摘 要:采用分散液液微萃取-高效液相色譜法測定湘江株洲段水體中鄰苯二甲酸二甲酯(DMP)、鄰苯二甲酸二乙酯(DEP)、鄰苯二甲酸二正丁酯(DBP)和鄰苯二甲酸丁芐酯(BBP),利用正交實(shí)驗優(yōu)化了萃取條件,分析其污染水平分布,并進(jìn)行生態(tài)風(fēng)險評價(jià)。結果表明:4種鄰苯二甲酸酯類(lèi)物質(zhì)普遍檢出,∑PAEs的濃度范圍為22.39~27.4 μg/L,其中DBP為主要污染物。利用商值法對PAEs進(jìn)行生態(tài)風(fēng)險評價(jià),各種物質(zhì)均存在潛在生態(tài)風(fēng)險。 |

Abstract:A dispersive liquid-liquid microextraction/high performance liquid chromatograph method was developed for the simultaneous separation and determination of dimethyl phthalate,diethyl phthalate,dibutyl phthalate and benzyl butyl phthalate in the Zhuzhou part of Xiangjiang river water. Several factors that would affect recoveries of the compounds were studied with orthogonal design experiments. Concentration distribution and environmental risk assessment of the phthalic acid esters(PAEs)were evaluated. Results showed that the four PAEs were at a total concentration in the range of 22.39 μg/L to 27.4 μg/L. DBP was the main pollutant among the four PAEs. There exist potent risks for all the four PAEs according to the quotient risk evaluation results. |
Key words:PAEs;high performance liquid chromatograph;Xiangjiang River;risk evaluation |
