摘要
文章根据宜宾市2001～2005年大气降水监测数据资料,对酸雨污染状况及变化趋势进行分析。结果表明,宜宾市酸雨频率高、酸度强,酸雨污染呈逐年加重趋势。降水组份中,SO42-/NO3-比值逐年上升,说明煤烟型大气污染未得到根本转变。
The routine monitoring data of acid rain in Yibin City are collected covering the period from January 2001 to December 2005. Seasonal variation is analyzed and future trend is predicted based on the detailed information of chemical constituent of the rainwater,e.g. SO42-,NO3-. It is concluded that main source of the acid is from local coal burning industries.
