Question

Description of method followed of air pollution

Answer 1

Today we know our world is too small for such practices: sulphur dioxide emitted from factories and power stations has been shown to acidify lakes half a continent away, and acid rain from the same sources has damaged two thirds of all the trees in Europe. The hinterlands around many cities are often shrouded in traffic-produced smog and respiratory illnesses are on the rise across the developed world.

Seen from space, our urban centres are overhung by invisible plumes of pollution. Envisat’s atmospheric instruments can trace the emission of waste chemicals by industry, power generation and traffic, and follow their subsequent movements through the atmosphere.

MIPAS examines the infrared part of the spectrum to detect the signatures of more than 20 trace gases, including such harmful pollutants as hydrocarbons, nitrogen oxides, tropospheric ozone and some CFCs. MIPAS looks either sideways or rearwards into the atmosphere, gathering vertical profiles of pollutants between about five and 150 km. This information is important, because many of these chemicals have the potential to react harmfully with other atmospheric gases, depending on their altitude.

Answer 2

Methods of air pollution:-  

______________________

Introduction : Air pollution is one of the most dangerous types of pollution, nowadays. At the present time there are many sources and methods of air pollution which are mostly caused by the humans.

Further description:

_______________

Methods -

1) The smoke produced from the petroleum operated vehicles.

2) Smoke produced from the combustion of the fuel materials.

3) Different dust particles of different harmful substances which are often produced in the construction sites.

4) Different harmful gas emission from the industrial factories.

5) Production of CFC,methane and other greenhouse gases from the AC, refrigerator etc.

The above mentioned methods are the most major methods of air pollution at the present time,which is ruining our environment.
