E.1. Introduction

  • Pollution is described as the introduction—or excessive introduction—of specific substances into the physical environment (air, water, or land), rendering it less suitable or completely unsuitable for sustaining life.
  • The agents responsible for this degradation, known as pollutants, are materials or factors that negatively impact the natural state of any environmental component.

[Types of Pollution]

Classifications of Environmental Pollution

According to the form in which they persist after release into the environment.

(i) Primary Pollutants: These are substances that remain in the same chemical form as when they were initially released into the environment.Examples: Plastics, DDT.
(ii) Secondary Pollutants: These are formed by interaction among the primary pollutants. For example, peroxyacetyl nitrate (PAN) is formed by the interaction of nitrogen oxides and hydrocarbons.

According to their existence in nature.

(i) Quantitative Pollutants: These occur in nature and become pollutant when their concentration reaches beyond a threshold level. Example: carbon dioxide, nitrogen oxide.
(ii) Qualitative Pollutants: These do not occur in nature and are man-made. Example: fungicides, herbicides, DDT etc.

According to their nature of disposal.

(i) Biodegradable Pollutants: Waste products, which are degraded by microbial action. Example: sewage.
(ii) Non-biodegradable Pollutants: Pollutants, which are not decomposed by microbial action. Example: plastics, glass, DDT, salts of heavy metals, radioactive substances etc.

According to origin

(i) Natural
(ii) Anthropogenic
