Abstract：
The study investigates the pollution characteristics of 16 priority PAHs, accumulated in copepods from a major fishing harbour and its adjacent coastal waters of Veraval, west coast of India. The total PAH accumulation is in the range of 922.16-27,807.49 ng g-1 dw, with the mean concentration of 5776.59 ng g-1 dw. High concentrations of PAHs were present in the copepod samples from inside the harbour. Notably, there was no significant correlation between the lipid content of copepods and the accumulation of PAHs. The molecular diagnostic ratio method (MDR) indicates that the PAH sources are petrogenic in origin, while principal component analysis (PCA) points to petroleum, coal combustion and vehicular emission sources. Total cancerous PAHs (C-PAHs) in the study area dominate by 40% of the total PAHs identified; moreover, the bioaccumulation factor (BAF) is very high in the offshore area, which is also a fishing ground. The global relevance and magnitude of the present study in the Veraval, one of the prime seafood exporting hubs in India, should be dealt with utmost avidity as the accumulation status of PAHs in the zooplankton has never been explored in the Indian coastal waters. Moreover, the current study gives the foremost data on the bioaccumulation status of PAHs in copepods from the tropical waters of India.
摘要：
本研究调查了16种优先多环芳烃的污染特征，积聚在主要渔港及其邻近的Veraval沿海水域的co足类动物中，印度西海岸。PAH的总积累量在922.16-27,807.49ngg-1dw范围内，平均浓度为5776.59ngg-1dw。港口内的co足类动物样品中存在高浓度的PAHs。值得注意的是,co足类的脂质含量与PAHs的积累之间没有显着相关性。分子诊断比率法(MDR)表明PAH来源是岩石来源的，而主成分分析(PCA)指向石油，煤燃烧和车辆排放源。研究区域中的癌性PAHs（C-PAHs）占已确定的PAHs总数的40％；此外，近海区域的生物累积因子(BAF)非常高，这也是一个渔场。本研究在Veraval的全球相关性和规模，印度主要的海鲜出口中心之一，由于从未在印度沿海水域探索过浮游动物中多环芳烃的积累状况，因此应以最大的亲和力来处理。此外，当前的研究提供了有关印度热带水域co足类中多环芳烃生物积累状况的最重要数据。
