| Abstract: |
| The concentration and distribution of 6 phthalic acid esters(PAEs), listed as priority pollutants by United States Environmental Protection Agency, in 41 greenhouse agricultural soils in Xinmin(Shenyang City, China), were investigated by ultrasonic extraction combined with GC-FID. The results showed that the total concentration of the 6 PAEs(∑PAEs) in all the soil samples ranged from 0.52 mg·kg-1 to 1.73 mg·kg-1,with a mean of 0.94 mg·kg-1. Moreover, the ∑PAEs exceeded 1 mg·kg-1 in 32% of the tested soil samples. The two dominant PAEs were di-n-butyl phthalate(DnBP) and bis-(2-Ethylhexyl) phthalate(DEHP), which were detected in all the soil samples and accounted for 78% of the ∑PAEs. There were no significant correlations between the PAEs concentrations and the cropping period or the soil physiochemical characteristics(soil pH, organic matter, total nitrogen, and total phosphorus). |
