Abstract

The research aimed to assess the content of heavy metals and the toxicity of bottom sediments of the Chancza reservoir on the Czarna Staszowska river in southern Poland. Sediment was collected in three zones at the inlet to the reservoir (3), in the middle zone of the reservoir (2), and in the zone by the dam (1). Total contents of the following heavy metals were determined in air-dry samples of bottom sediments: Cu, Zn, Ni, Cr, Pb, Cd using ICP-AES method. In order to assess the state of conta mination of the bottom sediments with heavy metals, calculated values of the following parameters were used: Mü ller’s geoaccumulation index (Igeo), contamination factor (Cf), as well as the contamination degree (Cdeg). The assessment of toxicity of the bottom sediments was conducted using Phytotoxkit test. Mean contents of heavy metals in the reservoir were highly diversified: Zn (75÷156 ppm), Cu (27÷50 ppm), Ni (7÷19 ppm), Cr (11÷25 ppm), Pb(16÷31 ppm), Cd (0,3÷0,5 ppm). Results from the carried out Phytotoxkit test showed a stimulating influence of bottom sediments on the growth of young roots of the test plants, which may be indicative of increased fertility of these sediments.
