Environmental pollution


The environmental pollution is the process by which the land , the water , the air or other parts of the environment to become dirty and unsafe or inappropriate for use or as a means for populations of habitat. The contamination arises when given the introduction of a contaminant in the natural environment . Things as simple as light, sound and temperature can be considered pollutants when they are introduced artificially and in high proportions into an environment. Toxic pollution affects more than 200 million people worldwide, according to the organization “Pure Earth “, an environmental organization nonprofit. In some places around the world where contamination rates are extremely high, babies can be born with defects of birth and hope of life can be so low that it can reaching 45 years of age due to cancers and other diseases derived from pollution.


What is environmental pollution?

It is the introduction into the environment of a series of physical , biological or chemical agents that produce a series of alterations that affect the health, well-being and habitat of the animal and plant life that inhabits the planet.

Causes of environmental pollution

There are many causes that can lead to environmental pollution, taking into account that any agent that is in abundant concentrations could potentially contaminate a medium by altering its structure and function. Among the most common causes we can mention:

  • Chemical pollutants:  These are compounds that are derived from the chemical industry such as, for example, toxic products, acids, detergents, petroleum derivatives and pesticides.
  • Physical pollutants:  We can mention within this group heat, fire, radioactivity.
  • Biological pollutants:  They are all those organic waste that when decomposed in the earth ferments producing damage. For example, factory waste, excrement, sawdust, etc.
  • Radioactive contamination:  It is the type of contamination that is derived from radioactive materials such as uranium that is used in hospitals and research institutions, waste from submarines and artificial satellites.
  • Thermal contamination:  It is the high temperature produced in the water that reduces its solubility .

Sources of environmental pollution

The main sources that produce pollution in the environment are:

  • The traffic of cars
  • The combustion that occurs in different types of factories and boilers that generates constant combustion in their furnaces and the wastes that are produced as a result of the These gases are mainly composed of CO , CO2 and H2O , compounds of sulfur and carbon.
  • Burning of fuel by cars that produce CO2.
  • Industrial activities .
  • Industry mining
  • Hazardous waste from hospitals and factories.
  • Pollution by loud sounds that affect the lives of the people around.

Effects edit

There are many and different effects that environmental pollution has both in the long and in the short term on the health of the inhabitants of a place. The increase in the number of respiratory diseases , lung cancer and heart disease are some of them. Among the groups most vulnerable to the effects of pollution are young children, older adults , low- income families and those who are already sick . Pollution has been causing a great deal of damage to ecosystemsand in the daily life of the human being through the progress and action of man . At the same time, flora and fauna also suffer from pollution and for this reason many of them are in danger of extinction .


The consequences that environmental pollution brings to human beings are mainly due to the emission of gases that are toxic. These cause strong eye and respiratory irritation, this because smoke and dust particles enter the body and lodge in the lungs . In the climate and the environment, environmental pollution produces CO2 that affects the greenhouse phenomenon . Finally, the consequences for flora and fauna are serious and it is reflected in the growth of animals, it can even lead to the extinction of species .

Prevention of environmental pollution

Some of the simplest methods to prevent environmental pollution are:

  • Reduce fumes caused by cars.
  • Save energy.
  • Use products that are friendly to the environment and the garden.
  • Do not use scent spray to spray homes or offices.
  • Recycle and use recycled products.
  • Plant new trees.


The types of pollution are classified according to the part of the environment that they pollute or affect. The main ones are: water, air, soil, thermal, acoustic, light and radioactive.

Examples of environmental pollution

The noise generated by cars, companies and places where music has high volume levels are an example of noise pollution . A clear example of contamination of the water is when ships are spills of fuel into the sea, resulting in the death of many aquatic species. The smoke some factories produce various aerosols and used in homes are examples of pollution of the air .
