摘　　要：以重量法为原理的手工监测法是国内外监测环境空气PM2.5质量浓度的标准方法,在空气质量监测中具有重要应用。该文以2012年跨4个季度近150 d的PM2.5手工监测实际操作经验为基础,重点探讨了手工监测法各环节的监测技术要点,如手工监测采样器的操作技术、滤膜种类的选择及前处理要求、滤膜更换技术、滤膜平衡和称重条件、质量保证和质量控制技术等,以期为推广PM2.5手工监测法提供技术参考。Manual monitoring （ gravimetric method） is the standard method of PM2.5 mass concentration measurement in ambient air at home and abroad, with important applications in air quality monitoring. Based on the practical experiences from PM2.5 manual monitoring for nearly 150 days in four seasons of 2012, this study emphasized on the discussions about the key points of monitoring techniques of PM2.5 manual monitoring method, such as the operating techniques of PM2.5 manual monitoring samplers, the choice of filter types and pretreatment requirements, the environmental conditions for filters balancing and weighing, QA/QC and so on. The purpose of this study is to provide technical support and reference for the promotion of PM2.5 manual monitoring method.
