title: Distribution of PAHs in different compartment of creek ecosystem: Ecotoxicological concern and human health risk.
abstract: We report levels of polycyclic aromatic hydrocarbons in sediment, seawater, fish and crab samples from Thane creek, India. Concentrations of sixteen USEPA PAH in sediments varies from 874 to 1925ngg-1, dry weight (dw) in winter, between 219-495ngg-1in summer. In seawater Σ16PAHs concentration during winter was recorded 706±193ngL-1, and during summer 337±79ngL-1. Total concentrations of PAHs in consumable portion of lizard fish, bombay duck and crab were found 156.8±18 and 122±24.5ngg-1, 117.4±17.65ngg-1and 95.8±16.2ngg-1, 348±94.5 and 95.62±31.9ngg-1wet weight (ww) in summer and winter respectively. PAHs concentration were compared with sediments quality guidelines viz. ERL-ERM, TEL-PEL indexes for finding ecotoxicological risk on marine organism. The ILCR values were above public screening criteria for carcinogens.
