title: [Extraction of organochlorine pesticides using ASE from wastewater irrigated agricultural soil].
abstract: The extraction efficiency of accelerated solvent extraction (ASE) was studied for organochlorine pesticide residuals in soil and compared with that of Soxhlet. The results showed that the efficiency of ASE was generally better than Soxhlet when used for DDT measurement, and equivalent to Soxhlet for BHCs. With ASE, organochlorine pesticide residues were detected in wastewater irrigated and non-wastewater irrigated soils from Tianjin. alpha-BHC, beta-BHC, delta-BHC, gamma-BHC, p,p'-DDE, p,p'-DDD, p,p'-DDT, o,p'-DDT ranged from 7.5 to 71.1 ng/g in wastewater irrigated vegetable and maize field and from 3.0 to 16.5 ng/g in wastewater irrigated paddy field. The eight pesticide residues from non-wastewater irrigated vegetable and maize field was in a range of 3.1-17.6 ng/g.
