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

Is Drinking Water a Significant Source of Human Exposure to Chemical Carcinogens and Mutagens?y were made by Heuper and Ruchhoft (1954), who tested carbon-chloroform extracts from the following samples: a gravity oil separator effluent from a petroleum refinery; raw water from a canal polluted by wastes from a petroleum refinery; raw water from Nitro, WV (the Kanawha River); and finished wat

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. The organic matter in drinking water and wastewater is a comp

Short-Term Methods for Assessing , Carcinogenic Activity of Complex Mixturescision scheme (Bridges, 1973; Weisburger and Williams, 1977; Bull and Pereira, in press). In tier 1, the samples are screened for evidence of carcinogenic and mutagenic activity. The Ames . mutation bioassay and . and . cytogenetic assays appear to sucessfully identify most chemicals and samples wit
