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 1925 ng g(-1), dry weight (dw) in winter, between 219-495 ng g(-1) in summer. In seawater E16 PAHs concentration during winter was recorded 7061193 ng L-1, and during summer 337 +/- 79 ng L. Total concentrations of PAHs in consumable portion of lizard fish, bombay duck and crab were found 156.8 +/- 118 and 122 +/- 124.5 ng g(-1), 117.4 +/- 117.65 ng g(-1) and 95.8116.2 ng g(-1), 348 +/- 194.5 and 95.62 +/- 131.9 ng g(-1) wet 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. (C) 2017 Elsevier B.V. All rights reserved.
