A multi-residue method for 25 selected pesticides including propanil using an SPE disk has also been developed as a rapid screening method for organic contaminants in river, lake and seawater samples. Cig SPE disks are conditioned with 10 mL of acetone for 3 h. Water samples (1L) are allowed to percolate through the disks in order to trap the residues at a fiow rate of 50 mL min under vacuum. Residues trapped in the disks are extracted twice by eluting with 5 mL of dichloromethane-ethyl acetate (1 1, v/v). The more hydrophobic compounds (log/fow>3) seem to show no...

Part 1, Alpine Water Resources, examines the hydrological basics, the impacts of climate change in the Swiss Alps, and human interventions in mountain waters. Part 11, Biogeochemistry and Pollution of Alpine Waters, deals with the chemistry of mountain rivers, the effects of acid deposition on high elevation lakes, the glaciers as archives of atmospheric deposition, and the occurrence of persistent organic contaminants. 

Despite the strengthening of environmental policies, problems in relation to cadmium and cyanide, dioxin, organic pollution, lake eutrophication, residential sewage, pesticide runoff, industrial discharges, and groundwater contamination by toxics and nitrates also need to be tackled.

Congener 126 is the most potent of the PCBs in binding to the AHH receptor of fish [57]. A number of studies demonstrated the correlation between organic contaminant levels and fish reproductive effects, but specific mechanisms were not identified [58-60] it was assumed that PCBs and PCDD/Fs were the causative contaminants. Wilson et al. [61] demonstrated that fish eggs injected with Lake Michigan lake trout extract exhibited embryonic toxicity.
