Risk Management for Monitoring Data Quality of Macroinvertebrate in Freshwater
Risk events affecting monitoring data quality of macroinvertebrate in freshwater were identified by risk management from both quality management system and monitoring process.By consulting experts,the proba-bility and severity of risk events were rated,a risk matrix was established for comprehensive risk evaluation,and prevention and control countermeasures were formulated.The results indicated that a total of 24 risk events were identified.5 high-risk events were mainly related to professional skills,18 medium risk events were mainly related to the implementation of standard specifications and work experience,and one low-risk event was related to laboratory standardization.From the perspective of risk distribution,high and medium risk events oc-curred most frequently during sampling collection process,followed by sample identification process.In this re-gard,it was proposed to focus on enhancing professional skills of monitoring personnel,comprehensively improve the quality management system,strictly carry out sample collection and sample identification quality control,and continuously improve risk management to form a virtuous cycle of identification and prevention.
