The study aims to investigate the source and concentration of PAH fractions in the reef sediments of the Vembar group of Islands, Gulf of Mannar, India. The concentration of PAHs ranged from 0.36 to 15.98 ng/g. The reef environment was less contaminated with low-molecular-weight PAH fractions. The accumulation of the LMW-PAH fraction was very less, whereas the HMW fraction was derived from pyrolytic sources. The level of low and high molecular weight PAHs was lower than the level of Effective Range Median (ERM) and Effective Range Low (ERL).The calculated total TEQ value ranged from ND to 10.24 ng/g in the reef sediments.
本研究旨在调查印度马纳尔湾文巴尔群岛珊瑚礁沉积物中多环芳烃（PAH）各组分的来源和浓度。多环芳烃浓度范围为 0.36 至 15.98 纳克/克。珊瑚礁环境受低分子量 PAH 组分污染较轻。低分子量 PAH 组分的积累非常少，而高分子量 PAH 组分则来自热解源。低分子量和高分子量 PAH 的水平均低于有效范围中值（ERM）和有效范围低值（ERL）。在珊瑚礁沉积物中，计算得出的总等效毒性值范围从未检出到 10.24 纳克/克。
