Abstract

A simple and effective analytical procedure was developed for the determination of some organochlorine residues in
mussel samples of two sampling points in Evia Island, Greece. The sample extraction was performed on lyophilized
samples using either the Microwave Assisted Solvent Extraction (MASE) or the Soxhlet extraction technique. Using both
techniques aldrin, endrin and endosulfan sulfate were determined. The quantification of these pesticides was carried out
by Gas Chromatography-Mass Spectrometry (GC-MS) working in the Selected Ion Monitoring (SIM) mode and the
recoveries ranged from 75 to 102% at two spiking levels for 6 replicates.
