上海某大型化工区周边大气细颗粒物中多环芳烃的分布特征

Distribution Characteristics of Polycyclic Aromatic Hydrocarbons in Fine Particulate Matters in Proximity of a Large Chemical Industrial Park in Shanghai

  • 摘要: 目的 了解上海某大型化工区大气细颗粒物(PM2.5)中多环芳烃水平。

    方法 在该化工区下风向3 km内的监测点A和下风向30km的监测点B (对照)分别设置采样点,于2014年6月3-5日连续采样3次,测定PM2.5及PM2.5中16种多环芳烃浓度。

    结果 化工区周边大气多环芳烃总质量浓度(13.64& #177;2.25)ng/m3,高于对照区(6.00& #177;1.59)ng/m3,差异有统计学意义(P<0.05);化工区周边大气PM2.5浓度为(70.84& #177;15.35)μg/m3,对照区为(85.74& #177;12.73)μg/m3,差异无统计学意义(P>0.05);化工区周边单位质量PM2.5携带的多环芳烃(201.19 mg/g)约为对照区的(74.64 mg/g)2.7倍,差异有统计学意义(P<0.05)。

    结论 上海某大型化工区周边大气多环芳烃浓度较对照区稍高。

     

    Abstract: Objective To measure the concentrations of polycyclic aromatic hydrocarbons (PAHs) in fine particulate matters (PM2.5) in proximity of a large chemical industrial park in Shanghai.

    Methods The concentrations of PM2.5 and 16 PAHs in PM2.5 were determined in area A (in 3km proximity downwind of the chemical industrial park) and area B (control, 30km away from the chemical industrial park) after consecutive three days of sampling in 3-5 June 2014.

    Results The concentration of total PAHs in area A was (13.64& #177;2.25) ng/m3, significantly higher than that in area B of (6.00& #177;1.59) ng/m3 (P<0.05). The concentrations of PM2.5 in area A and area B were (70.84& #177;15.35) μg/m3 and (85.74& #177;12.73) μg/m3 respectively (P>0.05). The weight of PAHs per gram of PM2.5 in area A (201.19 mg/g) was about 2.7 times that in area B (74.64 mg/g) (P<0.05).

    Conclusion The levels of PAHs close to the large chemical industrial park in Shanghai are higher than those away from this place.
