If possible we can live in less polluted areas but this is not often a choice for most people. We may not have control as individuals over the air where we live, but we can exercise some control through group effort to reduce emissions and improve air quality everywhere.
Besides outdoor pollution, many people are exposed to workplace dust, chemicals and fumes, which increase the risk of chronic bronchitis, emphysema and COPD. A number of industries appear to be problematic including coal and gold mining, the cotton textile industry, occupations involving cadmium, isocyanates and fumes from welding. In some professions the risks are estimated to be equivalent to that of smoking. The negative effects of dust exposure and cigarette smoke exposure appear to be additive or possibly more than additive.
