Examination of Pollution by Organochlorine Herbicides and Fungicides in Yodo River and Osaka Bay

Studies on Environmental Contaminants in Food. 3

Abstract

A survey of pollution by five organochlorine herbicides and two fungicides was accomplished in pond snail (Cipanogopaludina chinesis malleata), blue mussel (Mytilus edulis), river water and sea water from Yodo River and Osaka Bay. Oxadiazon, bentiocarb and CNP were detected in pond snail and blue mussel at levels of 48.0-580ppb, 60.0-80.0ppb and 11.2-35.0ppb, respectively, from May to August 1986. River water from one side and sea water contained the same herbicides as the shellfishes (pond snail and blue mussel) and the concentrations were about 1/1000 of those in the shellfishes. The presence of the herbicides, detected by ECD-GC, was confirmed by GC-mass spectrometry.
