The objective of this study was to evaluate the burden of environmental pollution by Polychlorinated Biphenyls (PCBs) and Organochlorine Pesticides (OCs) in two localities of Rio de Janeiro coast, through the determination of these levels in specimens of mullets and croakers collected from May to August 2008, at Guanabara Bay (GB) and from Araújo Island (AI), at Paraty Bay. Twenty three organochlorine pollutants were detected in croakers at GB and twenty in mullets and all PCBs congeners investigated in the study were present in the two species. Ratio ∑DDT/∑PCB of 1.4 shows an important contribution of agricultural residues in GB and p,p'-DDE/∑DDT of 0.1 demonstrates a reintroduction of DDT. Consumption of mullet may represent a risk to the health of fishermen families from GB, with average and maximum estimated daily intake of ∑DDT of 9.012μg/kg p.c. and 26,174μg/kg p.c., representing 45% and 131% of ADI established by WHO.
本研究旨在评估里约热内卢海岸两个地区的多氯联苯（PCBs）和有机氯农药（OCs）的环境污染负担，通过测定 2008 年 5 月至 8 月期间在瓜纳巴拉湾（GB）和帕拉蒂湾的阿劳若岛（AI）采集的鲻鱼和石首鱼样本中的这些污染物水平。在 GB 的石首鱼和在鲻鱼中检测到 23 种有机氯污染物，在所研究的所有 PCB 同系物中均存在。∑DDT/∑PCB 的比值为 1.4，表明农业残留物在 GB 中占有重要地位，p,p'-DDE/∑DDT 的比值为 0.1，表明滴滴涕的重新引入。GB 地区渔民家庭食用鲻鱼可能会对健康造成风险，∑DDT 的平均和最大估计日摄入量分别为 9.012μg/kg 体重和 26,174μg/kg 体重，分别占世界卫生组织（WHO）规定的日允许摄入量（ADI）的 45%和 131%。
