Effect of oil pollution on polychaete annelids in the Algerian East coast

abstract
This study was to assess the marine environment quality by hydrocarbon contamination along the east Algerian coasts using an approach based on biomarkers and hydrocarbon rate in the polychaete Perinereis cultrifera. Individuals were collected from two sites: Skikda considered as a polluted site and from El-Kala as a reference site. During this study two approaches have been maintained: the first was the analysis of physico-chemical parameters of the seawater, where no significant differences were recorded for temperature, salinity and DBO5, unlike the rate of dissolved O2, pH and oil content in the seawater. The second approach was devoted to measure the biomarkers activity of glutathione S-transferase as phase II enzyme in the polychaete P. cultrifera. This approach confirms that individuals from Skikda have been submitted to highly polluted environment.
