环境监测现场采样质量影响因素及控制措施

Influencing factors and control measures of sampling quality in environmental monitoring

在环境监测工作中,现场采样质量直接关系后续监测结果的精准度。基于此,本文分析了环境监测现场采样质量控制的目的及问题,从采样准备、设备选择、耗材体系等方面,探析了环境监测现场采样质量影响因素,并从编制现场采样方案、做好现场采样准备、采样仪器设备管理、样品运输质量控制、完善现场采样记录等方面,探究了环境监测现场采样质量控制措施。

In the environmental monitoring work,the quality of on-site sampling is directly related to the accuracy of subsequent monitoring results.Based on this,this paper analyzes the purpose and problems of on-site sampling quality control in environmental monitoring.From the aspects of sampling preparation, equipment selection,consumables system, etc.,it analyzes the influencing factors of sampling quality in environmental monitoring,and prepares on-site sampling plan and performs on-site sampling.In the aspects of preparation,sampling equipment management,sample transportation quality control,and improvement of on-site sampling records,the sampling quality control measures of environmental monitoring sites were explored.
