A pollutant or novel entity[1] is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts).
For example, household activities such as cooking and heating with dirty technologies, and lighting with kerosene, emits a range of health harmful pollutants indoors, while activities such as high temperature combustion in vehicles, industries and power generating facilities contribute to ambient air pollution.

Water is greatly polluted these days and the harmful pollutants present in it are causing this. The runoff from industries, agricultural fields, and even urban areas contribute to it largely. For instance, the industrial waste consists of toxic contaminants which hamper the quality of water. Moreover, these pollutants also cause the growth of algae...
Soilalso has a lot of pollutants which makes it very tough for the soil to remain fertile. Again we have the industrial sources contributing to it. Moreover, there is no proper disposal of the toxic chemicals materials so they end up in the soil. Moreover, some common examples of soil contaminants are asbestos, PCB’s, lead, pesticide, and herbicide...
The airwe breathe these days is heavily polluted, more than ever. One of the major air contaminants is burning fossil fuels. This happens due to factory emissions and the use of automobiles. When one burns fossil fuels, smog gets formed as well as a thick layer containing particulate matter which encloses large zones in it. Furthermore, air polluti...
Lightpollution is also a very damaging type of pollution which needs to be emphasized upon. It means when there is a lot of light present in any areas, this generally happens in urban and densely-populated areas. The light contaminants prevent the people from seeing the features of the sky at night clearly. In addition, it also obstructs the activi...
Noise pollution is on the rise, especially in urban areas. Generally, humans and their activities make noises pollution. These noises are so loud they disrupt the quality and functioning of life. These are horns of automobiles, loudspeakers, firecrackers, electrical appliances, and more. They hamper the movement of sea mammals like whales and dolph...
Oct 17, 2024 · pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution, water ...
Feb 17, 2023 · Some of the significant sources of air pollution are given below: Burning of fossil fuels such as coal, oil, and natural gas. Exhaust from automobiles and industries. Indiscriminate cutting of trees (deforestation) Wildfires resulting from burning stubble and farm residues. Release of methane from microbial decay.
Air pollutants overview. Air pollution describes a collection of airborne pollutants that contribute to our air quality. The term “pollutants” recognizes that these substances are undesirable because of their impact on human health, the environment and the economy. These air pollutants are all very different.
