英文摘要:
Surface sediments (n�=�17) were collected from 6 sites located in the coasts of the Bushehr Peninsula. ∑16PAH concentrations were in the range of 285.9–1288�ng�g−�1dw and the sediments were moderately polluted. Py, Ph, B(a)A and Flu showed >�70% of the detected values in order of the mentioned rank. 4-ring PAHs were the dominant compounds and the molecular ratios presented the dominant pyrolytic source. The toxicity of PAHs for sediment dwelling life was averagely equivalent to occurrence of 0.08�ng�g−�1of Dioxin in dw of the examined sediments. The evaluated narcotic potential (confidence level of 99%) was 0.027–3.04 and upper part of the Bushehr Peninsula, where the human population is more concentrated, showed more narcotic potential. ∑�n-alkane concentrations (n-C15�−�n-C32) were in the range of 3.10–35.6�μg�g−�1dw. The dominant distribution of even carbon number n-alkanes was traced back to a possibly autochthonous source. � 2016 Elsevier Ltd
