Quality Assurance:A Systematic Approach For A Noimcontinuous Monitoring Network

Abstract

A number of impediments to air quality data base integrity have been evaluated with particular emphasis on noncontinuous high-volume sampler and gas bubbler data. Where sampling stations remote from the laboratory are operated by part-time personnel, special quality control problems arise. Lack of training and motivation of the part-time operators have been shown to be common deficiencies and a method to correct these deficiencies is offered. In addition, potential difficulties such as thermal degradation of the tetrachloromercurate-SO₂ complex in an SO₂ bubbler sample are pointed out as problems which require special precautions to insure sample preservation.
