Air Pollution

Front 1

Air pollution is one of the major problems of the present world.

There are so many causes that can pollute the air completely and spread ---.

On the basis of the --- it can be distinguished into different types.

Mainly the type of the air pollution depends on some of the --- and most of them are composed of ---.

Some important and common types that have great effect on the air of the environment and they also take part in spreading different types of dangerous diseases.

TYPES OF AIR POLLUTION

Smog:

The first type of the air pollution is the smog.

It is defined as when the smoke present in the atmosphere after emitting from different sources is combined with the --- present in the air, a mixture formed that is referred to as smog.

Basically different types of ---or--- are responsible for the formation of the smog.

fog

factories or the industries

Front 3

Smog....

When the industries do their production from different materials, they can use different types of chemicals for the ---,---or--- processes, as a result these chemicals can produce --- that can emit in the form of the smoke from the chimney of the factory and form a --- and cause different harmful diseases.

Living in the smog is equal to the living with ---;

it can cause ---.

Green House Effect:

Another type of the air pollution is the green house effect.

It is that type of air pollution that is formed due to the ------.

It is charactered when the gases called as green house gases when move upward and combine with the atmosphere and then return back to the earth and destroy different types of things such as ---4 etc.

Front 5

Green House Effect....

These green house gases are basically --- in number and they are;

---6.

Basically the pollution is raised due to the burning of ---,

it is very harmful for the ---

and can also cause ---.

Accidental air Pollution:

It is the type of pollution that is characterized due to the causes that are ---.

Commonly it is defined as the type of air pollution that is generated due to the different types of fuel consumption by the ---

or when ---- different types of gases are evolved that are mixed with the air and pollute the air.

Sometimes this pollution is also spread due to the ---

or different types of ---of the manufacturing plants.

accidentally in nature

blasts in the furnaces

Front 7

Industrial Air Pollution:

Another type of air pollution that pollutes the environment as a result of the --- is called as industrial pollution.

Commonly it is characterized due to the working of the ---

and also the different plants that are used to manufacture different types of ---or---.

Back 7

industrial processes

thermal plants

fertilizers or pesticides

Front 8

Industrial Air Pollution.....

The reactions that are used to produce different types of building material such as ---or--- etc. also encourage the production or --- materials for producing air pollution.

On the whole the air pollution due to the --- is called as industrial pollution.

Different type of --- also contributes in that type of pollution.

cement or steel

industrial wastes

atomic units

Front 9

Transport Related Air Pollution:

It is that type of air pollution that is characterized due to the ----ing by different types of vehicles used for transportation.

As fuel such as petrol or diesel burnt in the engine can emit different types of --- in the form of smoke.

This pollution can cause different types of ---.

Sources of Air Pollution

The combustion of gasoline and other hydrocarbon fuels in ---3 produces several primary pollutants:

---3,

as well as large quantities of particulates, chiefly---.

Back 10

automobiles, trucks, and jet airplanes

nitrogen oxides,

gaseous hydrocarbons,

and carbon monoxide

lead

Front 11

In the presence of sunlight,

nitrogen oxides combine with hydrocarbons

to form a secondary class of pollutants,

the ---, among them ozone and the eye-stinging --- (PAN).

Back 11

photochemical oxidants

peroxyacetylnitrate

Front 12

Nitrogen oxides also react with oxygen in the air to form ---, a foul-smelling brown gas.

In urban areas like Los Angeles where transportation is the main cause of air pollution,

nitrogen dioxide --- the air,

blending with other contaminants and the atmospheric water vapor, to produce ---.

Although the use of --- has reduced smog-producing compounds in motor vehicle exhaust emissions,

studies have shown that in so doing the converters produce ---, which contributes substantially to global warming.

Front 14

In cities, air may be severely polluted not only by transportation but also by the burning of fossil fuels (oil and coal) in ---4 and by the incineration of ---.

The massive combustion produces tons of ---,---ae responsible for the gray smog of cities like New York and Chicago,

along with enormous quantities of --- (which also may be result from burning coal and oil).

These oxides......

rust ---,

damage ---,

decompose ---,

tarnish ---,

and kill ---.

Air pollution from cities also affects ---for many miles downwind.

Every industrial process exhibits its own pattern of air pollution. Petroleum refineries are responsible for --- and --- pollution.
