Abstract

The eastern area of Poland is the land of great natural worth both on a country and Europe's scale. This area encompasses the valley of the middle-Bug river that is preserved as the Landscape Park. In this research an attempt was undertaken to assess the heavy metal pollution of the environment in the area of the Landscape Park named ,,The Podlasie Ravine of the Bug River". The level of heavy metals in falling dust, soil, and Dandelion (Taraxacum ojficinale Webb.) was being examined in the five localities, situated in the area of the Park. The research showed that none of the mean permissible standard values of the falling dust, Pb, and Cd were outreached; however, it was observed that the fall of Pb was locally higher in relation to the standard Pb fall values in Janów Podlaski. The concentration level of the elements in the soil equaled the ,,O" degree of heavy metal pollution of the soils. In the circumstances of the reaction soil about pH 6- 7 and low concentrations of the metals in the soil the Cd, Pb elements accumulate in Dandelion in trace quantities. The obtained results indicate that there is no threat whatsoever existing in the shape of the heavy metals in the area of the Landscape Park ,,The Podlasie Ravine of the Bug River".

Abstract

The aim of the paper is to compare nitrate concentrations in samples of supply water as well as

water from deep and dug wells located in the eastern region of Poland. Additionally, samples of bottled water

(spring and natural mineral), certifi ed by the Institute of Mother and Child and the Children’s Memorial Health

Institute, were subjected to analyses. On the basis of the obtained results, health risks related to the occurrence

of methemoglobinemia in neonates and infants were evaluated. The risk analysis was performed according to

the procedure recommended by the United States Environmental Protection Agency. Nitrate concentrations in

the examined samples ranged from: 0.153–161.1 mg/l. The lowest concentration of nitrates was determined in

the samples of bottled water, the highest being detected in the water from dug wells. It was found that nitrate

concentration in samples of bottled and supply water did not pose any risk to the health of neonates and infants.

The highest health risk related to methemoglobinemia occurs for neonates consuming water originating from

dug wells. The risk decreases along with the age of an infant.

Abstract

In this paper, the results of the analyses of selected chemical water quality parameters and taxonomic composition of macroinvcrtcbratcs of the Liwiec River and its chosen tributaries (central-eastern Poland) arc presented. Chemical and biological water quality assessment was performed, and four biotic indices were tested: Belgian BBi, French IBGN, British BMWP/OQR, and biotic index BMWP-PL developed for Polish rivers. Correlations between the values of the latter and chemical water parameters show that BMWP-PL is a useful tool for the assessment ofwater quality of lowland rivers in Poland (similar to the Liwiec).
