Particulate air pollution is an important environmental health risk. In the present study, we
have investigated the ability of chemically characterized water and organic-soluble extracts
of PM10 from two different regions of Mexico City to induce micronuclei in a human epithelial
cell line. We also evaluated the association between the chemical characteristics of the PM
and its genotoxicity. The airborne particulate samples were collected from an industrial and
a residential region; a Hi-Vol air sampler was used to collect PM10 on glass fiber filters. PM …
