This study assessed the tissue distribution, dietary intake, and potential health risks of eight OPPs in Pomadasys commersonnii (Spotted grunter) and Mugil cephalus (Flathead mullet) from the Sundays and Swartkops estuaries in South Africa. The highest concentration in fish tissues was found in muscles of M. cephalus (178 ± 80.4 ng/g ww) and P. commersonnii (591 ± 280 ng/g ww) from Sundays Estuary. The ∑OPPs concentration in muscles from both fish species was higher in muscles than in the gills with fenitrothion dominating the distribution profile. Results from the path analysis indicate that lipid, weights, and length of the fish species do not influence the concentration of OPPs in the studied fish species. The calculated hazard ratios, which represent the non-carcinogenic risks, were less than one for all OPPs, indicating that the concentration of OPPs detected in fish muscles had negligible consequences on human health.
本研究评估了南非桑兹和斯瓦特克普斯河口的斑点鲈（Pomadasys commersonnii）和褐鲻（Mugil cephalus）中 8 种有机磷农药（OPPs）的组织分布、膳食摄入和潜在健康风险。鱼类组织中浓度最高的是桑兹河口褐鲻的肌肉（178 ± 80.4ng/g 鲜重）和斑点鲈的肌肉（591 ± 280ng/g 鲜重）。两种鱼类肌肉中的∑OPPs 浓度均高于鳃，其中 fenitrothion 主导着分布特征。路径分析的结果表明，鱼类的脂质、体重和长度均不会影响研究鱼类中 OPPs 的浓度。所有 OPPs 的危害比均小于 1，表明在鱼肌肉中检测到的 OPPs 浓度对人类健康的影响可以忽略不计。
