Contamination vs. Pollution: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 28, 2023
Contamination refers to making something impure by exposure to harmful substances, while pollution is the introduction of contaminants into the environment causing adverse change.

Key Differences

Contamination is the presence of an unwanted substance in another substance, making it impure. Pollution, however, refers to the introduction of harmful substances into the natural environment, causing potential harm to ecosystems.
