The manual describes sampling approaches for conducting Level I, II, and III environmental source assessment surveys of the feed, product, and waste streams associated with the production of organic materials. Level I provides large quantities of sample in a short time period for both analysis of the chemical classes of compounds present and biological testing programs. Level II is a more detailed qualitative and quantitative chemical analysis of the organic components. Level III is a quantitative study of the effect of process variables on the emission rates of specific organic materials. The manual: provides specific methods to be used in Level I to obtain samples from stationary sources, fugitive emission sources, and process and waste streams (including gas, liquid, and solid phases); and provides the current state-of-the-art, an extension of the state-of-the-art sampling methods that are available for application to Level II and III studies. The manual is directed to those who are basically experienced in sampling techniques and will be required to apply these methods in source assessment programs.
