Toxicity of dispersant application: Biomarkers responses in gills of juvenile golden grey mullet (Liza aurata)

摘要: Dispersant use in nearshore areas is likely to increase the exposure of aquatic organisms petroleum. To measure toxicity this controversial response technique, golden grey mullets (Liza aurata) were exposed mechanically dispersed oil, chemically dispersant alone seawater, water-soluble fraction oil and seawater as a control treatment. Several biomarkers assessed gills (enzymatic antioxidant activities, glutathione content, lipid peroxidation) gallbladder (polycylic aromatic hydrocarbons metabolites). The significant differences between water soluble highlight environmental risk disperse an slick when containment recovery can be conducted. lack significance suggests that application no more toxic than natural dispersion slick. results study are interest order establish policies areas.
