This study explored occurrence of phthalic acid esters (PAEs) in protected agriculture soils and assessed their potential health risks to humans. Results showed that DEHP and DBP were the most abundant PAEs congeners, with mean concentrations of 318.68 μg/kg and 137.56 μg/kg, respectively. DOP and BBP concentrations were relatively low, and DMP and DEP were not detected in all samples. DBP concentrations were higher than the allowable concentration standard value. Additionally, soil pH and organic matter were key environmental parameters which may play the vital roles to the occurrence of organic pollutants. Heath risk assessment results indicated that dermal contact was the predominant human exposure route under non-dietary conditions, and children obtained higher health risk scores than adults. In summary, the overall health risk scores were at an acceptable level. These results provide insights for assessing soil environmental safety and ecological risks in protected agricultural soil.

受保护的农业土壤中邻苯二甲酸酯 (PAE) 的存在及其对人类健康暴露的影响

本研究探讨了受保护农业土壤中邻苯二甲酸酯 (PAE) 的发生情况,并评估了它们对人类的潜在健康风险。结果表明,DEHP和DBP是最丰富的PAEs同源物,平均浓度分别为318.68 μg/kg和137.56 μg/kg。DOP 和 BBP 浓度相对较低,所有样品中均未检测到 DMP 和 DEP。DBP浓度高于允许浓度标准值。此外,土壤pH和有机质是关键的环境参数,可能对有机污染物的发生起重要作用。健康风险评估结果表明,皮肤接触是非饮食条件下的主要人体接触途径,儿童获得的健康风险评分高于成人。总之,总体健康风险评分处于可接受的水平。这些结果为评估受保护的农业土壤中的土壤环境安全和生态风险提供了见解。
