摘要:对天津市11个采样点的空气颗粒物和土壤样品进行采样调查,采用气相色谱/质谱联用仪分析样品中15种酞酸酯类化合物(PAEs)的含量.结果表明,11个采样点空气颗粒物样品中总酞酸酯类化合物(TPAEs)以体积计质量浓度为90.87~1 355.70 ng/m~3,以质量计质量浓度为783.84~8 712.37 mg/kg,土壤中TPAEs质量浓度为0.53~2.53 mg/kg.邻苯二甲酸二丁酯(DBP)与邻苯二甲酸二(2-乙基己基)酯(DEHP)是空气颗粒物和土壤样品中的主要污染物.土壤与空气颗粒物中TPAEs和DBP存在相关关系,Pearson相关系数分别为0.825和0.864(双尾检验,显著性水平0.01),且空气颗粒物中各种PAEs浓度为土壤PAEs浓度的数百至数万倍,说明空气沉降可能是土壤PAEs污染的主要原因之一.Abstract:Atmospheric particle and soil were sampled from 11 sites of Tianjin. 15 kinds of phthalic acid ester (PAEs) in these samples were determined by gas chromatography-mass spectrometry (GC/MS). Total contents of the 15 PAEs compounds(TPAEs)in 11 atmospheric particles samples were calculated, with the volume concentration ranged from 90.87 to 1 355.70 ng/m~3 and mass concentration ranged from 783.84 to 8 712.37 mg/kg. The mass concentration of TPAEs in soil samples ranged from 0.53 to 2.53 mg/kg. The dominant phthalates were DBP and DEHP in both atmospheric particles and soils. The correlation of PAEs in atmospheric particles and soils was ana-lyzed, and the result demonstrated that TPAEs and DBP had significant correlation with the coefficient of 0.825 and 0.864 (two-tailed test, significant at the 0.01 level). The content of PAEs in atmospheric particles could thousandstimes higher than that in soil, which means atmospheric particles sedimentation might be one of reason for PAEs pol-lution in soil.水利论文 Y_1Qs}
