The purpose of this study is to evaluate existing manual methods for analyzing asbestos, beryllium, lead, cadmium, selenium, and mercury and from this evaluation to provide the best and most practical set of analytical methods for measuring emissions of these elements from stationary sources. The work performed in this study was divided into two phases Phase I was limited to surveying sources of information and summarizing the findings in terms of existing methods; totally new methods were not developed. However, in the case of asbestos and mercury it was necessary to modify existing methods significantly, and some laboratory and field testing was performed during Phase I to develop these two methods. Phase II was concerned with the testing, evaluation, and modification of the methods of analysis developed during Phase I. Both laboratory and field tests were conducted during this phase of the work.
