Concentration, source, and risk of PAHs were investigated in 31 sites from surface soils of Liaohe estuarine wetland. Total PAHs concentrations ranged from 293.4 to 1735.9 ng/g with a mean of 675.4 ng/g. The 3- and 4-ring PAHs were the dominant species. The ratios of high-molecular weight PAHs to low-molecular weight PAHs and anthracene/(anthracene+phenanthrene) were calculated to apportion sources of PAHs. It was found that both pyrogenic and petrogenic PAHs sources were important. Effect range low and effect range median showed that the PAHs would occasionally cause adverse effects. The nemerow composite index revealed that about 41.9% soil sampling sites were safety; about 58.1% sites had different grades of PAHs pollution.
在辽河河口湿地的 31 个采样点调查了多环芳烃（PAHs）的浓度、来源及其风险。多环芳烃的总浓度范围为 293.4 至 1735.9ng/g，平均值为 675.4ng/g。3 环和 4 环多环芳烃是主要成分。高分子量多环芳烃与低分子量多环芳烃的比值以及蒽/（蒽+菲）的比值被用来分配多环芳烃的来源。结果表明，无论是热成因还是母岩成因的多环芳烃来源都很重要。效应区间低值和效应区间中值表明，多环芳烃偶尔会造成不良影响。内梅罗综合指数表明，约 41.9%的土壤采样点是安全的；约 58.1%的采样点存在不同程度的多环芳烃污染。
