总悬浮颗粒物不同采样方法的比较分析

摘要

环境保护部新颁布的环境空气质量标准GB 3095－2012中，总悬浮颗粒物（ TSP ）的采用时间有原先的日均采用12h变为24h，而标准限值没有变化。按照旧标准GB 3095－1996的TSP采集12h样品，在不同的监测点位，一天分成了四个不同的时间段进行采集，然后不同采样方法的浓度值进行比较分析。%In the new ambient air quality standard GB 3095-2012 issued by the Ministry of Environmental Protection of the PRC, the daily data-collection time of the total suspended particles ( TSP ) has been changed from 12h to 24h, with the maximum standard unchanged. In accordance with the former standard GB 3095-1996, we collected TSP samples in different methods at different monitoring sites in four specified periods within 12h.
