Exposure to air pollutants and the incidence of lung cancer

Research suggests that exposure to air pollution contributes to small increases in lung cancer rates. However, errors in measurement of air pollution exposure, as well as in measurement of other risk factors such as cigarette smoking, limit the ability to quantify the extent to which air pollution increases risk of lung cancer. Elizabeth Matovinovic is developing an assessment of air pollution exposure for British Columbia, which will include an estimate of individual exposures to traffic-related air pollutants. Elizabeth will apply the assessment to data from the National Enhanced Cancer Surveillance registry to produce individual estimates of chronic exposure to air pollutants, with a special emphasis on traffic-related pollutants. The research will help improve understanding of the impacts of air pollution, particularly the relationship between chronic exposure to air pollution and lung cancer, an area that hasn’t been researched extensively.
