Abstract：The pollution characteristics, load and health risk assessment of 6 phthalate esters in soils from intensive vegetable fields in Nanjing, China were investigated by ultrasonic extraction combined with GC-MS and CalTOX model．The results showed that phthalate esters were detected in all soil samples, the total concentration of the 6PAEs ranged from 0.15~9.68mg/kg, with a mean of 2.21mg/kg. The dominant PAEs were di-n-butyl phthalate (DnBP), bis-(2-Ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DnOP) with 88.2%, 100% and 79.8% detection rate, the concentrations of which in soils ranged from n.d.~1.83, 0.02~9.03, n.d.~1.74mg/kg, respectively. There was no significant correlation among soil organic carbon, pH and PAEs concentrations. Total pollution load of PAEs was about 4.31kg/hm2 in the study area. Health risk assessment indicated that the risk of DnBP and DEHP was higher, and dermal contact was the primary exposure pathway to growers. Phthalate concentration, pollution load and health risks of intensive vegetable soils were significantly higher than these of surrounding outdoor vegetable soils.
