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 of environmental monitoring site

环境监测工作中,往往技术人员都会把重心放在实验室分析,而忽视室外的现场采样工作,其实现场采样也是环境监测工作中的重点内容,会对监测结果造成直接影响。一般来说现场采样会受到较多的非人为因素的影响,涉及范围大、环境复杂、综合性较强,在实际操作过程中难以控制。因此,要对环境监测现场采样工作质量影响因素进行分析,采取有效的控制措施保证现场采样的质量。

In environmental monitoring,technicians often focus on laboratory analysis and ignore outdoor field sampling.In fact,field sampling is also a key content in environmental monitoring,which will directly affect the monitoring results.Generally speaking,on-site sampling will be affected by more non-human factors,involving a large range,complex environment,and strong comprehensiveness,which is difficult to control in the actual operation process.Therefore,it is necessary to analyze the factors influencing the quality of on-site sampling in environmental monitoring and take effective control measures to ensure the quality of on-site sampling.
