Investigating the significance of dissolved organic contaminants in aquatic environments: Coupling passive sampling with in vitro bioassays.

Popis výsledku v původním jazyce

We investigated the feasibility of coupling passive sampling and in vitro bioassay techniques for both chemical and ecotoxicological assessment of complex mixtures of organic contaminants in water. Silicone rubber passive sampling devices (SR-PSDs) weredeployed for 8-9 weeks in four streams and an estuary of an agricultural catchment in North East (NE) Scotland. Extracts from the SR-PSDs were analysed for freely dissolved hydrophobic organic contaminants (HOCs) and screened for wide range of pesticides. The total concentrations of dissolved PAHs (Sigma PAH(40), parent and branched) in the water column of the catchment varied from 38 to 69 ng L-1, whilst PCBs (Sigma PCB32) ranged 0.02-0.06 ng L-1. A number and level of pesticides and acid/urea herbicides of varying hydrophobicity (log K(OW)s similar to 2.25 to similar to 5.31) were also detected in the SR extracts, indicating their occurrence in the catchment.
