Abstract:

Accurate and reliable environmental monitoring data is an important practical basis for environmental management, therefore, the correct identification and processing of abnormal data is a key link in environmental monitoring. The types and causes of abnormal environmental monitoring data are briefly described, and the processing methods of abnormal monitoring data are analyzed. It is proposed that a sound quality management system for environmental monitoring should be established, attention should be paid to the information management of on site sampling, the original monitoring records should be filled correctly, and the monitoring data audits should be strengthened.
