研究了珠江三角洲水源地水体溶解相（DP）、悬浮颗粒物（SPM）和沉积物中16种优先多环芳烃（PAHs）的含量。16种多环芳烃的浓度总和在DP水中为92.8 ~ 324 ng/L，在SPM中为28.8 ~ 205 ng/L，在沉积物中为55.7 ~ 381 ng/g （d.w）。与全球其他地区相比，DP和SPM中的PAH水平相当中等，沉积物中的PAH水平相对较低。多环芳烃的空间分布具有站点特异性，在人口密集和交通繁忙的地区，多环芳烃含量相对较高。多环芳烃以二环和三环多环芳烃为主，多环芳烃污染主要来源于热解过程。基于风险商，水的生态风险被评为中等，但与水摄入相关的不良健康风险最小。沉积物样品中的萘和芴在某些地点显示出潜在的生物损伤；然而，平均效应范围中位数商表明，多种多环芳烃的生态风险很低（不良反应发生率低于10%）。
Sixteen priority polycyclic aromatic hydrocarbons (PAHs) were investigated in the water dissolved phase (DP), suspended particulate matter (SPM), and sediment collected from the water source zone of the Pearl River Delta region. The sum of 16 PAH concentrations ranged from 92.8 to 324 ng/L in the water DP, from 28.8 to 205 ng/L in the SPM, and from 55.7 to 381 ng/g (d.w.) in the sediment. Compared with other areas globally, the PAH levels were considerably moderate in the DP and SPM and relatively low in the sediment. Spatial distribution of PAHs was site-specific, and relatively higher PAH levels were found in the areas with dense population and heavy traffic. The PAH profile was dominated by two- and three-ring PAHs, and PAH pollution was identified of pyrolytic origins. Based on risk quotient, the ecological risk in water was ranked as moderate, but the adverse health risk associated with water ingestion was minimal. Naphthalene and fluorene of the sediment samples showed potential biological impairment in some locations; nevertheless, the mean effects range median quotient suggested that the ecological risk of multiple PAHs was quite low (less than 10% incidence of adverse effects).
