The researchers found that exposure for more than 12 months to higher levels of nitrogen dioxide and fine particulate matter of less than 2.5 micrometres more than doubled the risk of hospitalization for pneumonia in adults aged 65 and older. Exposure to sulfur dioxide was not associated with an increased risk of hospitalization.
