文摘	采用超声提取、固相萃取和气相色谱质谱联用(GC-MS)分析技术,测定了12个上海市政污水处理厂外排污泥中的8种常见有机磷酸酯(OPs)的浓度水平与分布特征.所有污泥样品中检出多种OPs分布,OPs总含量范围为138—778 ng·g~(-1) .主要污染物为三(1-氯-2-丙基)磷酸酯、三苯基磷酸酯、三-(2-氯乙基)磷酸酯(TCEP) ,浓度范围分别为LOD—206 ng·g~(-1)、8.82—52.9 ng·g~(-1)和7.12—65.7 ng·g~(-1) .研究结果表明,生活污水和工业废水是OPs重要释放来源.因其显著毒性效应和持久性,TCEP被欧美等国禁用,但本研究污泥中广泛检出且含量水平较高(7.12—65.7 ng·g~(-1)) ,结果折射其高历史残留或持续使用.
其他语种文摘	Occurrence and distribution of 8 widely used organophosphates esters (OPs) flame retardants /plasticizes were investigated in 12 sludge samples collected from the municipal wastewater treatment plants in Shanghai. These samples were pretreated via ultrasonic-assisted extraction,and separated via solid - phase extraction, subsequently analyzed by gas chromatography-mass spectrometry.Total concentrations of OPs ranged from 138 ng·g~(-1) to 778 ng·g~(-1) dry weight (mean at 297 ng·g~(-1)) in the sludges,with tris(2-chloroiso-propyl) phosphate,triphenyl phosphate,and tris (2-chloroethyl) phosphate (TCEP) as the dominant compounds,and their concentrations varied in the range of LOD—206 ng·g~(-1),8.82—52.9 ng·g~(-1) and 7.12—65.7 ng·g~(-1),respectively. The results indicated that OPs originated mainly from domestic sewage and industrial wastewater. Due to its obvious toxicities and strong persistency,TCEP was replaced by TCPP in European and USA. This compound was detected in all the sludge samples in the present study,which suggests that TCEP might be from past residue or still in use in the studied region.
