Abstract: The high-time-resolution atmospheric mixing ratio data were sampled at Peking University. The data was analyzed and led to the conclusion that HCFC-22 was the proper reference substance; CO, the idiomatic reference, was not suitable for interspecies correlation analysis when dealing with data from urban districts. Based on the observation data of HCFC-142b and HCFC-22 gained from four representative cities (Beijing, Hangzhou, Lanzhou and Guangzhou) in four seasons, China’s HCFC-142b emission in 2012 was calculated by interspecies correlation. The result was 16.24 (13.90?18.58) kt, equivalent to 1.06 kt ODP and 37 Tg CO2-eq, taking up 9.78% (ODP) of total HCFCs emission in China or 30.5% of global HCFC-142b emission. Therefore, China’s HCFC-142b control would play an important role in phasing out HCFCs domestically and globally.

摘要: 利用北京大学定点较高时间频率浓度监测数据, 甄选HCFC-22为估算HCFC-142b排放量适宜的参考物质, 分析认为以往基于背景地区数据的研究中普遍采用的参考物质CO不适用于利用城市地区大气样品进行物种间浓度相关法研究。根据全国四城市(北京、杭州、兰州和广州)四季的HCFC-142b及其参考物质浓度监测数据, 通过物种间浓度相关法计算2012年中国HCFC-142b排放量为16.24 (13.90~18.58) kt, 相当于1.06 ODP kt和37 Tg CO2-eq, 占2012年中国HCFCs 排放总量的9.78% (ODP), 占全球HCFC-142b排放总量的30.57%。中国HCFC-142b的减排淘汰工作将在未来中国和全球成功履约中占据重要地位。
