Environmental Pollution


Environmental pollution is the release of chemical waste that causes detrimental effects on the environment Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.

The types environmental pollution

The environmental pollution is usually classified by environment and are as follows:

1. Air pollution,

2. Water pollution

3. Land pollution.

The society is now concerned about specific types of pollutants like noise pollution, light pollution, and plastic pollution.

Air Pollution Chemistry :

Some air pollutants that are released into the atmosphere by man-made activities pose environmental and health risks directly. These primary pollutants include carbon monoxide, particulate matter, nitrogen oxides and lead, emitted from exhausts of road vehicles. Additional impacts, however, result from the conversion of primary pollutants by a complex series of chemical reactions in the atmosphere, to secondary pollutants, many of which are potentially more harmful than their precursors. Since much of the pollutant chemistry is driven by the presence of sunlight, the secondary products are commonly referred to as photochemical pollutants.

Major Causes of environmental pollution

The industrialization and urbanization are the major causes for environmental pollution. For the sake of development, developed and developing nations are in era of industrial revolution and human has continued to introduce hazardous materials into the environment at an alarming rate for their electric generation, mining and exploration, agricultural activities, burning of fossil fuels etc.

Effects of air pollution

In many research it has been observed that higher air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose and throat. The air pollution can also cause worsening of existing heart problems, asthma, and other lung complications. The air pollution cause many environmental effects in addition to the effects on humans and animals.

The acid rain contains high levels of nitric and sulfuric acids that are created by oxides and sulfur oxides released into the air by the burning of fossil fuels. Acid rain may damages trees and acidifies soils and water bodies, making the water too acidic for fish and other aquatic life.

Effects of water pollution

Water pollution is a serious matter to humans, animals, and aquatic life. Its depend on which chemicals and garbage are being dumped where legally or illegally. Bodies of water that are near urbanized areas tend to be heavily polluted by dumbing of garbage and chemicals by industrial plants, health centers, and individuals.

Effects of land and soil pollution

It has been found in many studies that land and soil pollution has substantial consequences for humans, animals, microorganisms and aquatic life. Contaminated land and soil can cause various problems on the skin, respiratory problems and even different kinds of cancers.
