对污染源排气中颗粒物监测规范的补充建议

A Supplement to the Monitor Specification of Particulates Emitted from Exhaust Gas of Stationary Source

在我国的环境监测技术规范中，对固定污染源排气中颗粒物浓度的测定要求采三个以上平行样，但未对平行样的精密度作出相应的要求．讨论了固定污染源排气中颗粒物浓度的测定综合误差，从理论上推出较适合我国目前使用的监测平行样允许偏差范围值，并通过实际监测数据对其合理性给予了论证．

In the environment monitor technique standard of our country,there must be at least three duplicate samples in the determination of particulate concentration emitted from exhaust gas of stationary source,but there are not corresponding demands on the precision of duplicate samples.In this article,we discussed the determination comprehensive error,gathered the tolerance bias range value of monitoring duplicate samples theoretically which can be used now in our country,and proved the accuracy by actual monitoring data.
