Polycyclic aromatic hydrocarbons in the coastal sea water, the surface sediment and Mudskipper Boleophthalmus dussumieri from coastal areas of the Persian Gulf: source investigation, composition patte

Background: persian gulf is an exposed and stressed area as a result of oil pollution and other fossil fuelscontaining pahs. the susceptibility of using mudskippers to monitor marine pollution, like pahs, points to the factthat mudskippers are able to accumulate and record the pahs presented in the coastal environments.methods: polycyclic aromatic hydrocarbons (pahs) were examined in the coastal waters, the sediments and biota(i.e., boleophthalmus dussumieri) along the coast of the persian gulf. pahs concentrations were measured with hplcmethod.results: total pah concentrations in the sea water, the sediments, the liver and the gill tissues ranged between0.80-18.34 ?g/l, 113.50-3384.34 ng g?1 (d w), 3.99-46.64 ng g?1 (d w) and 3.11-17.76 ng g?1 (d w), respectively. pahsdistribution patterns in the sediment and the liver tissue samples were dominated by three-and four-ring structureswhereas two-and three-rings were dominated in the water and the gill.conclusions: this finding revealed a negative eco-risk effects occasionally occur in this area. the higher presenceof low condensate ring structures reflected a predominant origin of petrogenic and some cases of pyrolitic sources.
