Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn’t need to be tangible. We can see pollution like;
Noise pollution has harmful effects on both our body and mind. The safe intensity level of sound, as prescribed by World Health Organization (WHO) is 45 dB.
One of the best ways of reducing noise pollution is through making green belt around the residential areas, around airport and on the sides of the road where the vehicles and trains run. Also, following steps should be followed to prevent noise pollution to the highest extent.
a. Raising public awareness about the effect of noise pollution, b. Distributing up-to-date information regarding noise pollution, c. Strengthening laws and governmental efforts to control noise pollution, d. Establishing networks among environmental professionals, governmental and all other activist groups working on noise pollution issues, e. Helping and protecting activists working against noise pollution.
Controls: (1) Control at Receiver’s End (2) Suppression of Noise at Source (3) Acoustic Zoning (4) Sound Insulation at Construction Stages (5) Planting of Trees (6) Legislative Measures.
It is an undesirable change in the physical ,chemical or biological characteristics of air.They are the substances which pollute the air.Some of the common pollutants are dust,soot,ash,carbon monoxide,excess of carbon dioxide, sulphur dioxide,oxides of nitrogen,hydrocarbons,chlorofluorocarbons(CFC),lead compounds,asbestos dust,cement dust, pollen and radioactive rays.
Air pollution affects respiratory system causing breathing difficulties and diseases such as bronchitis,asthma,lung cancer,tuberculosis and pneumonia.
Different techniques are used for controlling air pollution caused by ‘gaseous pollutants’ and that caused by ‘particulate pollutants’.The air pollution caused by gaseous pollutants like hydrocarbons,sulphur dioxide,ammonia,carbon monoxide,etc can be controlled by using three different methods-Combustion,Absorption and Adsorption.
When pollutants (particles, chemicals or substances that make water contaminated) are discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Pollutants get into water mainly by human causes or factors.
Nutrient Pollution(Fertilizers, Sewage), Surface water pollution(Rivers, Lakes, Lagoons, Oceans), Oxygen Depletion(Too much biodegradable matter in the water can cause more Microbial growth and Oxygen usage), Ground Water Pollution (Fertilizers, Chemicals, Pesticides can go with rain water deep down to the water), Microbiological (Bacteria, Virus and Protozoa in water), Suspended matter (Substances, Heavy Metals, particles and chemicals), Chemical water pollution (Agricultural waste water, Industrial waster water), Oil Spillage (Oil spills usually have only a localized effect on wildlife but can spread for miles, and destroy aqua life).
Dealing with water pollution is something that everyone (including governments and local councils) needs to get involved with. Here are a few things you can do to help.
Land pollution, in other words, means degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities. We have all heard the R’s: reduce, reuse, recycle. Following methods can prevent and control the land pollution.
1. Reduce the use of harmful products to the environment (Petrol, Diesel, Fertilizers, Pesticides), 2. Reduce the amount of Plastic you use (Use bio-degradable, Jute), 3.Reduce your garbage amount (Maintain properly the sewage lines, septic tanks, oil tanks and do not burn trash like Tyres and plastics in open air), 4.Reduce Paper use (Use digital paper more), 5.Plant more trees of native species like Neem, Pipal etc.,
This is the form of pollution most people have forgotten: light pollution. And while undark skies may not rank in importance alongside the chemical trash we routinely dump into the atmosphere, the continuous, unblinking glare of modern life is not without its impact on wildlife, dwindling energy resources and human health.Light pollution is so widespread, so universal, so common to urban life.
Ways to reduce light pollution: Start with the light switch turning off. Terminate the outdoor sodium vapour lamps, Consider replacing outdoor lights with intelligently designed, low-glare fixtures, Place motion sensors on essential outdoor lamps, Replace conventional high-energy bulbs with efficient outdoor CFLs and LED floodlights.
Now, Enjoy the Darkness.You don’t need a telescope to see the major constellations, bright nebulas, open clusters, many of the planets, comets, meteors and dozens of man-made satellites and spacecraft.
So, take a oath in New Year to help control pollution from your part.
