The measurement was made in 3 periods from May to September of 2000 in Beijing. The measurement species included SO4(2-), NO3-, NO2-, Cl- of aerosol and related gases. The hourly variation of the concentration was presented. It showed that NO3-, NO2-, Cl- of aerosol and HCl, HNO2, HNO3 of gas varied with regularity. The variation of gas SO2 and aerosol SO4(2-) depended on the emission of SO2. The peak time of SO4(2-) was about 2 hours later than SO2.
该测量于2000年5月至9月在北京分三个阶段进行。测量的物种包括气溶胶及相关气体中的硫酸根离子(SO4(2-))、硝酸根离子(NO3-)、亚硝酸根离子(NO2-)、氯离子(Cl-)。给出了浓度的每小时变化情况。结果表明,气溶胶中的硝酸根离子(NO3-)、亚硝酸根离子(NO2-)、氯离子(Cl-)以及气体中的氯化氢(HCl)、亚硝酸(HNO2)、硝酸(HNO3)呈规律性变化。气体二氧化硫(SO2)和气溶胶硫酸根离子(SO4(2-))的变化取决于二氧化硫的排放。硫酸根离子(SO4(2-))的峰值时间比二氧化硫约晚2小时。
