Abstract

The status, health risk and sources of street-dust-borne polycyclic aromatic hydrocarbons (PAHs) were investigated in Marvdasht city. The total concentration of 15 PAHs ranged from 932.85 to 5030 μg kg-1 with a mean of 2185.7 μg kg-1. The PAHs contained 2-6 rings and the level of five carcinogenic PAHs generally accounted for 5-40% of total concentration. The statistical analysis and diagnostic ratios demonstrated that the main emission source of PAHs is traffic. The toxic equivalent concentrations (TEQs) of PAHs in street dust ranged from 12.91 to 1160.88 μg kg-1, with a mean of 257.18 μg kg-1. High correlation coefficients (r > 0.9, p < 0.01) between benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[g,h,i]perylene, indene and toxicity equivalent concentrations of street dust indicated that these PAHs are predominant contributors to TEQ. The results of total incremental lifetime cancer risk (ILCR) demonstrated that Marvdasht's residents are potentially exposed to high cancer risk via dust ingestion and dermal contact.

伊朗西南部马尔夫达什特市街道灰尘中的多环芳烃：浓度、健康风险评估和来源分析

对马尔夫达什特市街道扬尘多环芳烃（PAHs）的现状、健康风险和来源进行了调查。15种PAHs的总浓度范围为932.85至5030μ。PAHs含有2-6个环，五种致癌PAHs的含量通常占总浓度的5-40%。统计分析和诊断率表明，多环芳烃的主要排放源是交通。街道灰尘中PAHs的毒性当量浓度（TEQ）为12.91至1160.88μg kg-1，平均值为257.18μg kg-1。苯并[a]芘、二苯并[a，h]蒽、苯并[g，h，i]苝、茚和街道灰尘的毒性当量浓度之间的高相关系数（r>0.9，p<0.01）表明，这些多环芳烃是TEQ的主要贡献者。癌症总增加寿命风险（ILCR）的结果表明，Marvdasht的居民可能通过摄入灰尘和皮肤接触而暴露于癌症高风险中。
