To understand the remediation potential of peanut plants to phthalate esters (PAEs) contamination, the absorption and accumulation patterns of dibutyl phthalate (DBP), bis (2-ethylhexyl) phthalate (DEHP), and diisononyl ortho-phthalate (DINP), as well as their metabolites-monoalkyl phthalate esters (MPEs), monobutyl phthalate (MBP), monoethylhexyl phthalate (MEHP), and monoisononyl phthalate (MINP), were examined in peanut plant during the entire growth period. It was found that the amounts of DBP and MBP in peanut plants correlated positively, when the DBP content is high, the MBP content is also high, as well as DEHP and MEHP. Additionally, the root contained the highest overall concentrations of DBP, DEHP, DINP, MBP, and MEHP over the course of the growth cycle. To evaluate PAEs contamination and dietary risk of peanuts in China, 18 PAEs and seven MPEs in 490 peanut samples collected from 17 provinces of China were detected by UPLC-MS/MS, the detection rate of 18 selected PAE in peanut was 100%. The dietary risk assessment suggested that the general population and high consuming population are not at risk of non-carcinogenic from the PAEs and MPEs found in peanuts of China. There is no need for the general consumption group to take any precautions against the carcinogenic risk of DEHP, and the high consumption group's carcinogenic risk is also within an acceptable range.
为了解花生植株对邻苯二甲酸酯（PAEs）污染的修复潜力，研究了花生植株在整个生长周期中邻苯二甲酸二丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二异壬酯（DINP）及其代谢产物——单烷基邻苯二甲酸酯（MPEs）、邻苯二甲酸单丁酯（MBP）、邻苯二甲酸单（2-乙基己基）酯（MEHP）和邻苯二甲酸单异壬酯（MINP）的吸收和积累模式。研究发现，花生植株中DBP和MBP的含量呈正相关，DBP含量高时，MBP含量也高，DEHP和MEHP也是如此。此外，在整个生长周期中，根部所含的DBP、DEHP、DINP、MBP和MEHP的总浓度最高。为评估中国花生中PAEs的污染情况和膳食风险，采用超高效液相色谱-串联质谱法（UPLC-MS/MS）检测了从中国17个省份采集的490份花生样品中的18种PAEs和7种MPEs，所选取的18种PAE在花生中的检出率为100%。膳食风险评估表明，中国花生中发现的PAEs和MPEs对一般人群和高消费人群不存在非致癌风险。一般消费群体无需对DEHP的致癌风险采取任何预防措施，高消费群体的致癌风险也在可接受范围内。
