Metal bioavailability is a key factor in risk assessment procedures for contaminated sites. The goal of our study was to evaluate metal bioavailability and toxicity in long-term contaminated soils in the Tarnowskie Gory area of the Silesia region of Poland. Forty diverse soils were collected throughout the study area. Metal availability was measured using neutral salt extractions, a sequential extraction...
The Warmia and Mazury District (northeastern Poland) is oriented towards agro-forestry and is less populated then other regions of Poland. The main objective of the present study was to characterize the effects of road traffic (road S 51) on an increase in the concentrations of lead and cadmium in the soil surface layer and cereal grains (wheat and barley grown on an experimental farm). The concentrations...
This study was based on tuber samples from the field experiment in 1996-1998 on weak loamy sand soil in a system of randomised sub-blocks. The experimental factors were: ways of nursery and varieties (Swojecka, Kulista Czerwona IHAR, Kulista Biała IHAR). Herbicide application elevated both cadmium and nickel contents in Helianthus tubers as compared to control. Tubers of Swojecka Czerwona cv. were...
