What type of pollution is a colorless and odorless toxin that is formed when coal, charcoal, natural gas, or oil undergo an incomplete combustion?
Explanation
Answer: C - Carbon monoxide is a colorless and odorless toxin that is formed when coal, charcoal, natural gas, or oil undergo an incomplete combustion.
Key Takeaway: Carbon monoxide, or CO, is a highly-toxic gas that is formed when coal, charcoal, natural gas, or oil undergo an incomplete combustion. In humans and other animals, CO binds to the hemoglobin in the blood, severely restricting respiration. In households, water heaters, stoves, and other cooking fires can emit carbon monoxide. Because it is colorless and odorless, it is often referred to as a “silent killer.”
