First polychlorinated biphenyls (PCBs) monitoring in seawater, surface sediments and marine fish communities of the Persian Gulf: Distribution, levels, congener profile and health risk assessment.

摘要: Abstract Polychlorinated biphenyls (PCBs) are persistent organic pollutants that, due to their high toxicity, lipophilic property and widespread dispersal in the global environment, present a danger for human health ecological systems. Although inventory use of PCBs extensively reported worldwide, status Iran is still unknown. In this study, concentrations were determined environmental matrices five commercially important fish species from Larak coral Island, Persian Gulf, Iran, winter summer 2015. A positive correlation was found among levels congeners profiles seawater (0.97–3.10 ng L−1), surface sediments (2.95–7.95 ng g−1dw) samples (7.20–90.19 ng g−1dw), indicating as suitable bioindicator contamination. all matrices, contribution light medium chlorinated detected both seasons. fish, higher sexes seasons liver kidney than other tissues (skin, gonad, muscle) lipid content lipophilicity.
