Tag: ways to reduce air pollution

Carbon monoxide is basically formed when an object is burned. Methane, which is a natural gas produces  CO after oxidation. Methane, produces less CO as compared to other units of gas. Incomplete combusion results in creation of poisonous CO. It occurs when supply of oxygen is poor. 

A plant, like an animal, needs energy. Plants have a process called photosynthesis to transform light energy into chemical energy (glucose sugar). Plants produce oxygen during photosynthesis, the oxygen is derived from the water it intakes and not from the carbon dioxide. 

Governments have already taken action against air pollution by introducing green energy. Like wind energy, solar energy and renewable energy to minimize burning of  fuels which cause heavy air pollutions.

Use of public mode of transportation, conservation of energy, the concept of Reduce, reuse and recycle are the solutions to air pollution.

The concept of 'Reduce, reuse and recycle helps us to minimize the dependence on producing new things. 

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuels, fuel oils, or coal. The largest part of most combustion gas is nitrogen. water vapour (except with pure-carbon fuels), and carbon dioxide (except for fuels without carbon); these are not toxic or noxious. A relatively small part of combustion gas is undesirable noxious or toxic substances, such as carbon monoxide (CO) from incomplete combustion.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Carbon monoxide is an air pollutant. It is found in cigarette smoke and emissions from motor vehicles, industrial processes, and poorly ventilated combustion sources.

In adsorption method,the polluted air is passed through porous solid adsorbents kept in suitable containers. The gaseous pollutants are adsorbed at the surface of the porous solid and clean air passes through.

In absorption method,the polluted air containing gaseous pollutants is passed through a scrubber containing a suitable liquid absorbent. The liquid absorbs the harmful gaseous pollutants present in air.
