Pollution
Environmental pollution refers to the degradation of environmental
quality at the local level by the actions of humans. Environmental environment
at local, regional and world levels by human works and natural processes.
Degradation occurs. Industrial development, urbanization, nuclear energy etc.
Level is elevated but its deadly consequences Consequently, environmental
balance has stagnated.
Types of pollution
Humans have polluted the environment directly or indirectly by spreading
many destructive elements. Environmental pollution can be divided as follows.
1. Sound Pollution
2. Water Pollution
3. Soil Pollution
4. Nuclear pollution
5. Thermal Pollution
6. Air Pollution
7. Urban pollution
1. Noise pollution
When the sound exceeds one limit, then it is human and Other organisms
become fatal for animals, then they are called noise pollution. The intensity
of the sound is measured in decibels or bell. For a normal person, hearing
sound of 50 decibility intensities is appropriate and normal. From 80 decibels
The sound of more intensity, is called noise.
Due to noise pollution
The causes of noise pollution can be divided into two parts.
Natural causes
Human reason
2. Water Pollution
Water pollution is only to meet any kind of undesirable gaseous, liquid
or solid substances in water.
Due to water pollution
Water pollution is caused by two reasons.
Natural 2. Anthropogenic Natural Factors
3. Soil Pollution
When the top layer of land is depleted due to human or nature in the
quality of the soil, then it is called soil pollution.
4. Nuclear pollution
The radiation from the diodeactive substance is called 'radioactive pollution'. Dioactive substances automatically emit radiation; Such as uranium,
thorium, plutonium etc.
5. Thermal pollution
Unwanted increase in temperature of atmospheric factors is called
thermal pollution.
Thermal pollution can be divided into two parts. 1. Water Thermal
Pollution 2. Atmospheric thermal pollution
6. air pollution
Uninterrupted elements of which air is polluted. They are called air
pollutants and pollutants generated by them are called air pollution.
