Industrial pollution is the introduction of
waste material from factories, mining and
construction operations into the environment.
It constitutes mainly land pollution, air
pollution and water pollution.
Types of Industrial Pollution
• Air Pollution
• Water Pollution
• Soil Pollution
Impacts on Air Quality due to Industries
• Carbon Emissions
• Global Warming
• Acid Rain due to emission of large amounts of
gases such as carbon dioxide, sulphur and
nitrogen, among others.
Global Emissions by Source
Emissions by Country
Water Pollution due to Industries
• Industrial water pollution is caused by the
discharge of harmful chemicals and
compounds into water, which makes it
unsuitable for drinking and other purposes.
Effects of Industrial Water Pollution
✧ Change the pH and colour of water
✧ Alter the nutrient content
✧ Change water temperature (thermal pollution)
✧ Increase the amount of minerals and salts in
✧ Increase the murkiness (dark colour) of water
Land Pollution due to Industries
• Large quantity of solid wastes like unused and rejected
chemicals unwanted industrial wastes generated during
manufacturing processes are dumped over on the surface of
soil by almost all industries with difference in the degree.
• All these solid materials dumped on surface of soils are bound
to change the chemical and physical nature of soil.
• It also results in large quantity of pollutants leaching to
pollute underground water.
Status of Soil Contamination in India
• Govil et al (2001) significant contamination, showing two to
three times higher levels of toxic elements than normal
around the Patancheru industrial development area of Andhra
Pradesh, just north of Hyderabad city.
• Singh et al. (2002) studied Ganga river plain for heavy metal
contamination, stream sediments from Lucknow, Kanpur,
Delhi and Agra were classified as highly polluted to dangerous
• Krishna and Govil (2004) their data revealed that the soil in
the Pali Industrial area in the western state of Rajasthan is
significantly contaminated with high concentrations of heavy
elements like Pb, Cr, Cu, Zn, Sr and V.

Steps to curb Industrial Pollution and in
turn reduce its Impact on the Environment
1. Proper and Strict enactment of Policies to
2. Terminate Unplanned Industrial Growth
3. Cease use of Outdated Technologies
4. Regulate large number of Small Scale
5. Impede Inefficient Waste Disposal
