Thirteen samples of seawater were collected from Yellow Sea and East China Sea near Qingdao, Lianyungang, and Xiamen, China. They were analyzed for halogenated organophosphorus flame retardants (OPFRs). The compounds selected for detection were Tris(2-chloroethyl) phosphate (TCEP), Tris(2-chloroisopropyl) phosphate (TCPP), Tris (1,3-dichloro-2-propyl) phosphate (TDCPP), and Tris(2,3-dibromopropyl) phosphate (TDBPP). The total concentrations ranged from 91.87 to 1392 ng/L and the mean concentrations of these four chemicals were 134.44, 84.12, 109.28, and 96.70 ng/L, respectively. TCEP exhibited the highest concentrations, although concentrations of TCPP and TDCPP were also fairly high in Lianyungang and Xiamen. Generally, Lianyungang was the most heavily polluted district, with very high concentrations of TCEP at LYG-2 (550.54 ng/L) and LYG-4 (617.92 ng/L). The main sources of halogenated OPFRs were municipal and industrial effluents of wastewater treatment plants in the nearby economic and industrial zones.
从中国青岛、连云港和厦门附近的黄海和东海采集了13份海水样本。对其进行了卤代有机磷阻燃剂（OPFRs）分析。选择检测的化合物为磷酸三（2-氯乙基）酯（TCEP）、磷酸三（2-氯异丙基）酯（TCPP）、磷酸三（1,3-二氯-2-丙基）酯（TDCPP）和磷酸三（2,3-二溴丙基）酯（TDBPP）。总浓度范围为91.87至1392 ng/L，这四种化学物质的平均浓度分别为134.44、84.12、109.28和96.70 ng/L。TCEP的浓度最高，不过在连云港和厦门，TCPP和TDCPP的浓度也相当高。总体而言，连云港是污染最严重的地区，在LYG-2（550.54 ng/L）和LYG-4（617.92 ng/L）处TCEP浓度非常高。卤代OPFRs的主要来源是附近经济和工业区污水处理厂的城市和工业废水排放。
