This study focuses on the health effects of
healthy individuals to ambient levels of tropospheric ozone (O3), a
potent oxidant and outdoor pollutant. More stringent air pollution
legislation has contributed to a downward trend in air pollution levels
over the last two decades. However, approximately 100 million Americans
still reside in areas that exceed the new 8-hour U.S. O3 standard of 80
ppb (3 year average of 4th highest). Primary injury is caused by ozone
is related to ozone's effects on cell membranes and involve lipid
peroxidation. Chronic exposure has been associated with decreased
levels of lung function in children and adolescents. The main study
investigates the effects of long-term exposure to O3 on lung function
in a group of college freshmen. The cohort consists of students who
were lifelong residents of the Los Angeles and San Francisco Bay area.
A sub-cohort of these students participated in an acute-O3 study where
they were exposed to 200 ppb O3 in a chamber.
The goals of this study include: 1) Determining
the effect of short-term and long-term exposure to varying levels of
ambient ozone on cytogenetic damage using the micronucleus (MN) assay,
DNA damage by the COMET assay, 2) Assessing the importance of various
markers of lipid peroxidation (malondialdehyde, 8-isoprostane),
antioxidant status (FRAP) and epithelial injury (CC16), and 3)
Assessing the role of polymorphisms in genes involved in antioxidant
defense (i.e. GST M1, GST P1, SOD, GPX, NQO1).
