Abstract

A simultaneous determination of five organochlorine herbicides and two fungicides in blue mussel (Mytilus edulis) by gas chromatography was developed for residue analysis. The average recoveries of the herbicides and the fungicides were in the ranges of 85.0-92.6% and 63.7-74.8%, respectively.
Monitoring of the residual pesticides in blue mussels from the North Harbor of Osaka Bay by the present method was carried out from July 1984 to November 1985. Oxadiazon was found for the first time in these organisms at levels of 0.20-0.35ppm in summer (July and August 1984, and June and July 1985). The presence of oxadiazon, detected by ECD-GC, was confirmed by GC-mass spectrometry. The other pesticides were not detected.
