2009年采用气相色谱-质谱联用分析方法，测定了天津市城郊农田、蔬菜、果园和荒地土壤中6种邻苯二甲酸酯（PAEs）的分布。结果表明，PAEs总量变化范围为0.05 ~ 10.4 μ g(-1)，中位数为0.32 μ g（-1）。邻苯二甲酸二（2-乙基己基）和邻苯二甲酸二正丁酯是最丰富的种类。4种土壤中PAEs浓度依次为蔬菜土、荒地土、农田土、果园土、果园土。与其他研究相比，PAEs在较发达地区的含量较高。农用地膜能提高土壤中PAEs的含量。主成分分析表明，化妆品、个人护理用品和增塑剂是天津近郊土壤中PAEs的重要来源。随着城市化进程的推进，出现了大量的固体废弃物，城郊荒地土壤中PAEs含量较高，应引起高度重视。(c) 2012 Elsevier Ltd.版权所有。
The distribution of six priority phthalic acid esters (PAEs) in suburban farmland, vegetable, orchard and wasteland soils of Tianjin were obtained with gas chromatography-mass spectrometer analysis in 2009. Results showed that total PAEs varied from 0.05 to 10.4 mu g g(-1), with the median value as 0.32 mu g g(-1). Di-(2-ethylhexyl) phthalate and di-n-butyl phthalate are most abundant species. PAEs concentrations for the four types of soils exhibited decreasing order as vegetable soil > wasteland soil > farmland soil > orchard soil. PAEs exhibited elevated levels in more developed regions when compared with other studies. The agricultural plastic film could elevate the PAEs contents in soils. Principal component analysis indicated the emission from cosmetics and personal care products and plasticizers were important sources for PAEs in suburban soils in Tianjin. The higher PAEs contents in wasteland soils from suburban area should be paid more attention owing to large amounts of solid wastes appeared with the ongoing urbanization. (c) 2012 Elsevier Ltd.
