Abstract: 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.
