The analysed area was used for industrial activity for over 130 years. During that time many pollutants (including heavy metals) have been emitted by industrial plants and infiltrated into the soil. This article presents the properties of the soil from industrial sites located in Zielona Góra and analysis of its physical and chemical characteristics.
Lung cancer risk factor in the immigrant population of an industrial area in Poland was examined in a case-control study. Both, relative and summary risks were calculated with adjustment for the following factors: cigarette smoking, alcohol consumption, atmospheric pollution in the place of residence, occupation, education and age. The multivariate logistic analysis indicated that cigarette smoking was a dominant risk factor. In addition, the following factors were confirmed to be significant lung cancer risk factors in the immigrant population of Upper Silesia (Poland): residence in the area of the greatest ecotoxins' concentration; work as toolmakers or manual laborers and seemingly, as coal-miners; lack of university or secondary education, and vodka consumption.
The article presents a new tool for modeling parts produced by rapid prototyping (RP) technologies that has great potential for building structures with programmable properties, especially for items related to the energy dissipation during deformation. Using a wide variety of building materials and controllable part growing is the most important benefit for industry implementation of RP technology. Mass deployment is also hampered by the high price of equipment and materials for the technology.
The Legnica-Głogow Copper Mining District has been the site of metal mining for more than 50 years. Intensive environmental actions have, more recently, been aimed at reducing emissions of harmful substances in the region. We compared the blood lead concentrations of children resident in the copper smelting district in southwestern Poland in 1995 and 2007. The sample included 1,405 children, 7-15 years of age, resident in the same communities in the Legnica-Głogow Copper Mining District in 1995 (432 boys, 403 girls) and 2007 (279 boys, 291 girls). Blood samples were drawn (venipuncture) and analyzed for lead levels (Pb-B) with the same protocol in both years (atomic absorption spectrometry in a graphite furnace). Analysis of covariance, with age and age squared as covariates, was used to compare blood lead levels between years, regions (Głogow and Legnica), and genders. The prevalence of children with blood lead levels >6 μg/dl was compared between years, regions, and genders, and was compared with the chi square statistic (χ²). Blood lead level was significantly higher in 1995 (7.52±0.12 μg/dL) compared to 2007 (4.80±0.16 μg/dL), a decline of 2.72±0.19 μg/dL over the 12-year interval. Blood lead levels were higher in boys than in girls in each year, and declined between 1995 and 2007 in each gender, 8.61±0.16 μg/dL and 5.31±0.23 μg/dL, respectively, in boys, and 6.43±0.17 μg/dL and 4.29±0.22 μg/dL, respectively, in girls. Percentages of high blood lead levels (>6 μg/dL) were significantly higher in boys than girls in both years (1995: 77.5% and 51.9%, respectively; 2007: 32.6% and 16.5%, respectively), and declined significantly between 1995 and 2007 in both genders. Blood lead levels decreased over the interval of 12 years in school children resident in the Legnica-Głogow Copper Mining District.
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.

Floristic composition in three industrial areas with soils contaminated by heavy metals (As, Cd, Cu, Hg, Pb, Zn) and organic pollutants (polychlorinated biphenyls) was studied. The content of Pb was only significantly correlated with the floristic composition and explained 13.8% of its variability considering spatial dependency of the sites. No correlation was found for PCBs. Altogether, 237 plant vascular species were found at three study sites (117, 133 and 105, respectively). The three study areas differed in their species composition represented by their own characteristic species. The gradient in the content of natives/non-natives, species number, prevailing life forms and indicator values for plant species investigated was revealed. Based on our results, for phytoremediation purposes we can select productive plant species with high biomass and ability to accumulate large amounts of heavy metals or organic compounds and surviving on soils with low mineral content.
The objective of the study was to evaluate the impact of nitrogen fertilizer industry pollution on epiphytic lichen communities. The study plots are located in Scots pine Pinus sylvestris stands at different distances (up to 12 km) to the northeast and southwest of the nitrogen fertilizer producer plant in central Lithuania. The stands were semi-mature and mature and growing on sandy sites of the Vaccinio-myrtillosa site type. Species richness, composition and index of atmospheric purity (IAP) were assessed at each site. Species diversity was calculated by grouping species by their ecological values for eutrophication. Species frequency was calculated according to lichen life strategies (growth forms, photobionts, reproductive strategies). Twenty lichens species were recorded in the surrounding of the pollution source. An increase in species richness and diversity was found with increasing the distance up to 10 km from the plant. Based on IAP values three zones (< 5, 5–10, > 10 km) with different air pollution were distinguished. The increase in species richness was related to the increase in eutrophication-tolerating species along with sensitive to pollution species. The lichen diversity value of nitrophytic species (LDVnitro) increased with increasing distance from the pollution source. Foliose and fruticose growth forms were both positively significantly related with the distance, being common in the plots with lower level of pollution. Crustose lichens are less sensitive to this factor and the prevalence of crustose thalli was found in the nearest vicinity to the plant.
This study investigated heavy metals in soils and agricultural products near an industrial district in Dongguan City. The concentrations of Cu, Zn, Pb, Cd, Hg, and As in soil and agricultural products from vegetable and banana fields were determined. Results indicated that except for Zn in one sample and Cd in five samples, the majority of the samples were notably enriched by heavy metals compared with background values. The concentrations of heavy metals (mg·kg⁻¹ dry soil) in agricultural soils in the study area ranged from 22.2 to 93.0 for Cu, 31.2 to 213.6 for Zn, 47.6 to 133.5 for Pb, 0.01 to 0.67 for Cd, 0.15 to 0.56 for Hg, and 20.5 to 28.9 for As. Among these soil samples, concentrations of Cu, Zn, Cd, and Hg in 20.6%, 8.8%, 29.4% and 38.2% soil samples, respectively, exceeded Chinese maximum allowable concentrations (MAC) for agricultural soil. The concentrations of Zn, Pb, and Cd were significantly higher in vegetable than in banana fields. Cu, Zn, Pb, Cd, and Hg accumulated in the topsoil of vegetable fields, but only Pb and Hg accumulated in banana fields. Zn, Cd, and Hg accumulated more easily in flowering cabbage than other vegetables. Cu, Zn, and As were accumulated more easily in banana than lettuce, bunching onion and eggplant. Therefore, the findings suggest more attention should be focused on the accumulation of heavy metals in banana. This study presents a practical methodology for screening crops with lower bio-concentration factors for heavy metals to reduce metal contaminants in the general food supply chain.
The study was to examine the incidence of keratinolytic fungi in the lagoon with acidic petroleum wastes (before bioremediation) at a petroleum refinery situated within a highly populated area. High concentrations of petroleum hydrocarbons (non-polar and polar aliphatics and PAHs) made the growth of keratinolytic fungi in clay and litter from the lagoon impossible. The natural self-purification process considerably decreased the hydrocarbon contamination, increased the pH and caused the abundant growth of Trichophyton ajelloi in organic soil. This soil included the root-adjacent material from the grass growing in several green oases at the lagoon. It is possible that the strains of Trichophyton ajelloi adapted to the extreme lagoon's conditions actively participated in the soil self-purification process. The fungal species isolated in the present study did not pose a threat to public health. However, petroleum contaminants may support the growth of potential pathogens, for example Microsporum gypseum, in other types of soils.
W niniejszej pracy oceniono zróżnicowanie składu gatunkowego drzew i krzewów porastających teren Elektrowni „Pomorzany” w kontekście weryfikacji doboru tych gatunków do lokalnych warunków miejsko-przemysłowych. Stwierdzono występowanie 761 drzew reprezentujących 34 gatunki. Największy udział w strukturze gatunkowej drzew (18%) stanowiły topole (Populus alba, P. nigra, P. canadensis, P. tremula, P. simonii). Krzewy na badanym terenie występują w ilości 1497 egzemplarzy, reprezentujących 27 gatunków. Znaczący udział w strukturze gatunkowej krzewów na tym terenie (19%) odgrywają róże (Rosa sp.). Zieleń zakładową Elektrowni „Pomorzany” należy uznać za urozmaiconą i dobrze skomponowaną, z właściwym doborem gatunków drzew i krzewów. Bieżąca pielęgnacja staje się jednak utrudniona w związku z narastającym zagęszczeniem, szczególnie krzewów, oraz zacienieniem spowodowanym silnym rozwojem koron drzew.
