Causes
Disease-causing agents such as bacteria,
viruses, protozoa and parasitic worms that
enter sewage systems and untreated waste.
Wastes that can be decomposed by
oxygen-requiring bacteria.
Water-soluble inorganic pollutants, suchas acids, salts and
toxic metals.

CausesThe release of carbon dioxide
- used in various industries
- deforestation
- volcanic eruption ( 40% of CO2)
The combustion of fuels in automobiles, jetplanes, etc
The release of carbon monoxide
- major pollutant
- due to any fuel burning
appliance

Solutions
Change in design and operation of machines,vibration control, by
using sound absorbing
materials.
Reduced by prescribing noise limits forvehicular traffic and
planning industrial
establishments, amusement areas, residential
colonies and hospitals .

Solutions
Locate the building as far as possible fromnoise source.
Trees like ashok, neem, coconut can be
planted to provide some absorption of sound. Laws should be made
for controlling noise
hazards at city level.
People can be educated through radio, TV,street play about noise
pollution.
