Evaluation of Collection and Extraction Methods for Mutagenesis Studies on Ambient Air Particulatea short-term microbial bioassay (Lewtas Huisingh, 1980; Teranishi et al., 1977). The identification and characterization of the potentially hazardous chemical components associated with ambient air particles requires that efficient collection and extraction methods be developed and validated. It is

Alternative Strategies and Methods for Concentrating Chemicals from Waterrial or sewage effluents. Generally, the biologically active materials will be present in concentrations too low to be detected by testing the small amount of aqueous sample that can be incorporated directly into a biological test system.
