Results of lead and cadmium contents in soil adjacent to European highway E30 in the East of Poland were presented in the study. Soil samples were collected at three distances: 0, 50, and 100 m from the track, and at two depths: 5-15 cm and 35-45 cm. Soil pH, content of silt and clay particles, organic matter content, types of underlaying rock and land use methods were tested. The total contents of...
Decomposition process in the soil of desert, steppe and mountain landscapes was studied in the region of Caucasus (Daghestan). The study sites differed mainly in average temperature and humidity being generally extremely dry with soil poor in organic matter. Two methods – bags with grass and cellulose filter paper discs were used. No dependence was found between the rate of decomposition of introduced...
The influence of Cr (III) and Cr (VI) on biochemical reactions in the environment depends in part on the possibility of its getting from soil to soil solutions. The various methods of sequential extraction of Cr from soil were studied (Tessier et al. [1, 2], Rudd [3], BCR [4-7], Gatehouse [8], Kersten and Förstner [9], Psenner [10], Sposito [11]) in order to characterize chemical fractions. It was...
One-year-old seedlings of silver birch (Betula pendula Roth.) were grown in pots filled with a soil substrate that originated from an area polluted by a phosphate fertiliser factory and characterised by a high soil Al level and low Ca/Al ratio or with a substrate from an area regarded as free from toxic pollution. In addition the effect of fertilisation with a mixture of nutrients was evaluated. Birch...
The concentration levels of the following metals: Cd, Pb, Zn, Mn, Fe and Ni in falling dusts, soil and dandelion (Taraxacum officinale Webb.) were examined in selected areas of Southern Podlasie Lowland. The research was conducted from 1995 to 1999. The metals were marked by means of the AAS technique. The deposition of Cd and Pb metals did not exceed the values standardized in the Polish legislation,...
Intensive microbial growth on 4 nutrient media (containing glucose, starch, nutrient broth or peptone + yeast extract) in soil suspension experiments, changing pH (acidification or alkalization) caused partial liberation of Cd sorbed by soil particles to liquid phase. At the same time a considerable transformation of the solid phase Cd to soluble in 0.1 N NaOH form was observed. Increased Cd concentration...
The objective of this research was to evaluate bacteriological and parasitological pollution levels of soil, groundwater, surface water and river sediment in the vicinity of a pig farm. The microbiological examinations of soil and water environment within the pig farm area and around it showed considerable pollution with animal droppings and municipal sewage coming from a breeding farm and farm buildings...
Studies on element concentration in soils, plants, invertebrates and food, and body parts of synanthropic bird nestlings in polluted and unpolluted urban environments have been reviewed. Different ways of intake of elements by nestlings living in urban environments are presented. This required the determination of differences in element concentration in soils, plants, invertebrates and nestlings'...
