Genetic Toxicology of Airborne Particulate Matter Using Cytogenetic Assays and Microbial MutagenicitSCEs), chromosomal aberrations (CAs), and the micronucleus (MN) test in human lymphocytes. Two types of extracts were used for all the tests. The first was a sample obtained from urban air in winter which showed high mutagenic activity. The second was a summer sample, again from urban air, which sho

Indoor and Outdoor Sources of Airborne Mutagens in Nonurban Areas, particulate matter may have other toxicological implications than gaseous pollutants, which all may penetrate the lower part of the respiratory tract. In addition, suspended particulate matter represents a group of pollutants of variable physical as well as chemical composition. Therefore, airborn

These studies seem partly due to a hypothesis that the urban air pollution was a major factor causing the increased lung cancer incidence observed at that time, although data were emerging showing that lung cancer is due largely to tobac

Assessment of the Mutagenicity of Volatile Organic Air Pollutants Before and After Atmospheric Transund in the urban atmosphere (20). The majority of these studies examined the organic material associated with particles emitted from specific sources (11). In contrast, only a few studies have examined volatile airborne organic compounds before and after they undergo atmospheric transformation (13).

Experimental and Epidemiologic Applications to Cancer Risk Assessment of Complex Mixtures complex mixtures, and thus to give a more precise and reliable risk assessment, there is a need for extensive experimental research as well as development of the risk assessment strategies. In the international workshop held in Espoo, Finland, in May 1989, the lines of exploration that are likely t
