Pollutants and its impact on ecology and environment

Shubhaseesh Srivastava

Abstract


Abstract

Pollution is the result of unfavourable changes in our environment that have a negative impact on humans, animals, and plants. Pollutants are any compounds that are produced by human activities that are present in greater quantities than they would naturally and have a specific impact on the environment.

The degree of a pollutant's harmful impact on human health depends on its type and concentration. Impurities like CO, SO2, and NO that are released into the environment directly from their source are considered primary pollutants. When secondary pollutants like PAN (peroxy acetyl nitrate), petrochemical smog, and formaldehyde are created when pollutants like HC, NO, and O3 mix in the atmosphere (moisture, sunshine).

Pollutants can be categorised as either degradable, slowly degradable, or non-degradable from an ecological point of view. There are several pollutants that have a big impact on human illness. Among these, Particulate Matter (PM), which has a range of sizes but has a very small diameter, enters the respiratory system by inhalation and causes cancer, reproductive and cardiovascular disorders, as well as problems with the central nervous system.
