Application of the biomarker responses in scallop (Chlamys farreri) to assess metals and PAHs pollution in Jiaozhou Bay, China.
Scallops (Chlamys farreri) were collected at three sites in the Jiaozhou Bay, China in April and July 2007. The responses of biomarkers were evaluated for assessment of physiological status of scallops and pollution in the areas. Compared with site S1, the activity of aryl hydrocarbon hydroxylase was induced notably (P < 0.05) and glutathione S-transferase activity was inhibited significantly (P < 0.05) in S2 and S3. The levels of DNA alkaline unwinding, DNA protein crosslinks, protein carbonyl and lipid peroxidation were tested and indicated the oxidative stress situation of scallops. There was significant difference of biomarker levels between sampling seasons (P < 0.05), and between digestive gland and gill (P < 0.05). The results provided the reference data for multiple-pollution assessment in the marine environment and indicated that tissue type and seasons affect biomarkers, therefore these factors should be taken into consideration when biomarkers are used for environmental assessment purposes.
