Abstract：
The research aims to evaluate the source, dispersion, and human health risk assessment of PAH-contaminated Talinum Triangulare grown along the polluted Ikpoba River. The freeze-dried vegetables were sonicated with dichloromethane for an hour and then concentrated using a rotary evaporator. The extract was purified using a glass column with anhydrous Na2SO4 and silica gel and analyzed using gas chromatography-mass spectrometry (GC-MS). The distribution of the contaminants showed that Pyrene < Benzo(a)anthracene ≤ Fluorene < Phenathrene ≤ Naphthalene ≤ Acenaphthene < Anthracene ≤ Acenaphthylene, while Pyrene < Benzo(a)anthracene < Fluorene < Phenathrene < Acenaphthalene ≤ Naphthalene < Anthracene < Acenaphthylene in wet and dry periods, respectively. The average ∑8 PAHs was 0.85 mg/kg and 0.75 mg/kg in wet and dry periods, respectively, and showed a decrease of 17.64% from wet to dry periods. The daily average dose revealed that the infant male and the adult female consumed the least and highest doses of T. Triangulare (TT), respectively. Furthermore, the hazard quotient and hazard index were < 1 for all the target groups, with adult females having higher values in both seasons. However, the incremental life cancer risk of the target group was between potential and high-potential cancer risk, with adolescent males and adult females more prone to low and high cancer risk, respectively. The isomer ratio and multivariate statistics revealed the sources of the PAH-contaminated TT to be more from pyrolysis.
摘要：
该研究旨在评估来源，色散，在污染的Ikpoba河沿岸生长的PAH污染的TalinumTriangular和人类健康风险评估。冷冻干燥的蔬菜用二氯甲烷超声处理1小时,然后使用旋转蒸发器浓缩。使用具有无水Na2SO4和硅胶的玻璃柱纯化提取物,并使用气相色谱-质谱(GC-MS)分析。污染物的分布表明，芘<苯并（a）蒽≤芴<菲≤萘<蒽≤乙炔，而在干湿时期,芘<苯并(a)蒽<芴<菲<萘<蒽<乙炔,分别。干湿期∑8PAHs平均为0.85mg/kg和0.75mg/kg,分别,从潮湿到干燥，减少了17.64％。每日平均剂量显示，婴儿男性和成年女性消耗最少和最高剂量的三角弧菌（TT），分别。此外，所有目标群体的风险商和风险指数均<1，成年女性在两个季节都有更高的价值。然而,目标人群的生活癌症风险增量介于潜在和高潜在癌症风险之间，青少年男性和成年女性更容易患癌症的风险低和高，分别。异构体比率和多变量统计数据表明，受PAH污染的TT的来源更多来自热解。
