摘　　要：目的了解上海市浦东新区道路交通环境PM_(2.5)污染状况及特征,为控制交通污染提供依据。方法在上海市浦东新区环境空气质量监测国家控制点附近设置3个监测点(A、B和C点),于2016年9月、12月和2017年3月、6月每月分别开展为期为1周的PM_(2.5)样品采集,并对其中21种重金属和15种多环芳烃进行成分分析,收集采样期间国控点连续监测报道的PM_(2.5)日平均数据。结果 A、B和C点PM_(2.5)年平均浓度分别为94.51、130.01和98.74μg/m^3,明显高于国控点监测结果,差异有统计学意义(均P<0.05);21种金属成分中前10位为Fe^(56)、Al^(27)、Zn^(66)、Mn^(55)、Ba^(137)、Cu^(63)、Pb^(208)、Cr^(52)、Sr^(88)、V^(51);3个监测点PM_(2.5)中15种多环芳烃[ρ(∑PANs)]平均值分别为4.43、4.51、4.92 ng/m^3,差异无统计学意义(P>0.05),组成中前5位为苯并[g,h,i]芘、茚并[1,2,3-cd]芘、苯并[b]荧蒽、苯并[a]芘、芘。结论上海市浦东新区道路交通环境PM_(2.5)污染水平明显高于国控点,PM_(2.5)中锌、锰、铜、铅等重金属和苯并[g,h,i]芘、茚并[1,2,3-cd]芘、苯并[b]荧蒽、苯并[a]芘等多环芳烃相对含量较高。[Objective]To investigate the PM2.5 pollution status and characteristics of in road traffic environment in Pudong New Area of Shanghai, provide basis for controlling traffic pollution. [Methods] Three monitoring points（A point, B point and C point） were set up near the National Air Quality Control Point in Pudong New Area of Shanghai. A one-week PM2.5 sample collection was conducted in September and December 2016 and March and June 2017 respectively and the compositions of 21 heavy metals and 15 polycyclic aromatic hydrocarbons PANs in the sample were analyzed. Daily average data of PM2.5 reported by the continuous monitoring of urban state control points during the sampling period were collected. [Results] Annual average concentration of PM2.5 at A point, B point and C point was 94.51 μg/m^3, 130.01 μg/m^3, and 98.74 μg/m^3, respectively, and all of them were significantly higher than the monitoring results of their corresponding environmental monitoring stations（P〈0.05）.The top ten of 21 metal components were Fe^（56）, Al^（27）, Zn^（66）, Mn^（55）, Ba^（137）, Cu^（63）, Pb^（208）, Cr^（52）, Sr^（88）, V^（51）. At the three monitoring roads, PM2.5 contained 15 types of PAHs[ρ（∑PANs）] with mean values of 4.43 ng/m^3, 4.51 ng/m^3 and 4.92 ng/m^3. The difference was not statistically significant（P〉0.05）. The top five positions were benzo [g,h,i] anthracene, anthraxo[1,2,3-cd]anthracene,benzo[b] fluoranthene, benzo[a] anthracene, and pyrene.[Conclusion] The PM2.5 pollution level at the intersection of Pudong New Area is significantly higher than that of the environmental monitoring station, and the higher contents of PM2.5 is zinc,manganese, copper, lead in heavy metals and benzo[g,h,i] indene, indeno[1,2,3-cd] anthracene, benzo[b] fluoranthene, benzo[a] pyrene in PAHs.
