| 摘 要： | 目的 探索邻苯二甲酸酯（PAEs）在河南植烟土壤中的污染状况。 方法 采集了7个县区203份耕层土壤样品，气相色谱质谱法分析了邻苯二甲酸二甲酯（DMP）、邻苯二甲酸正二丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸丁基苄酯（BBP）和邻苯二甲酸正二辛酯（DnOP）等6类PAEs含量。 结果 （1）河南植烟土壤PAEs污染物检出频率较高，以DBP、DEHP污染物为主，均值分别为0.348 mg/kg和0.131 mg/kg。参考美国土壤PAEs控制标准，河南植烟土壤DBP超标率达97.8%，DMP超标率为5.42%，6种单因子PAEs含量均未超过其治理标准。（2）不同县区之间土壤PAEs污染程度不同；相比卢氏县，豫中地区叶县、建安、郏县、襄县的植烟土壤DBP单因子及PAEs综合污染指数相对较高。（3）土壤DBP含量与土壤pH值呈显著负相关，与土壤蛋白含量呈极显著正相关。（4）与0~3年烤烟种植年限相比，种植4年后的植烟土壤DMP、DBP和PAEs总量显著升高。

| Abstract: | To investigate the pollution characteristics of phthalate esters (PAEs) in tobacco field soil in Henan Province, 203 soil samples were collected from 7 counties and six PAEs compounds including dimethyl phthalate (DMP), dibutyl phthalate (DBP), di(2-ethylhexyl)phthalate (DEHP), diethyl phthalate (DEP), butyl benzyl phthalate (BBP), di-n-octyl phthalate (DnOP) in samples were analyzed using gas chromatography-mass spectrometry. The results showed that the detection frequency of PAEs in soil was high; DBP and DEHP were the main pollutants, with the average contents of 0.348 mg/kg and 0.131 mg/kg, respectively. According to the PAEs control standard of the USA, the over-standard rate of DBP and DMP was 97.8% and 5.42% in tobacco field soil of Henan province, respectively. Furthermore, there were significant differences of PAEs concentrations among 7 counties and 35 towns. DBP single-factor pollution index and PAEs comprehensive pollution index of tobacco fields were relatively higher in Yexian, Jian'an, Jiaxian and Xiangxian counties than in Lushi county. Soil DBP content was negatively correlated with pH value but positively correlated with soil protein index. The concentrations of DMP, DBP and PAEs in soil increased significantly after 4 years of continuous tobacco cropping compared with those in soil after 0-3 years of tobacco cropping. |
