Then, the research modeled emissions of pollutants originating with diesel exhaust and the exposures of individuals in the two case study areas, focusing on particulate matter.

Lung cancer remains a pressing worldwide public health problem.
New techniques of molecular and cellular biology may also provide markers for studying the effects of air pollution as well as the longitudinal process of carcinogenesis, for screening, and for use in intervention trials. The long-range goals are to describe and validate markers for lung cancer and effects of air pollution, and to use these markers to further characterize the respiratory effects of air pollution and quantitative lung cancer risks after cessation of smoking. In this pilot project, methods will be developed and feasibility will be assessed for using biomarkers in exfoliated respiratory tract cells from sputum in molecular epidemiologic studies. Sputum containers, instructions and questionnaires were sent to each household. Participants were given 2-3 weeks from the date the kit was mailed to return the container and questionnaire.
