title: Application of industrial hygiene air sampling data to the evaluation of controls for air contaminants.
abstract: Air contaminant concentration measurements are an important part of the evaluation of a local exhaust system's effectiveness. Comparisons of concentration measurements have been used to assess the importance of work practices and emission sources in relation to the worker's exposure. These comparisons can be stated as a null hypothesis. Statistical tests can be used to evaluate the validity of the null hypothesis. Applicable tests include student t-test, analysis of variance and Duncan's Multiple Range Test.
