Abstract

V originále

Bioaccumulation of xenobiotics in soil invertebrates is an important process, because it can lead to the toxic action in their bodies or to the biomagnification of food chains. In our study, two hotspots in the Czech Republic were selected which were seriously contaminated by persistent organic pollutants, mostly by PAHs and DDTs. The soils were sampled, dried and sieved to 2mm and adults of earthworm Eisenia fetida from laboratory culture were exposed for 14 and 28 days. The exposure time (14 or 28 days) didnt affect the bioaccumulation suggesting that 14 days exposure is sufficient to reach a plateau of the uptake. Soil-biota accumulation factors (BSAF) were calculated for 16 PAHs, 7 PCBs, HCHs, HCB, and DDTs. The results were compared with BSAF values for the earthworms collected at the localities. The differences up to several orders of magnitude were found between BSAF of indigenous earthworms and E. fetida. Our results suggest that the laboratory bioaccumulation test with E. fetida may underestimate the real bioaccumulation substantially.
