上海市浦东新区PM2.5污染水平及其主要成分的分布特征

Pollution Level and Major Constituents Distribution Characteristics of PM2.5 in Pudong New Area, Shanghai

  • 摘要: 目的

    了解上海市浦东新区PM2.5 污染水平及其主要成分的分布特征。

    方法

    在上海市浦东新区设置5 个监测点,于2014 年9 月-2015 年8 月共采集有效PM2.5 样品409 件,并对其中15 种多环芳烃和21 种重金属进行含量分析。

    结果

    研究期间PM2.5 日平均质量浓度80.98 μg/m3,超标率44.3%,最高超标倍数3.5 倍;15 种优控多环芳烃在PM2.5 中均有检出,总体平均质量浓度为(9.694±10.012)ng/m3,含量最高为苯并gh,i芘(1.836 ng/m3),最低为蒽(0.046 ng/m3);21 种重金属总平均浓度为1 540.397 ng/m3,含量最高为铁(671.0 ng/m3),含量最低为铍(0.035 ng/m3);PM2.5 污染水平及其多环芳烃和重金属成分均存在季节差异(P<0.01),即冬春季高于夏秋季,各监测点之间总体上差异无统计学意义(P >0.05)。

    结论

    上海市浦东新区PM2.5 污染水平较高,PM2.5 质量浓度及其多环芳烃和重金属成分均存在明显的季节差异,不同监测点之间未见差异。

     

    Abstract: Objective

    To understand the pollution level of PM2.5 and characteristics of its major constituents in Pudong New Area, Shanghai.

    Method

    PM2.5 samples (n=409) of five monitoring sites in Pudong New Area of Shanghai were collected between September 2014 and August 2015. The mass concentrations of PM2.5, 15 polycyclic aromatic hydrocarbons (PAHs), and 21 heavy metals were measured.

    Result

    The daily average mass concentration of PM2.5 was 80.98 μg/m3, and 44.3% samples exceeded relevant limits, with a maximum excess multiple of 3.5. The selected 15 PAHs were detected in all PM2.5 samples, and the average mass concentration of Σ15PAHs was (9.694±10.012)ng/m3; specifically, the highest PAH concentration was found for benzog, h, ipyrene (1.836 ng/m3), whereas the lowest was for anthracene (0.046 ng/m3). The average mass concentration of 21 heavy metals was 1 540.397 ng/m3, the highest concentration was found for iron (671.0 ng/m3), and the lowest was for beryllium (0.035 ng/m3). PM2.5 and its constituents showed significant seasonal variations (P<0.01), namely winter-spring higher than summer-autumn, but non-significant results between different monitoring sites (P >0.05).

    Conclusion

    A high PM2.5 pollution level is identified in Pudong New Area of Shanghai. PM2.5, PAHs, and heavy metals show seasonal variations, but no spatial variation.
