What are chlorofluorocarbons (CFC's)?

300

an important heat-trapping gas, or greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and from natural processes like volcanic eruptions.

What is carbon dioxide?

300

This system in cars reduces NOx, CO and can be damgaged by leaded gasoline.

What is limestone?
400

an air pollution control device which uses a liquid to remove contaminants from a gas stream. The removal process is achieved by bringing the gas stream into contact with the liquid, which facilitates mass transfer of the contaminants into the liquid.

What is a wet scrubber?

500

This neurotoxin is released in coal and oil production, and gold mining. Most exposure is from eating fish, amalgam-based dental fillings, or exposure at a workplace. In fish, those higher up in the food chain generally have higher levels of the toxin, a process known as biomagnification.
