对来自斯里兰卡附近印度洋的 29 种可食用水生物种和来自日本附近太平洋的 10 种水生物种中的 75 种污染物进行了调查，其中包括氯化/溴化/母体多环芳烃 (Cl/Br/PAH)。来自印度洋的样品中总 ClPAH 和 BrPAH 的浓度分别为 2.6-57 和 0.30-9.5 ng/g（干重），来自太平洋的样品中总 ClPAH 和 BrPAH 的浓度分别为 0.35-18 和 0.03-3.3 ng/g（干重）。比较样品中 Cl/BrPAH 的分布，氯化芘和溴化芘的同系物是主要成分，增强了印度洋近海中上层环境样品的生物放大潜力。通过摄入水生生物中的目标来估算的终生癌症风险增量表明，大约三分之一的研究生物超出了斯里兰卡人可接受的风险水平。
Seventy-five contaminants including chlorinated/brominated/parent polycyclic aromatic hydrocarbons (Cl/Br/ PAHs) were investigated in 29 edible aquatic species from the Indian Ocean near Sri Lanka and 10 species from the Pacific Ocean near Japan. Concentrations of total ClPAHs and BrPAHs in the samples were 2.6-57 and 0.30-9.5 ng/g-dry weight from the Indian Ocean, and 0.35-18 and 0.03-3.3 ng/g-dry weight from the Pacific Ocean, respectively. Comparing the profiles of Cl/BrPAHs among the samples, congeners of chlorinated and brominated pyrene were predominant components and enhanced the potential for biomagnification in the sample from the off-shore pelagic environment in the Indian Ocean. The incremental lifetime cancer risks estimated by intake of the targets in consuming aquatic organisms showed that approximately one-third of studied organisms exceeded the acceptable risk level for Sri Lankans.
