Pollution may be air, water and soil. These have lot of impacts on the human life. Air we breath, water we drink and food we eat., where there is contamination of toxic  chemicals leading to cancer of the bones, skin, longs etc.   Sound pollution may have significant on human heart & nervous system.

Dear Madhukar, 

Thanks a lot for your reply.

Pollution is a degradation of the environment whatever its physical, chemical or biological nature. It has an impact on the physiology and behavior of the organisms exposed or on the characteristics of the biotopes consequently on the composition and the structure of the populations.

Also what is difference between pollution and contamination?

make inconsistency to live and abolish our attitude

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.

Impact: It makes the world unfit for living for all living-beings.

Dear Selvam, 

Thanks a lot for your reply. It's good. 

Best regards!

A great subtlety between pollution and contamination.

Contamination contaminates where pollution degrades. A contaminant may be classified as a pollutant based on, inter alia, its amount in the environment, potential toxicity, bioavailability, and interaction with the environment.

Thus Pollution is the introduction of a harmful substance to the environment and is usually caused by people

Contamination is when an undesired material or impurity is in something.

Dear Fadhel,

Thanks a lot for your reply. But what is the legal definition of pollution, contaminant, ...

With my best regards!

Adel

Substances that were not present in the air, soil and water before human activities started on this planet.

The impact of pollution is damage to health of ourselves and anything that is living.

A pollutant is an agent that may be of a physical, chemical or biological nature causing ecotoxicological effects. The subtlety between polluting and contaminating words requires some attention because a contaminant is an element that has been added into a medium. A pollutant can be a contaminant if it does not fit as a base element in an ecosystem or environment.

Dear Colleagues,

Good Day,

Dear Colleagues,

Good Day,

"Types and Causes of Pollution

The term pollution refers to the act of contaminating ones environment by introducing certain hazardous contaminants that disturb the ecosystem and directly or indirectly affect the living organisms of that ecosystem. Pollution in general is the activity of disturbing the natural system and balance of an environment.

The increase in the pollution over the years by man has caused severe damage to the earth’s ecosystem. It is responsible for global warming which is leading to the end if all the lives on earth. Over the years there is an extreme increase in the rate of human diseases, and death rate of various animals and plants on earth, and that is all because of the pollution caused by man himself.

 There are many types of pollution, but four of them have the most perilous affect on our lives. Following are the four most dangerous types of pollution and their causes:

• Air Pollution
• Soil Pollution
• Water Pollution
• Noise Pollution"...

Please, go to the attached website link to read the Causes of these Pollution, and for more information...

Dear Hazim, 

Thanks alot for your interesting reply.

Pollution denotes the presence of impurities  like dirt, silt, organic matter, mineralos, acidity, alkalinity and objectionable colour, odour or taste.  Although pollution is not necessarily a health hazard, always, it is either accompanied by contamination which is a health hazard.  - Textbook of Social and preventive Medicine,  Thanks to Dr. M.

Dear Colleagues,

Good Day,

"Causes of Water Pollution

Urbanisation

As more and more people move into cities and towns, a number of factors cause pollution:

1- the physical disturbance of land due to construction of houses, industries, roads, etc.;

2- chemical pollution from industries, mines, etc.;

3- inadequate sewage collection and treatment;

4- increase in fertilisers to grow more food. This results in an increase in nutrients (nitrates and phosphates) in the water which causes enhanced plant growth (algal blooms). When this plant material dies and decays the bacteria uses the oxygen in the water. This lowering of oxygen levels results in the death of other water life that needs oxygen to survive, eg. fish, etc. This process is called eutrophication;

5- litter, which causes disease and has a negative visual impact.

There are many other causes of pollution such as 

Deforestation

Damming of Rivers

Destruction of Wetlands

Industries

Mining

Agriculture

Energy Use

Accidental Water Pollution."...

Pollution is the effect of undesirable changes in our surroundings that have harmful effects on plants, animals and human beings. This occurs when only short-term economic gains are made at the cost of long-term ecological benefits for humanity.

Dear Dr. Arvind,

Thanks so much for your interesting reply. I agree with.

With my best wishes!

Dear Dr. Adel Queslati,

Please also have a look at this useful ResearchGate link for details.

https://www.researchgate.net/publication/228243884_Environmental_Pollution_Its_Effects_on_Life_and_Its_Remedies

Best of luck!

Dear Adel Queslati,

the pollution is a relatively new term. for the impurity of air, sol, water, plants, etc.

Firstly, you can See the synonymes:

https://dictionnaire.reverso.net/anglais-synonymes/pollution

Secondary, now in ecology it exist the term "impact", and it need to distinguish Accidental pollution or not, and other types:

acoustique, industrial, etc.

Best regards,

Dear Adel,

Pollution of the environment is usually defined as the contamination of the environment. there are different types of pollution which are air, water and soil pollution. Meaning each of these media (air, water and soil) can be contaminated by action and interaction of human activities and industrial activities with these media. Best regards.

Air, water and soil all will become worst and thereby it will become difficult to survive on this planet.

Interesting discussion.

Pollution is the introduction of contaminants into the natural nvironment that causes adverse change.

Major forms of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.

Effects

Human health

An October 2017 study by the Lancet Commission on Pollution and Health found that global pollution, specifically toxic air, water, soils and workplaces, kill nine million people annually, which is triple the number of deaths caused by AIDS, tuberculosis and malaria combined, and 15 times higher than deaths caused by wars and other forms of human violence. The study concluded that "pollution is one of the great existential challenges of the Anthropocene era. Pollution endangers the stability of the Earth’s support systems and threatens the continuing survival of human societies.

Environment

Pollution has been found to be present widely in the environment. There are a number of effects of this:

· Carbon dioxide emissions cause ocean acidification.

· The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

· Invasive species can out compete native species and reduce biodiversity..

· Nitrogen oxides are removed from the air by rain can change the species composition of ecosystems.

· Smog and haze can reduce the amount of sunlight received by plants

· Soil can become infertile and unsuitable for plants. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

· Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.

I agree with Mr.Dhiaa Neama Jabbar .

Water, air and agricultural land are getting polluted and are very harmful to human health. We can say our future is in Danger and difficult to survive.

Dear Dr. Imran,

Thanks so much for your interesting reply.
