DNA damage in mussels at sites in San Diego Bay

摘要: Abstract Identification and assessment of introduced other toxicants is crucial to any comprehensive study contaminants within the marine environment. The relationship between DNA single-strand breaks exposure organisms environmental was examined at sites in San Diego Bay, CA. A extent consequences contamination area Naval Station conducted summer 1995. addressed sources, distributions, concentrations, transport, sediment–water exchange, biological effects, degradation. effects portion (this paper) included contaminant bioaccumulation, organismal growth, determination using Comet assay. damage determined hemocytes collected from deployed resident mussels, Mytilus edulis , six stations around Diego. Deployed mussels were exposed on station for ∼30 days plastic mesh bags, placed 1 m above bottom. Hemocyte samples 0, 12, 32. It found that exhibiting extremes exposure, both highest lowest easily identified growth measurements. Sediment chemistry bioaccumulation data indicated, Hg, Cu, Zn, be most notable contaminants. assay, particular germ cell determinations, respond rapidly Results this an earlier 1993 suggest non-sediment associated observed one may have been result photoactivation accumulated PAHs.
