Abstract

In this study, concentrations of 16 PAHs (polycyclic aromatic hydrocarbons) have been determined in surface sediments from Gökçeada being the largest island of Turkey and located in the North Aegean Sea, during winter, spring, summer, and fall seasons in 2017. The main object of this study is to understand the levels, seasonal distribution, and the origins of PAHs in the sediments of Gökçeada. During the sampling period, the total PAH (TPAH − Σ₁₆PAH) values varied between 26 and 5408.7 ng/g dw. TPAH values in winter season have been found considerably higher due to residential heating. Besides, the origins of PAH pollution were investigated by using certain PAH ratios. The source of the pollution at all stations during the sampling period was found to be both petrogenic and pyrolytic origin so far as to the phenanthrene/anthracene (PHE/AN) and benzo(a)anthracene/chrysene (BaA/CHR) ratios.

摘要

在这项研究中，在2017年的冬季，春季，夏季和秋季，位于土耳其最大的岛屿Gökçeada的地表沉积物中确定了16种PAHs（多环芳烃）的浓度。这项研究的目的是了解Gökçeada沉积物中PAHs的水平，季节分布和成因。采样期间，总的PAH（TPAH - Σ ₁₆PAH）值在26至5408.7 ng / g dw之间变化。由于住宅取暖，冬季的TPAH值已大大提高。此外，通过使用一定比例的多环芳烃来调查多环芳烃污染的起源。就菲/蒽（PHE / AN）和苯并（a）蒽/丙烯（BaA / CHR）的比例而言，在采样期间所有站点的污染源均被发现是成因和热解的。
