Six wildlife species of amphibians, fish and birds were sampled and screened for organohalogen contaminants (OHCs) in a paddy field in Yangtze River Delta, China. High contaminations of chlorinated paraffins were found particularly in terrestrial species. A novel pattern of PCBs with relatively high contribution from octa-CBs to decaCB was observed. A new group of OHCs, with 5–8 chlorines, were found but are not yet structurally confirmed. DDTs was the major organochlorine pesticide contaminant in wildlife. The results show an extensive contamination of OHCs in wildlife in Yangtze River Delta, calling for further (eco)toxicology study and environmental monitoring.
