摘要
作者对我国贵阳、重庆、成都等酸雨地区的大气环境及降雨中的有机成份和酸性物质进行了系统监测,研究了各种有机物质在促进SO_2向SO_3转化,进而生成硫酸以及各种碳氢化合物,在大气环境中经光化学反应生成有机酸中的作用。用计算机模拟贵阳地区大气化学反应过程,进行了模式计算和现场各种酸的实际测定,对主要酸性物质H_2SO_4,HNO_3及有机酸对酸雨的相对贡献率进行了估算。
Organic and acidic substances in the atmospheric environment and rain were continuously and systematically monitored in Southwest China(Guiyang, Chongqing and Chengdu)for four years (1986-1989) . The role of various organic substances in promoting SO2 transformation into SO3 and then to form H2SO4, and the effect of hydrocarbon on the formation of organic acids by photochemical reaction in the atmosphere are described. The atmospheric chemical reaction processes were simulated the model verified with data of field measurement. The relative contribution of major acidic substances (H2SO4, HNO3 and organic acid) to acid rain was evaluated.
