中文摘要: 大气污染物对独山子区环境空气质量的影响从潜在的威胁上升到突出的环境问题。挥发性有机物(VOCs)和二次污染物又是石油化工地区大气环境中比较突出的毒害物质。本研究拟通过在独山子生活区、工业区系统的长期野外观测,一方面利用PM2.5大流量采样器采集样品,用SOA-tracer的方法分析、估算二次有机气溶胶(SOA);另一方面采集、分析VOCs样品,利用PMF受体模型方法对VOCs来源进行定性定量解析,探讨VOCs的日变化、季节变化、源变化特征;大气VOCs中的苯系物是有效控制空气中二次污染物的关键途径。本研究拟收集当地环境监测部门的O3、NOx数据,探讨苯系物、C2-C4烯烃和NOx对O3的贡献率,分析出该地区O3的主要来源;采用SPSS软件对SOA和VOCs中苯系物的各组分进行多元回归,确定各组分对SOA的贡献率,为科学的控制该石化地区污染源的决策提供理科学的论依据。

英文摘要: Atmospheric pollutants is the most prodominent threats to the environmental air quality of Dushanzi district.Volatile organic compounds (VOCs) and secondary pollutants is the prominent hazardous pollutants in the atmospheric environment of the petrochemical area. In this study long-term observations and samlping will condut different area, namly living area and industrial area of Dushanzi district. On the one hand, PM2.5 sample will be collect using by high-valume samlper and secondary organic aerosol measured with the means of SOA-tracer mathod. On the another hand, PMF mathod will be use to identify the sources of atmospheric VOCs and daily and seasonal variation VOCs. The BTEX is the key to effective control of secondary air pollutant. In this study O3 and NOx data will be collect from local environmental monitoring department to investigate the source apportionment of BTEX, C2-C4 olefins and NOx on O3. Multiple regression will be conduct by using SPSS software to investigate the contrubution of BTEX toVOCs and this will be provide sicentific basis for the control of pollution in the petrochemical industral district.
