| 摘 要： | 利用高效液相色谱测定了北京和广州地区大气过氧化物浓度，并分析了相关因素对过氧化物浓度变化的影响。北京地区在5月、6月和9月3个监测时段中H2O2的平均浓度分别为2.33×10-9、0.338×10-9和0.148×10-9；广州11月H2O2的平均浓度为0.168×10-9(VH2O2/Vair)。植物排放对有机过氧化物的生成有一定贡献，有机过氧化物浓度变化与H2O2浓度变化具有较好的一致性。过氧化物浓度与O3和甲醛浓度表现出较好的正相关性，而与SO2浓度则表现出负相关性。

| Abstract: | The concentration of peroxides in atmosphere in Beijing and Guangzhou was measured by using the HPLC post-column derivatization system. The H2O2average concentration was 2.33×10-9, 0.338×10-9 and 0.148×10-9(VH2O2Vair) respectively in May, June and September, 2000 in Beijing. The H2O2 average concentration was 0.168×10-9VH2O2/Vair) in November, 2000, in Guangzhou. The factors that affected peroxides were discussed. The results showed that peroxide concentration was high in daytime and low at night in both sites. Variation of concentration of organic peroxide is similar to that of hydrogen peroxide. The concentration of peroxides has positive correlation with that of O3 and HCHO. |
