基于风险的Football组合法在筛选农用地优先控制酞酸酯类污染物的应用

Risk-based Football Combination Method for Screening Priority Control Phthalates in Agricultural Land

为探索建立农用地优先管控酞酸酯类有毒有害化学物质的筛选方法,基于Football组合法开展了相关研究。结果表明,邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二(2-乙基己基)酯(DEHP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸丁基苄基酯(BBP)和邻苯二甲酸二乙酯(DEP)等5 种酞酸酯类内源污染物潜在风险较高,将筛选结果与国内外管控化学物质名单进行比较分析,表明Football组合法可用于筛选农用地优先控制酞酸酯类有毒有害物质。

In order to explore the establishment of a priority method for the control of phytate-like, toxic and hazardous chemicals in agricultural land, a screening study was carried out on the precedent-controlled phthalate esters in agricultural land with the Football combination method. The results show that five kinds of phthalate endogenous pollutants including dibutyl phthalate (DBP), di(2-ethylhexyl) phthalate (DEHP), diisobutyl phthalate (DIBP), benzylbutyl phthalate (BBP) and diethyl phthalate (DEP) have high potential risk. The screening results indicate that the Football combination method can be used to screen the precedent-controlled phthalate esters in the agricultural land through comparing with the list of domestic and international controlled chemical substances.
