Question

Rubber particles and dust raised by running motor vehicles are examples of _______ pollutants.

Answer 1

Fine solid matter particles make up dust. It is made of particles in the atmosphere that arise from a variety of sources, including wind-lifted soil (aeolian process), volcanic eruptions, and pollutants. About half of the dust in our houses is made up of dead skin cells. Small amounts of plant pollen, human hairs, animal fur, textile fibres, paper fibres, minerals from outside soil, burned meteorite fragments, and other things found in the surrounding environment make up the rest, as well as in workplaces and other human settings.

Complete Step By Step Answer:
A pollutant is a material or energy that is released into the environment and has unfavourable consequences or reduces the utility of a resource. By altering the development rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values, a pollutant can inflict long- or short-term damage. Some contaminants are biodegradable, which means they won't last long in the environment. However, some pollutants' degradation products, such as DDE and DDD generated by DDT breakdown, are harmful in and of themselves. Particulate pollution occurs when particles suspended in a medium pollute the environment. Atmospheric particulate matter, marine debris, and space debris are the three main types. Particulate pollution can originate from both natural and human causes. A particulate pollutant is a mixture of tiny or microscopic liquid and solid particles suspended in the air. Particulate matter is produced by a variety of human activities, including vehicle emissions, smoke particles, dust particles, and industrial waste. There are two forms of particulate matter in the air: viable particles and non-viable particles. Particulate pollution includes rubber particles and dust created by moving automobiles.

Note:
The diameter of dust particles is more than 1 micrometre (m). Grinding, crushing, and attribution of solid things produce dust particle matter. The discharge of sawdust during construction, the release of sand particles during sandblasting, the pulverisation of coal, the release of fly ash and cement from industries, and dust storms are all examples of this sort of particulate emission.
