Abstract
A simple and effective analytical procedure was developed for the determination of some organochlorine residues inmussel samples of two sampling points in Evia Island, Greece. The sample extraction was performed on lyophilizedsamples using either the Microwave Assisted Solvent Extraction (MASE) or the Soxhlet extraction technique. Using bothtechniques aldrin, endrin and endosulfan sulfate were determined. The quantification of these pesticides was carried outby Gas Chromatography-Mass Spectrometry (GC-MS) working in the Selected Ion Monitoring (SIM) mode and therecoveries ranged from 75 to 102% at two spiking levels for 6 replicates.
Highlights
The outburst of technological development and the continuously increasing population have resulted in enlarged production of basic agricultural products whose production and provision is associated with chemicals of organic origin applicable in cultivation
Good linearity of the response was found at specific concentration range indicated in Table 1, with the respective correlation coefficient (r2) for each pesticide
The limits of detection (LOD) was defined as 3.3(Sy/x)/a and the LOQ as 10(Sy/x)/a, where Sy/x represents the residual standard deviation and a is the slope of the calibration plot
Summary
The outburst of technological development and the continuously increasing population have resulted in enlarged production of basic agricultural products whose production and provision is associated with chemicals of organic origin applicable in cultivation. The latter, which is a result of human activities on land, are very persistent, and through the aquifer, end up into the aquatic environment. H., Kanan et al 1994, Parimi et al 2006) As hydrophobic compounds they display high affinity for lipids and a tendency to accumulate in marine organisms. They bio-accumulate through the food chain causing damages to the human health and environment
