WHAT IS POLLUTION ?
We all know the word pollution but what it is and how harmful or pollution comes from. Many of us do not know.When we hear the name pollution we walk backwards but once again we try to understand whether we are living with pollution day and night or we are carrying pollution or we are creating this pollution.Can't we prevent pollution? Can't we survive pollution? We can create and destroy everything possible. But before that you need to know what kind of pollution and what diseases it causes in humans.
NOISE POLLUTION
Noise pollution refers to undesirable levels of noises caused by human activity that disrupt the standard of living in the affective area.Nose pollution can come from.
1. Traffic,
2. Airports,
3. Railroads,
4. Manufacturing plant,
5. Constraction or demolition,
6. Concerts.
Some noise pollution may be temporary while other sources are more permanent. Effects may include hearing loss, wildlife disturbances, and a general degradation of lifestyle.
RADIOACTIVE POLLUTION
Radioactive pollution is rare but extremely detrimental, and even deadly, when it occurs. Because of 'its intensity and the difficulty of reversing damage, there are strict government regulations control radioactive pollution.
Sources of radioactive contamination include:
1. Nuclear power plant accidents or leakage.
2. Improper nuclear waste disposal
3. Uranium mining operations.
Radiation pollution can cause birth defects, cancer, sterilization, and other health problems for human and wildlife populations. It can also sterilize the soil and contribute to water and air pollution.
THERMAL POLLUTION
Thermal pollution is excess heat that creates undesirable effects over long periods of time. The earth has a natural thermal cycle, but excessive temperature increases can be considered a rare type of pollution with long tem effects. Many types of thermal pollution are confined to areas near their source, but multiple sources can have wider impacts over a greater geographie area.
Thermal pollution may be caused by,
1. Power plants,
2. Urban sprawl,
3. Air pollution particulates that trap heat,
4. Deforestation,
5. Loss of temperature moderating water supplies,
As temperatures inerease, mild climatic changes may be observed, and wildlife populations may be unable to revn from swift changes.
LIGHT POLLUTION
Light pollution is the over illumination of an area that is considered obtrusive. Sources include,
1. Large cities,
2. Billboards and advertising,
3. Night time sporting events and other night time entertainment.
Light pollution makes it impossible to see stars, therefore interfering with astronomical observation and personal enjoyment If it is near residential areas, light pollution can also degrade the quality of life for residents.
