| Abstract | In order to assess and analyze the pollution level and distribution character of phthalic acid esteis (PAEs) in soils of Leizhou peninsula, south of China, 71 topsoil samples and 3 soil profile samples were collected from 4 functional agriculture areas of Leizhou peninsula, 16 PAEs including dimethyl phthalate(DMP), diethyl phthalate(DEP), diisobutyl phthalate(DIP), di-n-butyl phthalate(DnBP), bis(methoxyethyl) phthalate (BMP), hexy1-2-ethylhexyl phthalate(HEP),Bis(ethoxyethyl)phthalate (BEHP), di-amyl phthalate(DAP), di-n-hexyl phthalate (DHP), butylbenzyl phthalate(BBP), bis(4-methyl,2-pentyl)phthalate(BMPP), bis(2-n-butoxyethyl)phthalate(BnBP), dicyclohexyl phthalate (DCP), di-n-octyl phthalate(DnOP), di-nonyl phthalate(DnP) and di-2-ethylhexyl) phthalate(DEHP) were determined by gas chromatography- FID detector (GC-FID). Total contents of the 16 PAE compounds( capital sigma PAEs) in all top soils ranged from ND to 5452.7 mu g times kg super(-1), with the average 736.5 mu g times kg super(-1). Among 6 U.S.EPA priority pollutants of PAEs, the contents of DMP, DEP and DnBP in all top soils exceeded the control limits of PAEs in American soil by 1.4%, 45.07% and 91.55% respectively, but the contents of DEHP, DnOP and BBP were less than the control limits. The pollution level of PAEs in topsoil of Leizhou peninsula was lower than that reported in the country. The main components of PAE compounds in soils of Leizhou peninsula were DnBP, DEHP, DIP, BEHP and DAP, and their averaged concentrations in soils was 282.3, 140.7, 92.55, 79.63 and 45.94 mu g times kg super(-1) respectively. Although distribution of capital sigma PAEs in the samples was not well defined, the data suggested the order of pollution potential was sugarcane soil>paddy field>pot garden>fruit garden among 4 functional agriculture areas, and that was Leizhou>Xiashan>Chikan>Wuchuan>Xuwen>Lianjiang>Mazhang>Potou>Suixi among 9 districts of Leizhou peninsula. The contents of capital sigma PAEs and DEHP decreased with the depth of soil profile, but when the contents of DnBP were higher, the contents of capital sigma PAEs and DEHPy increased with depth earlier then decreased. |
