Magnetic Pollution

• Magnetite pollution has recently been discovered by some geologists in Kolkata's roadside dust.
• In regions with considerable vehicular traffic and other polluting sources, pollutants occur more frequently. The quantity of magnetite varies with the volume of traffic on a particular road.
• The method exposes the existence of several magnetic components, and by linking them to particular pollution sources, the researchers were able to determine which sources predominate in which locations.
• Their research is in the field of environmental magnetism, which employs magnetism to illustrate the effects of pollution, climatic change, and environmental footprints on magnetic minerals found in environmental samples like soil, dust, and sediments.

Environmental Magnetism:

• The study of magnetism in relation to how the environment influences magnetic minerals, including how the climate, the movement of sediment, pollution, and other factors.

• It employs methods from magnetic mineralogy and rock magnetism.
• In fields including paleoclimate, paleoceanography, investigations of the origin of sediments, pollution, and archaeology, the magnetic properties of minerals are employed as proxies for environmental change.
• Magnetic measures have a number of benefits, but their main benefits are that magnetic minerals are nearly universal and that magnetic measurements are rapid and non-invasive.

Magnetic Pollution: What Is It?

• Magnetite pollution is the term used to describe the occurrence of the magnetic mineral magnetite (Fe3O4) in the environment as a result of a variety of human activities, including mining, the manufacture of steel, and industrial processes.

• Magnetite is an oxide of iron. Of all the naturally occurring minerals on earth, it has the strongest magnetic properties. It has a built-in magnet.
• About 72% of magnetite is made up of metallic iron. It can be found in Kerala, Goa, Rajasthan, Tamil Nadu, Andhra Pradesh, and Karnataka.
• Magnetic particles can disrupt the migratory habits of birds and other animals, which can have an impact on their survival and procreation.
• Magnetite particles have a tendency to settle in soil and water, polluting these ecosystems and impairing plant development and aquatic life health.
• Human Health: Exposure to magnetic particles can result in respiratory issues as well as other health issues such lung cancer, cardiovascular illness, and harm to the central nervous system.
• Damage to buildings and infrastructure: Magnetic particles can induce corrosion in steel buildings and other metal items, which over time can result in damage.
• Damage to Electronic Equipment: Magnetic pollution can also prevent electronic devices like compasses and navigation systems from working properly.

Therefore proper research and measures to control and prevent from this pollution needed to be mooted.
