Those gases which are released from the chemicals of various industries are called industrial gases. Commonly it contains carbon-di-oxide, carbon-mono-oxides mono-oxides of nitrogen. These gases are the principal source of atmospheric pollution,greenhouse effect and ozone layer depletion. Sulphurdioxide, carbon dioxide, carbon monoxide and other gases related to them are also released from industries. These gases react with ozone layer and gives sulphur trioxide. Dust, smoke released from industries cause air pollution. They hinder muscular functioning. It affects mental functioning as well.

Acid rain
Acid rain

Acid rain

When the various gases like CO2, SO2, NO2, combine with rain water then their respective acids will be produces. These acids will react on the ground along with rain water in the cocktail form. This process is called acid rain. In the atmosphere these gases react with water vapour and formed their corresponding acids like H2CO3, H2SO4, and others. When rainfall occurs these acids get mixed with rain and forms acid rain.

  1. The acidity of soil increases which cause the reduction of productivity of soil.
  2. The acidity of water bodies increases which cause the decline in population of aquatic organism.
  3. The historical monuments damages because of acid rain.

Effects of industrial gases

  1. Many of the gases left by industries are greenhouse gases and they cause global warming.
  2. These gases form photochemical smog which causes eye itching and negative effect on plant growth. The smog reduces the transparency of atmosphere and it creates a problem for pilots to land planes
  3. Some of the gases left by industries also cause ozone layer depletion.
  4. The materials given off by industries show an adverse effect on human health.

  • Those gases which are released from the chemicals of various industries are called industrial gases.

Very Short Questions

Nitrogen oxides and sulphur dioxide gases are carried high into the air; they dissolve in water droplets in the clouds. The clouds may be carried many miles. They fall in the form of acid rain.

If the green-house gases were not found on the atmosphere, the heat would not be trapped on the earths surface. As a result the remperature of the earth would be much less. If the earth was very cold, it would be covered by ice and there wouldn't be the existance of life.

In the process of industrial production, different gases like oxides of carbon and oxides of sulphur are formed. In the atmosphere these gases react with water vapour and form their corresponding acids like H2SO4 etc. When the rain fall occurs, these acids get mixed with rain and forms acid rain.

Effect of increasing in carbondioxide gas in the atmossphere is as follows: Temperature increases: The green house effect is increased due to the increase in the amount of carbondioxide and the heat trapped on the surface of the earth will not return waway from the earth.

The stratosphere, where the amount of ozone is very thin and through which the harmful solar radiation can enter into the earth is called ozone hole.
