摘要:

分别采用微波萃取-气相色谱/质谱法、加速溶剂萃取提取-液相色谱/质谱法对采自太滆运河5个沉积物样品中的6种邻苯二甲酸酯类（PAEs）、13种多溴联苯醚（PBDEs）和9种有机磷酸酯（OPEs）的质量比及分布进行研究。结果表明，所有样品中均检测到PAEs、PBDEs和OPEs（以总量计），其总质量比分别为1.99～6.90μg/g,47~572和17.1~69.7 ng/g；十溴联苯醚（BDE-209）和磷酸三异辛酯（TEHP）分别是质量比最高的PBDEs和OPEs；对于PAEs，入太湖点位处邻苯二甲酸二（2-乙基己基）酯（DEHP）质量比较高，其余点位则是邻苯二甲酸二正丁酯（DBP）质量比较高；ω（PAEs）、ω（PBDEs）和ω（OPEs）两两间线性相关性较好，指示其来源相同；下游沉积物中污染物的质量比均高于上游，沿岸生产、生活中增塑剂和阻燃剂对太湖的污染应引起更多关注。

Abstract:

Levels and distributions of 6 phthalate esters (PAEs), 13 polybrominated diphenyl ethers (PBDEs) and 9 organophosphate esters (OPEs) in 5 sediment samples collected from Taige Canal were investigated. The samples for PAEs and PBDEs analysis were microwave extracted, and then determined by gas chromatography mass spectrometry, while the samples for OPEs analysis were accelerated solvent extracted followed by liquid chromatography mass spectrometry. PAEs, PBDEs and OPEs were detected in all the sediments at concentrations ranging from 1.99~6.90 μg/g，47~572 and 17.1~69.7 ng/g. Decabrominated diphenyl ether (BDE-209) and tris(2 ethylhexyl) phosphate (TEHP) were the dominant compounds for the detected PBDEs and OPEs, respectively. As for PAEs, Di n butyl phthalate (DBP) was the main compound, except in the site of estuarine to Taihu Lake, where di(2 ethylhexyl) Phthalate（DEHP) had the highest concentration. Significant correlation between the concentrations of PAEs and PBDEs, PAEs and OPEs, PBDEs and OPEs was observed, indicating the same source for three kinds of pollutants. The levels of all the pollutants in the downstream of the Taige Canal were higher than those in the upstream, plasticizer and flame retardants pollution to Taihu Lake from production and life activities should be paid attention.
