Magnetite Pollution

Why in news?

• Recently, some Geologists have found the presence of Magnetite Pollution on the roadside Dust of Kolkata.
• The frequency of pollutants is higher in areas with heavy vehicular traffic and other polluting sources. The amount of magnetite is proportional to the traffic on a given road.

About Magnetite Pollution:

• Magnetite pollution refers to the presence of a magnetic mineral called Magnetite (Fe3O4) in the environment, as a result of human activities such as mining, steel production and industrial processes.
• Magnetite is an oxide of iron. It is the most magnetic of all the naturally occurring minerals on earth. It is a natural magnet.
• Magnetite contains about 72% metallic iron in it. It is found in Karnataka, Andhra Pradesh, Rajasthan, Tamil Nadu, Goa and Kerala.

Impact:

• Contaminate soil and water:
  • Magnetite particles can settle in the soil and water, contaminating these environments and affecting the growth of plants and the health of aquatic life.
• Affects ecology:
  • Magnetic particles can interfere with the migratory patterns of birds and other animals, affecting their survival and reproduction.
• Damage on buildings and infrastructure:
  • Magnetic particles can cause corrosion of steel structures and other metal objects, leading to damage over time.
• Effect on human health:
  • Inhaling magnetic particles can cause respiratory problems and other health problems, such as lung cancer, cardiovascular disease, and central nervous system damage.
• Damage on electronic equipment:
  • Magnetic pollution can also interfere with the operation of electronic equipment, such as compasses and navigation systems.
