Question

What are the main causes of air and water pollution?

Answer 1

Hint: Water and air pollution are a major problem globally. Air is essential for life itself. Without it we could survive only a few minutes. It constitutes the immediate physical environment of living organisms.

Complete answer: The atmosphere is differentiated into four distinct layers: Troposphere, stratosphere mesosphere, and thermosphere.
1. Air pollution consists of gases, Liquid-liquid, or solids present in the atmosphere in high enough levels to harm humans, other organisms, or materials.
2. Air pollutants may be either primary or secondary.
3. The main sources of air pollution are automobiles, motor vehicles throughout the urban areas, they emit hydrocarbons carbon monoxide lead nitrogen oxide, and particulate matter
in strong sunlight, they are converted into photochemical pollutants.
4. In addition, the diesel engine’s when misused or badly adjusted are capable of emitting black smoke, industries, combustion of fuel to generate heat and power, produces smoke, sulfur dioxide, nitrogen oxide, and fly ash.
5. Petrochemical industries generate hydrogen fluoride, high hydrochloric acid an organic halides,
6. Domestic sources: Domestic combustion of coal, wood, or oil is a major source of smoke, dust, sulfur dioxide, and nitrogen oxides.
7. Tobacco smoke: The most direct an important source of air pollution affecting much health
Even those who do not smoke make inhales produced by others known as passive smoking.

Cause of water pollution:
1. Water is a precious resource and is getting polluted day by day due to excessive and careless use, so the percent of available drinking water is reducing.
2. Principal sources of water pollution are domestic waste, sewage system, solid waste, industrial waste, acid rain, oil industry and aqueduct plunge.
3. Solid waste causes obstruction inflow of water. It leads to water as well as air pollution
industrial waste containing paper waste, rubber, metallic waste is drawn directly into water thus polluting it.

Note: When you think of environmental pollution, it typically comes in seven different forms. These consist of air, water, land, radioactive, thermal, light, and sound pollution.
