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.
本研究探讨了邻苯二甲酸酯（PAEs）在保护农业土壤中的存在情况，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 同系物，其平均浓度分别为 318.68μg/kg 和 137.56μg/kg。DOP 和 BBP 的浓度相对较低，并且在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 值和有机质是可能对有机污染物的存在起关键作用的关键环境参数。健康风险评估结果表明，在非饮食条件下，皮肤接触是人体暴露的主要途径，儿童比成年人获得更高的健康风险评分。总的来说，整体健康风险评分处于可接受水平。这些结果为评估保护农业土壤的土壤环境安全性和生态风险提供了参考。
