INTRODUCTIONINTRODUCTION

Pollution is the introduction of contaminants into an environment that causes harm to human health, other living organisms & the environment.

Undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities.

TYPES OF POLLUTIONSTYPES OF POLLUTIONS

1. Air pollution

2. Water pollution

3. Soil contamination

4. Radio active contamination

SOURCES AND EFFECTS OF SOURCES AND EFFECTS OF POLLUTIONSPOLLUTIONS

SOURCES :

Motor vehicle . Chemical plants and refinery. Sometimes natural disaster

EFFECTS :

Adverse air quality can kill many organism including humans. Ozone depletion. Sulfur dioxide and oxides of nitrogen can cause acid rain.Water pollution causes about 14000 deaths/day due to contamination of drinking water.

PLASMA TECHNOLOGYPLASMA TECHNOLOGY

Plasma- The 4th state of matter :

• Plasma are electrically conducting gases.

• Operates at about atmospheric pressure.

Emerging applications of plasma technology.

EMERGING APPLICATION OF PLASMA EMERGING APPLICATION OF PLASMA TECHNOLOGYTECHNOLOGY

Environmental Protections :

• Destruction of waste.• Reduction of pollution from diesel trucks and buses.

Energy Savings :

• High efficiency, clean gasoline engines

Other application: • Plasma cutting.

CONCLUSIONCONCLUSION

Plasma furnace technology is beginning to be used commercially to destroy waste and produce hydrogen and other useful products.  Use of plasma hydrogen technology to treat diesel exhaust shows promise for meeting strict 2010 EPA requirements.  High efficiency gasoline engines using plasma technology could Significantly reduce CO2 greenhouse gases and dependence on Foreign oil.
