Abstract

Polychlorinated biphenyls have been determined in bivalve molluscs collected from OUALIDIA region in Morocco. It is a popular seaside resort of Moroccans, it is located 70 km south of El Jadida in the direction of Safi. Her Celebrity is due to its lagoon and oyster parks in September 2016. High-performance analytical techniques are required for the identification and quantification of these persistent organic pollutants. The objective of this study is to develop a multi-residual analysis method for polychlorinated biphenyls in bivalves by gas chromatography coupled with quadrupole triple mass spectrometry. A global protocol comprising a QuECHERS version of the extraction step followed by a step of purifying the extract obtained on a mixture of the adsorbents was carried out. The developed method allows the quantification of 7 polychlorinated biphenyls in "Oyster" bivalves. Linearity (R ≥ 0.995), specificity and selectivity, having an average efficiency greater than 70%, repeatability, reproducibility, accuracy, are checked. As a result, the potential of the developed method has been demonstrated.
