黄河流域中上游邻苯二甲酸酯的排放特征及生态风险评价
Emission characteristics and ecological risk assessment of phthalate esters in the upper and middle reaches of the Yellow River Basin
摘要
Abstract
Concentrations and emission characteristics of 7 phthalate esters(PAEs)were analyzed in surface water from 4 discharge outlets of coal chemical industry parks and their upstream and downstream sections in the middle and upper reaches of the Yellow River Basin.The results showed that the concentration range of PAEs in surface water of the middle and upper reaches of the Yellow River Basin was 585～5 534 ng/L,which was mainly dominated by di(2-ethylhexyl)phthalate(DEHP).The concentration range of PAEs in the 4 discharge outlets of coal chemical industry parks was 745～26 801 ng/L,mainly dominated by dibutyl phthalate(DBP)and DEHP.The total concentration of PAEs exhibited a distribution characteristic of upstream of discharge outlets(1 113 ng/L)<downstream of discharge outlets(1 769 ng/L)<discharge outlets(8 341 ng/L).It was showed that the discharge of wastewater from coal chemical industry parks made a certain contribution to the increase in PAEs concentrations in the downstream water bodies,with DBP and DEHP as the main contributing components.It was revealed by the ecological risk assessment results that DEHP and DBP exhibited high and medium ecological risks respectively in the key sections of the middle and upper reaches of the Yellow River Basin.Among them,the ecological risk in the Wuhai section was relatively high,which required special attention.关键词
