Pollutant Information: Selenium
Category: Heavy metals and base cations
Acute exposure to selenium by inhalation results in respiratory effects such as irritation to the mucous membranes, severe bronchitis and bronchial pneumonia. Selenium emissions have declined by 79% since 1990. The majority of selenium emissions in earlier years were from coal combustion, and, although emissions have declined with coal use, it remains a significant source in 2014. Only trace amounts are emitted by the combustion of petroleum-based fuels.
