Abstrakt:	The article cites a study on trophic transfer efficiency of DDT to Lake Trout from their prey. Buildup of DDT concentrations in fish-eating birds has been shown to cause shell thinning in the eggs of these birds, and consequently has led to reproductive failure in these birds. Risk assessment models have been developed to predict risk to fish-eating birds under various scenarios of environmental contamination. It was concluded by the researchers that net trophic transfer efficiencies of total DDT to lake trout from their food tended to decrease with increasing ration size.
