中文摘要:
      在珠海市3种不同类型农业区域内采集69个表层土壤和26个农产品样品,使用GC FID方法检测6种优先控制的邻苯二甲酸酯(PAEs)化合物,分析区域内PAEs的污染特征和对人体的健康风险。结果表明,农业土壤样品中Σ6PAEs值范围为未检出~1.21 mg/kg,平均值为0.40 mg/kg,空间分布上表现出中西部高、东部低的特征,土壤中PAEs以DnBP和DEP为主。农产品中∑6PAEs值范围为0.08 mg/kg~3.80 mg/kg,平均值为1.54 mg/kg,水稻、水果和蔬菜对PAEs的富集系数分别为6.23、2.50和2.80~7.06。成人和儿童PAEs的致癌风险分别为2.86×10-5和5.02×10-5,均高于人体致癌风险10-6水平。饮食摄入PAEs是致癌和非致癌风险的最大暴露途径,DEHP对人体两种风险的贡献最大。
英文摘要:
      69 topsoil samples and 26 farm products samples were collected from three different types of agricultural areas in Zhuhai. Six priority controlled PAEs were detected by GC-FID and their pollution characteristics and health risks to human beings were analyzed. The results indicated that Σ6PAEs in soil samples ranged from ND to 1.21 mg/kg, with an average of 0.40 mg/kg. The spatial distribution of PAEs had a characteristics of high in the central and western regions and low in the eastern regions. PAEs in soil were mainly DnBP and DEP. Σ6PAEs in farm products was 0.08 mg/kg ~ 3.80 mg/kg, with an average of 1.54 mg/kg. The enrichment coefficients of rice, fruit and vegetables for PAEs were 6.23, 2.50 and 2.80~7.06, respectively. The carcinogenic risk of PAEs for adults and children was 2.86×10-5 and 5.02×10-5, respectively, both were above human carcinogenic risk of 10-6. Dietary PAEs intake was the largest exposure route of carcinogenic and non-carcinogenic risks. DEHP contributed the most to the two human health risks.
