Mutagenic activity of total and particle-sized fractions of urban particulate matter
Article Abstract:
The PM10 atmospheric particulate matter from Bologna, Italy was analyzed to determine its mutagenic activity. The mutagenic activity of the urban particulate matter is dependent on the region and meteorological conditions of the sampling site. Seasonal variations also affect the mutagenic activity of particle-sized urban PM10 which exhibited high levels during cold seasons due to the use of water heaters. However, the total levels of particulate matter did not correlate with mutagenic activity.

Chemical characterization of mutagenic fractions of particles from indoor coal combustion: a study of lung cancer in Xuan Wei, China
Article Abstract:
The lung cancer mortality rate for females in China is particularly high in Xuan Wei County. The use of smoky coal in unvented areas has been found to increase the risk of lung cancer. The bioassay-directed fractionation technique was used to identify the chemical components that may cause lung cancer. The results suggested that the high rate of lung cancer in Xuan Wei may be the result of the presence of three to four-ring alkylated polycyclic aromatic hydrocarbons.

Exposure to carcinogenic PAHs in the environment
Article Abstract:
Eight polynuclear aromatic hydrocarbons (PAHs) may be carcinogens. Volcanic eruptions and forest fires can release PAHs, but fossil-fuel combustion sources, such as automobiles, have raised the level of PAHs in the environment dramatically. PAHs can be present in food, water, air, soil and sediments. Research indicates that the primary source of carcinogenic PAHs for nonsmokers may be food and that air can be a major source of carcinogenic PAHs in urban areas.
