The concentrations and spatial distribution of 14 organophosphorus flame retardants (OPFRs) and plasticizers were studied in aquatic environments of China, namely, the Pearl River Delta (PRD), South China Sea (SCS) and Yellow River Estuary (YRE), as well as Tokyo Bay (TB) in Japan. These locations were characterized by different levels of socioeconomic development and human activities. The spatial pattern of OPFRs revealed their ubiquity along the coasts of China and Japan; the concentrations ranged from 15 to 1790, 1 to 147, 253 to 1720, and 107 to 284 ng L in the PRD, SCS, YRE and TB, respectively. The most frequently detected OPFR was triethyl phosphate (TEP), followed by triphenylphosphine oxide (TPPO) and tris(2-chloroethyl) phosphate (TCEP). A positive relationship (R = 0.668, p = 0.004) was observed between OPFR contamination and socioeconomic activity, measured by gross domestic product (GDP) per capita, for the studied cities in China and Japan. The results suggest that an increase in manufacturing and construction activities in the studied areas may aggravate coastal contamination with OPFRs. The potential threat to aquatic organisms from exposure to TCEP, a suspected carcinogen, was revealed by the hazard quotient (HQ) and probabilistic assessments. Further investigation of OPFR exposure in the aquatic environment of China is urgently required.
研究了中国珠江三角洲（PRD）、南海（SCS）和黄河口（YRE）以及日本东京湾（TB）等水域中 14 种有机磷阻燃剂（OPFRs）和增塑剂的浓度和空间分布。这些地点的特点是社会经济发展水平和人类活动水平不同。OPFRs 的空间格局表明它们在中国和日本沿海地区普遍存在；浓度范围分别为 15 至 1790、1 至 147、253 至 1720 和 107 至 284ng/L。最常检测到的 OPFR 是三乙基磷酸酯（TEP），其次是三苯基氧化膦（TPPO）和三（2-氯乙基）磷酸酯（TCEP）。OPFR 污染与社会经济活动之间存在正相关关系（R=0.668，p=0.004），以人均国内生产总值（GDP）衡量，研究中国和日本的城市。结果表明，研究地区制造业和建筑业活动的增加可能会加剧沿海地区 OPFRs 的污染。危害商（HQ）和概率评估显示，三氯乙烯（TCEP）作为一种疑似致癌物质，可能对水生生物造成威胁。迫切需要进一步调查中国水生环境中 OPFR 的暴露情况。
