This study utilized a comprehensive screening strategy to thoroughly investigate the species-specific distribution and tissue-specific distribution of potential organophosphate esters (OPEs) in 15 species of wild freshwater fish (n = 109). A total of 26 OPEs were identified, with tris(2-butoxyethyl) phosphate being the predominant OPE. The concentrations of OPEs ranged from 7.80 to 495 ng/g wet weight. No direct correlation was observed between OPE levels and fish body size. Feeding habits play a significant role in the accumulation levels of OPEs in fish species. Carnivorous fish exhibited the highest mean OPE concentration, followed by omnivorous fish, with herbivorous fish having the lowest concentration. Among all tissues and organs of fish, the brain exhibited the most elevated concentration of OPEs. The health risk assessment across all age groups based on Monte Carlo simulations revealed that children were at a high risk of exposure to OPEs through the consumption of wild freshwater fish.
本研究采用综合筛选策略，对15种野生淡水鱼（n = 109）中潜在有机磷酸酯（OPEs）的物种特异性分布和组织特异性分布进行了全面调查。共鉴定出26种OPEs，其中磷酸三（2-丁氧基乙基）酯是主要的OPE。OPEs的浓度范围为7.80至495纳克/克湿重。未观察到OPE水平与鱼体大小之间存在直接相关性。摄食习惯在鱼类OPEs的积累水平中起着重要作用。肉食性鱼类的平均OPE浓度最高，其次是杂食性鱼类，草食性鱼类的浓度最低。在鱼的所有组织和器官中，大脑中OPEs的浓度最高。基于蒙特卡洛模拟的所有年龄组健康风险评估显示，儿童通过食用野生淡水鱼接触OPEs的风险很高。
