摘要:
为独立评估环境空气连续自动监测系统运维质量,掌握环境空气监测数据准确性等信息,我国开展了环境空气连续自动监测系统性能审核工作,通过分析影响审核结果的相关因素,提出,性能审核标准气体浓度应接近实际监测空气中的气体浓度,性能审核时间的选择应满足《环境空气质量标准》(GB 3095—2012)中数据统计的有效性规定,性能审核气体压力应保持恒定并接近实际采样时的气压,标准气体进样方式应通过日常采样管路等,从而进一步提高性能审核结果的科学性和准确性,为生态环境管理部门了解环境空气数据质量提供坚实基础。

Discussion on Performance Audit of Continuous Automatic Monitoring System for Ambient Air

Abstract:
In order to independently evaluate the operation and maintenance quality of automatic monitoring system for ambient air and to master the accuracy of the monitoring data and other information, China has carried out the performance auditing of the continuous automatic monitoring system for ambient air. By analyzing the relevant factors affecting the audit results,the performance auditing gas concentration should be close to actual monitoring of air concentration, it is proposed that the selection of performance audit time should meet the validity requirements of data statistics in ambient air quality standards (GB 3095—2012), the performance audit gas pressure should be kept constant and close to the actual sampling pressure, and the audit gas sampling method should be through routine sampling pipelines, etc.,thus to further improve the scientific and accuracy of performance auditing results. It provides a solid foundation for the ecological and environmental management departments to master the quality of ambient air data.
