根据广西重点环境保护城市南宁、桂林、北海三城市空气质量自动监测数据监测到二氧化硫(SO2),二氧化氮(NO2),可吸入颗粒物(PM10)的日均浓度数据计算的空气污染指数API,结果表明:2002年三城市空气质量状况整体为1级"优"或2级"良",仅南宁市出现过轻度污染共10d,达到了国家环境保护总局对城市环境规定的标准。
The air pollution index API of the three cities of Nanning, Guilin and Beihai, which is the emphasis of environmental protection work, calculated according to the data collected by the automatic detecting system for air quality regarding SO2, NO2 and daily concentration of inhaled particles (PM10) indicated that general air quality in the three cities in 2002 can be classified as ′perfect′ of Grade 1 or ′good′ of Grade 2, meeting the requirement of the State Environmental Protection Ministry on urban environment, except for the slight air pollution lasting for 10 days in Nanning.
