Types of pollution ,Pollution control & How to protect


Types of pollution ,Pollution control & How to protect


The Pollution is of various types, and It needs different type of Pollution control
1 Air Pollution. (It needs air pollution control
2 Water Pollution. (It needs water pollution control )
Noise Pollution (It needs noise pollution control )
4 Environmental Pollution (It needs environmental pollution control )
5 Soil Pollution (It needs soil pollution control )
Gaseous Pollution (It needs gaseous pollution control )
1. Air Pollution and air pollution control
Impurities are mixed into the earth atmosphere or near the earth surphace. Impurities include natural or artificial gases, as well as other particles.
Lower atmosphere called as tropospherecleanses these air pollutants. Rainfall also help to remove these impurities.
But rainfall converts into acid raindue to some pollutants like sulfates, nitrates etc. which can damage ourenvironment also the pollutants which mix in the upper atmosphere can causedamage to the ozone layer.
Naturalcontamination agents are salts & particular dust & gases.
ArtificialContamination agents are smoke & industrial Gases, municipal waste,household waste . Automobile emissions , aircraft emission & rocket jet combustion.
Certain gases likefluorocarbon compounds used in spray cans affect the ozone layer in thestratosphere. 
Also there aretrace gases & metals emitted in industrial operations.
Effects of air pollution
Air pollution affects health, damages agriculture, changes climate .
The pollutionproblems started becoming serious with the beginning of industrial revolution after the burning fuel like coal & oil began. Theaddition of motor vehicles added to the seriousness of the problem. These causedsome serious air pollution accidents in the Meuse valley in Belgium, in1948 Donora, Pennsylvania & in 1952 in London. These resulted in the deathof several persons
Different types of Air pollutioncan be specified in the following.
Gaseous -Carbon monoxide particulate smoke, pesticides, Aerosol sprays..
Inorganic - Hydrogen fluoride.
Organic - mercaptans.
Oxidizingsubstances - Ozone.
Reducingsubstances - Oxides of sulfur.
Radioactive substance-
Inertsubstance - Pollen or fly ash.
ThermalPollution - Heat from Nuclear Power Plants
Indoor air Pollution -Radon gas from soils & structure. Also 
household chemicals in indoor air.
The toxic gas released into the air due to accidentcan be disastrous. The gases released Bhopal gas tragedy in 1984 , Killed 2000 People, in industrial Accident.

The toxic gas released into the air due to accident can be disastrous. Be the first to comment - What do you think?
Effects of Air Pollution to
1. Humans .
2. Animals
3. Vegetation
4. Material
5. Atmospheric System
Effects of Air pollution an Humans & Animals
Most of people spend their time indoors, there is Air pollution in homes, offices, shopping malls & areas.
Air Pollution mainly damages the Respiratory system.
This damages can be studied through scientific ways.
  1. Clinical
  2. Epidemiological using the health records
  3. Theological using animals
The Effects of Air Pollution on Human & Animals depend on exposure time.
If the time of Exposure is small in the high concentration the effect will be mild.
But if the exposure is for extended period, in the low concentration, the effect can be bad.
Effects of Air Pollution on vegetation is of many kinds. Sulfur dioxide can damage crops & trees. Hydrogen fluoride & nitrogen dioxide can damage ornamental plants & fruit trees. Ozone & ethylene cause damage to vegetation.
Effect of Air pollution to the Materials it damage ferrous Metals Nonferrous Metals like Aluminum, Copper, Silver, Nickel &
Building Materials -Paint, leather, Paper, Textile, Dyes, Rubber, 
Ceramics
Effect of Air Pollution to the Atmosphere.
It changes the dynamics of atmosphere through the long & short waveradiation Processes
Carbon dioxide increases the temperature of surface due to which thetemperature of the atmosphere will increase ,cause serious environment effects.

Dangerous gaseous pollutants

Sulfur Dioxide is one of the most dangerous gaseous pollutants for the mankind The lungs and mans respiratory system are affected by it . It causes strong irritation to the eyes and skin. It even destroys the enamel on teeth. Many effects of this gas on man are permanent and irreparable.
Burning of oil and coal are the main reason for the production of this gas. Different kinds of coal and oil have different amounts of sulphur That is reason more sulphur dioxide will produce from the burning. If coal with a high sulphur content is burned,more sulpur dioxide will be produced. and enter the atmosphere as sulphur dioxide gas.
Very large number of residents of Metro towns are living in the polluted air Which is killing the people, Many office goers as well as school are carrying the inhalers To control frequent wheezing and asthma attacks. I myself keep on coughing all night on in the office . I know it is very bad but nothing can be done. This is due to the air pollution which is killing people and bringing down the quality of life across the metro towns .
A survey has shown that majority of people living in Delhi suffer from cough, eye irritation ,Sore throat, shortness breath and poor lung functioning,

Polluted Air is killing people
Hundreds of office goers in the metro towns are living their daily routine life In the normal way. But they carry an inhaler or any other help to control their frequentasthma attacks. They cough all day in the office or workplace .Although it is very irritating, but they can not do anything to help it.
eye irritation ,cough ,sore throat ,breathlessness, poor lung functioning.
This problem is due to the effect of polluted air in the Metro cities on the health.The polluted air is actually killing people. One feels irritated, tired, ill all the time. A survey has shown that pollution has effect on majority of people suffer from eye irritation ,cough ,sore throat ,breathlessness, poor lung functioning.
