Long-term exposure to chemical hazards such as silica dust, engine
exhausts, tobacco smoke, and lead (among others) have been shown to
increase risk of heart disease, stroke, and high blood pressure. It can

obstructive pulmonary disease (COPD) and lung cancer. Construction
workers have a high risk of developing these diseases because many
common construction tasks can create high dust levels.
