| 中文摘要 |
| 借鉴美国EPA关于PM2.5连续监测仪器手工采样比对测试的性能指标和检测方法,结合我国现行的相关技术规范,选取两种不同原理4种型号典型的进口和国产环境空气PM2.5连续自动监测系统,分别在春、夏、秋、冬这4个季节开展了PM2.5连续自动监测与手工采样测量(重量法)之间的比对测试. 研究确定了符合我国环境质量现状和环境监测管理需求的PM2.5连续监测系统与手工采样比对测试(调试)的质控措施要求(手工采样测量结果平行性≤ 5μg ·m-3或5%)和技术指标要求(线性回归方程斜率1±0.15; 截距0±10; 相关系数≥0.95)以及相应的操作方法,为我国环境空气PM2.5连续自动监测系统的现场有效使用和数据质量保证提供了必要的技术手段和质控方法. |

| According to the U.S. EPA performance index and detection methods for comparison test of PM2.5 continuous monitoring system, in combination of the current related technical specifications in China, 4 types of typical imported and domestic PM2.5 continuous monitoring system with two different principles were tested and compared to the manual sampling measurement (gravimetric method) in spring, summer, autumn and winter. This research determined the quality control requirements (parallelism of manual sampling measurement results ≤5μg ·m-3 or 5%), the technical index (slope of linearity regression equation 1±0.15; intercept 0±10; correlation coefficient ≥0.95), and corresponding detection methods of reference method comparison test to PM2.5 continuous monitoring system, which meets the requirement of current environmental quality status and environmental monitoring and management in China. It also provided technical means and method of quality control for effective use and data quality of PM2.5 continuous monitoring system in China. |
