędzy obiektem kontrolnym a I strefą zanieczyszczeń.

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:
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:
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:
The investigations were carried out in 2002-2006 in two municipalities of Konopnica and Jastków close to the western part of Lublin, Poland. The aim of the study was to identify the condition of bee flora and determine the floristic richness depending on the biotops in agricultural landscape. Flora of the anthropogenic refuge areas consists of 214 species, among them 80% were flow taxons. Apophytes (162 species - 78%) predominated on all types of biotops under consideration. Perennials predominated in flora of boundary strips and bush communities. Mainly annual (40%) and biennial (15%) species comprise the flora of fallows. A great number of bee taxons represent meadow, segetal or ruderal communities. Most of flow plants compose loose patches, but their successive blooming ensures a source of food for Apoidea from early spring till the end of summer. The flora of boundary strips, bush communities and fallows significantly increases the biodiversity in agricultural landscape. The treatments including sowing, mainly on fallows with nectariferous and polleniferous species, would enrich generally weak flows in highly agricultural landscape.
Badania prowadzono w latach 2002-2006 na terenie gmin Jastków i Konopica położonych w bezpośrednim sąsiedztwie miasta Lublina. Dokonano inwentaryzacji roślinności w obrębie miedz, gruntów odłogowanych oraz zadrzewień śródpolnych ze szczególnym uwzględnieniem roślinności dostarczającej pożytku nektarowego i pyłkowego. Ogółem w obrębie obserwowanych biotopów zanotowano 214 gatunków roślin, w tym 80% stanowiły taksony pożytkowe. W analizowanej florze przeważały apofity - 78% nad gatunkami obcymi (kenofitami). We florze miedz i zadrzewień śródpolnych przewagę stanowiły gatunki wieloletnie. Taksony krótkotrwałe (40% - jednoroczne i 15% dwuletnie) dominowały na gruntach odłogowanych. Zdecydowana większość gatunków pożytkowych reprezentuje zbiorowiska łąkowe, segetalne i ruderalne. Większość z nich występuje w luźnych skupiskach, ale ich sukcesywne kwitnienie zapewnia, na badanym terenie, ciągłość taśmy pokarmowej od wczesnej wiosny do późnego lata. Miedze, zadrzewienia śródpolne oraz odłogi, stanowią ważne w krajobrazie rolniczym ostoje roślinności pożytkowej jednocześnie zwiększają walor bioróżnorodności flory stycznej tych terenów. Wydaje się, że ten typ siedlisk można wykorzystywać do podsiewania gatunków nektarodajnych i pyłkodajnych w celu wzbogacania generalnie słabych pożytków na terenach rolniczych.

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:
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:
The article presents important problems occurring in the operation of large-size steel structures protected by paint coatings. In our atmospheric conditions, corrosion of steel structures cannot be avoided, even with the use of protective coatings. The problem of environmental pollution with corrosion products and exfoliated paint then appears. When designing corrosion protection, durability of protection is assumed based on environmental corrosivity categories, but in practice degradation of paint coatings can occur much faster. The problem of premature peeling of paint results, among other things, from its faulty application and use. Steel structure repairs are usually carried out comprehensively, and new protection requires the removal of damaged coatings, mainly by sanding. As a result of the mechanical action of the abrasive material, old paints and corrosion products are removed, which results in a very large amount of waste that settles on the adjacent area. Due to the age of paint removed, this waste often contains compounds such as lead, chromium or zinc, which pose a real threat to the natural environment around the renovated buildings. In the article, based on the observations carried out directly on the exemplary structures in renovation, the actual scope of the waste emission was determined. This is a contribution to further spectrometric studies to determine the exact area of contamination and to identify heavy metals in the waste arising from the renovation of steel structures with paint coatings.

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:
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:
Celem prezentowanych badań była ocena zagrożenia ze strony intensywnie zagospodarowanych przemysłowo i rolniczo obszarów Wrocławia dla wód podziemnych sąsiadujących z nimi terenów wodonośnych. Na skutek przeprowadzonych prac terenowych i laboratoryjnych zdiagnozowano potencjalne ryzyko związane z napływem wód o podwyższonych stężeniach jonów niklu i potasu. Dla metali tych wykonano model migracji masy w wodach podziemnych. Obejmował on okres 10 lat, zakładając charakter zanieczyszczenia incydentalny – niklem i ciągły – potasem, na obszarach poza terenami wodonośnymi. W wyniku prac modelowych wykazano, że w badanym okresie nie dojdzie do przemieszczenia się jonów niklu w kierunku terenów wodonośnych. Możliwa jest nawet redukcja stężeń tego metalu na skutek procesu sorpcji. W toku prac modelowych stwierdzono możliwość niewielkiego zwiększenia stężeń oraz migracji jonów potasu, szczególnie z sąsiadującego z terenami wodonośnymi cieku Zielona, nie stanowi ona jednak zagrożenia dla ujęć terenów wodonośnych Wrocławia.
The aim of this study was to risk assessment from the intensely developed industrial and agricultural areas of Wroclaw for groundwater of neighboring water-bearing area. As a result of field and laboratory work, a potential risk connected with the inflow of waters with increased concentrations of nickel and potassium ions was diagnosed. For these metals mass transport model in groundwater was performed. It covered a period of 10 years assuming the incidental nature of nickel contamination and continuous potassium pollution. As a result of modeling works, it was shown that in the studied period there will be no transport of nickel ions in the aquifer towards waterbearing area. It is even possible to reduce the concentrations of this metal due to the sorption process. During the modeling was identified also possible increase of concentration and migration of potassium ions, especially from the Zielona stream, however, it is not a threat to the water intakes of Wrocław.

Opis:
W prezentowanej pracy oceniano stopień zanieczyszczenia mikrobiologicznego powietrza w strefie emisji mechaniczno-biologicznej oczyszczalni ścieków w Chociwlu k/Stargardu Szczecińskiego. Próbki powietrza atmosferycznego do badań pobierano w 8 punktach pomiarowych zlokalizowanych na obszarze oczyszczalni ścieków i w odległości do 120 m od „biobloków”. Pomiary wykonywano w latach 2005 - 2006. Próby powietrza do badań mikrobiologicznych pobierano metodę sedymentacyjną. W ramach badań oznaczano ogólną liczebność bakterii, promieniowców, bakterii Pseudomonas fluorescens oraz liczebność grzybów. Stopień zanieczyszczenia powietrza atmosferycznego oceniano w oparciu o Polskie Normy - PN-89/Z04111/02 i 03. Dodatkowo określano liczebność bakterii Escherichia coli. Wszystkie oznaczenia wykonywano w trzech powtórzeniach. Oceniając wpływ oczyszczalni ścieków na mikrobiologiczną jakość powietrza atmosferycznego stwierdzono, że liczebność badanych grup drobnoustrojów zmieniała się w czasie i w przestrzeni. Pod względem bakteriologicznym powietrze na terenie oczyszczalni oraz na obszarze wokół obiektu określono jako silnie zanieczyszczone, przy czym istotny wpływ na ocenę miała stosunkowo wysoka - w porównaniu z normą - liczebność promieniowców (średnio 276 jtk w 1 m³ powietrza przy komorach napowietrzania i 178 jtk·m⁻³ w odległości do 120 m.). Oznaczona w badaniach liczebność grzybów klasyfikowała powietrze jako wolne od zanieczyszczeń, niezagrażające człowiekowi i środowisku naturalnemu (niezależnie od pory roku i odległości od źródła emisji). Obecność bakterii Escherichia coli, uważanych za wskaźnik zanieczyszczenia sanitarnego powietrza, stwierdzono jedynie na terenie oczyszczalni ścieków, wokół emitorów bioaerozoli.
The paper presents the evaluation of air microbial pollution level in the area of mechanical-biological sewage treatment plant in Chociwel near Stargard Szczeciński. Samples of atmospheric air were taken for determinations at 8 measurement points within the sewage treatment plant and at the distance of 120 m away from the „bio-blocks”. The determinations were made in 2005 - 2006. Air samples for microbial assays were taken by the means of sedimentation method. The total number of bacteria, actinomycetes, Pseudomonas fluorescens bacteria and fungi were determined. The level of atmospheric air pollution was evaluated on the base of Polish Norms - PN-89/Z04111/02 and PN-89/Z04111/03. In addition, a number of Escherichia coli bacteria was assessed. All determinations were made in three replications. The evaluation of the sewage treatment plant influence on microbial quality of air revealed that a number of determined microorganisms varied in time and space. In bacteriological aspect, the air within sewage treatment plant and around was considered as strongly polluted, but relatively high - as compared to the norm - number of actinomycetes (276 cfu in 1 m³ of air at aeration chambers and 178 cfu per m³ at the distance of 120 m) had a significant influence on the evaluation. The number of determined fungi classified the air as free from pollution the not hazardous to the man and natural environment (regardless the season and distance from the emission source). The presence of Escherichia coli bacteria considered as an indicator of air sanitary pollution was found only in the area of sewage treatment plant around the bio-aerosols emitters.
