Ways of controlling Air pollution

People are making many attempts worldwide on a personal, industrial and governmental level to curb and diversify the intensity at which Air Pollution is caused. It is very necessary to regain the balance of the proportion of gases that are traced in the atmosphere to its rightful quantity or it can create havoc in the whole climatic and biosphere system. This will directly put an end to Global Warming. There have been a series of innovations and experiments which are aimed at developing alternate and unconventional options thus leading to decrease the levels of pollutants prevailing in the atmosphere.

We can enumerate few of the effective methods that can be helpful in controlling and preventing the Air Pollution:
  1. Source Correction Method
  2. Pollution Control Equipment
  3. Diffusion of Pollutants in Air
  4. Vegetation
  5. Zoning
  1. Source Correction Method
    Industries cause a huge amount of pollution and emit a large variety of air pollutants in the atmosphere on a daily basis. The formation of pollutants can be curbed or minimized if it is handled tactfully in the source itself. There should be a detailed and careful investigation during the early stages of the design and development in Industrial equipment. Only those methods should be used which have the minimum potential to cause air pollution. Some of the methods that can be included in this process are substitution of raw material with better alternatives, process modification & usage of those methods which are proven to less harmful and modification and maintenance of the existing equipments.
  2. Pollution Control Equipment
    These equipments can be either control devices for particulate contaminants or gaseous contaminants. It is not always feasible to control pollution at the source by preventing the emissions of pollutants. It is during these times that it is necessary to set up devices which will control pollution by removing the gaseous pollutants from the gas stream itself. The effect and presence of these pollutants are highly concentrated at the source and as we move away from the generating place they get diluted with diffusion in to the atmosphere. Gravitational Settling Chambers, Cyclone Separator, Fabric Filters, Electrostatic Precipitators and Wet Scrubbers are few of the equipments that are being commonly used to deal with the problem.
  3. Diffusion of Pollutants in Air
    By diluting the contaminants in the atmosphere is another way to deal with air pollution.When the amount of pollutants let out in the atmosphere is in small quantity then the pollutants are easily diluted. When there is a huge amount beyond the limited capacity of pollutants that is let out then it causes a problem. The extent of dilution of pollutants depends upon the atmospheric temperatures, speed and also the direction of the wind flow. The dilution only dilutes the contaminants to a level which reduces their harmful effects to a certain extent. But as the distance increases from the source these contaminants come down some way or the other.
  4. Vegetation
    Plants are one of the most important carbon sinks that prevail in the biosphere as they use Carbon Dioxide and release oxygen in the process of photosynthesis and thus purifying the air. The plant species of Pinus, Quercus, Pyrus, Juniperus and Vitis are helpful in depolluting the air by metabolizing the nitrogen oxides. There should be planting of huge number of plants where there is a high risk of pollution to somewhat mitigate its effects.
  5. Zoning
    It a type of activity which can be undertaken by newly developed townships and the new cities and preferably in the development stage. There should be proper understanding of the land area and thus dividing the area in such a way which will be justifying the location of more polluting sectors away from the main residency or the main city area.The heavy industries should be further away and located far off from each other too. New industries if coming up should be placed away from the large cities also keeping a check of population migration taking place in these cities decided as per regional planning.

Air pollution is an issue which is being felt at every level and is consequently harming all sections of human as well as flora and fauna. Every activity in our day to day life and the minor decisions we make can have a huge consequential effect so we need to choose and judge accordingly with legitimate understanding of the aggravating situations.
