Types of pollution
Air pollutionWater pollutionSoil pollutionRadiationNoise pollution
AIR POLLUTION
• Air pollution means degradation of the air quality harmfully affecting the living organisms as well as certain objects.
Particulate pollution
Gaseous pollution
Sources of pollution
Natural sources•volcanoes•Storms Man-Made sources•automobiles•industries
Vehicular air pollution
The exhausts given out contain three main gaseous pollutants:CO2,SO2 and CO.
Industrial air pollution
The smoke released by the factory chimneys into the air contains lot of particulate pollutants
Burning garbage
The smoke given out on burning garbage releases CO2 and some other harmful gases which adds to the particulate air pollution.
Brick kilns
Brick kilns are fire-heated enclosures for making construction bricks. Lot of smoke and heat given out are pollutants.
Water pollution
• Any change in the water quality which makes it unsuitable for use by humans and by other living organisms.
SOURCES OF WATER POLLUTION
Household detergents Sewage
Industrial wastes
Oil spills
Thermal pollution
HOUSEHOLD DETERGENTS
SEWAGE
•
INDUSTRIAL WASTE
OIL SPILLS
THERMAL POLLUTION
• Hot waste water released into nearby streams by industries cause thermal pollution affecting living organism.
SOIL POLLUTION
• Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment.
SOURCES
SOURCESIndustrial waste
Urban commercial and domestic waste
Chemical fertilizers
Biomedical waste
pesticides
Radiation
• Radiation is a form of energy consisting high energy particles. It is extensively used in medical fields and generating electricity.
Chernobyl nuclear disaster
Noise pollution
• Noise is defined as any disturbing sound.
Effects of noise pollution
• Interferes in communication• Interrupts concentration of thought• Lowers efficiency• Disturbs sleeps• Irritability• Damage ear drum• Lead to deafness• Bird life gets disturbed
OTHER EFFECTS OF POLLUTION
• Acid rainAcid rain is a rain or any other form of precipitation that is unusually acidic.
• Greenhouse effect and global warmingGreenhouse are small houses specially
constructed to grow plants.Global warming is continuing rise in the average
temperature of Earth's climate system.
• Ozone layer depletion
