Firefighters hаve а pоtentiаl fоr expоsure to different types of chemical compounds by inhalation of particulate matter, gases, and vapors during the course of their work. A large number of known (e.g., arsenic, asbestos, benzene, formaldehyde and silica) or suspected (e.g., acetaldehyde, naphthalene, polychlorinated biphenyls, and toluene diisocyanates) human carcinogens have been detected in smoke at fires, several of which are known to cause lung disease and airway disorders (LDAD). Exposure to these chemicals may vary widely among firefighters depending on the type of work activities, time spent at fires, as well as state differences which regulate the type of protective respiratory equipment used. You are interested in determining if there is an increased risk of lung disease and airway disorders (LDAD) among firefighters in Florida (exposed) compared to Massachusetts (unexposed). Smoking status may be an important confounder in your analysis.
