What Does PI Stand For?

PI stands for Pollution Index

The Pollution Index (PI) is a quantitative measure used to assess the level of pollution in a specific area or environment. It evaluates various pollutants, such as particulate matter, nitrogen dioxide, sulfur dioxide, and carbon monoxide, providing a comprehensive overview of air or water quality. The PI helps policymakers, researchers, and the public understand pollution trends, make informed decisions, and implement necessary environmental protections. A higher PI indicates greater pollution levels, while a lower PI signifies better environmental conditions.
