Which of the following are not the source of air pollution?

Which of the following are not the source of air pollution?

(c) windmill Windmill will not release any sort of gas into atmosphere hence it is not considered as a source of air pollution. Air pollution happens when harmful gases and particles are released into the air . Windmill helps convert wind into energy that can then be used for various purposes.

Which gas is not found in environment?

Radon (Atomic number 86) is a radioactive substance produced due to decay of Radium-226 found in Uranium ore. This is not present in the atmosphere.

What gas causes pollution?

Gases that lead to air pollution include carbon, nitrogen and sulfur oxides. While some of these gases occur naturally, like carbon dioxide in the expulsion of air from the lungs, the serious polluters come from the burning of fossil fuels: coal, oil and natural gas.

Which is not a natural source of pollution?

Natural pollution comes from natural sources like release of methane by cattle and paddy fields, carbon dioxide from plants and animals, dust storms, nitrogen oxides, ozone, volcanic eruptions, emission of natural gas, soil erosion, ultraviolet rays, etc. Mercury is not a cause of natural pollution.

What are sources of air pollution?

There are four main types of air pollution sources:

• mobile sources – such as cars, buses, planes, trucks, and trains.
• stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
• area sources – such as agricultural areas, cities, and wood burning fireplaces.

Which gas is not found in air?

Radon is a radioactive element and is not found in the atmosphere. It is found in rocks containing uranium ores and is produced by the radioactive decay of radium.

Is co2 a greenhouse gas?

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities.

Which of the following is not cause of pollution?

Detailed Solution. Solar energy is the energy derived from the sun. No air or water pollution is given off when solar panels are used for energy production. Solar energy is an alternative for fossil fuels as it is non-polluting, clean, reliable and renewable source of energy.

Which of the following is not a primary pollutant of air pollution?

1. Which of these is NOT a primary pollutant? Explanation: Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source.

What are the 4 sources of air pollution?

What are the main sources of air pollution?

Most air pollution, harmful gases and particles in the air, affecting national parks is created outside park boundaries. Types of Sources. There are four main types of air pollution sources: Mobile, stationary, area, and natural sources all emit pollution into the air.

Which is the correct definition of air pollution?

(a) When air is contaminated by unwanted substances which have a harmful effect on both the living and non-living, it is referred to as air pollution. (air pollution, harmful, living, unwanted, non-living, pollutants). (b) Many industries are responsible for causing air pollution.

Why is acid rain a nonpoint source of pollution?

It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

What kind of chemicals are in natural gas?

In relation to natural gas, these include mostly VOCs followed by n-hexane, BTEX group of chemicals (benzene, toluene, xylenes and ethylbenzene), and sometimes hydrogen sulfide at high concentrations.
