What is Dust Know everything about Dust Advantages Disadvantages of Dust
Every solid substance is composed of very small particles.
When these small particles of matter are scattered, they become dust particles.

If we break a stone into small pieces, it will turn into small particles of dust.

There are different ways by which dust gets created.

Humans naturally lose things like dead skin and hair without knowing it, which often turns into dust

The percentage of the dust in our home that is actually dead skin cells is approximately 75% to 90%.

Dust consists of particles in the atmosphere that comes from various sources such as soil dust lifted by wind (an Aeolian process), volcanic eruptions, and pollution.

Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles and many other materials which may be found in the local environment.

According to The Boston Globe, 30,000-40,000 skin cells fall off you per minute, and on average 8.8 pounds of dead skin, cells fall off our body per year.

United States Federal law requires that construction sites obtain permits to conduct earth moving, and include plans to control dust emissions.

Control measures include such simple practices as spraying construction and demolition sites with water, and preventing the tracking of dust onto adjacent roads.

US federal laws require dust control on sources such as vacant lots, unpaved parking lots, and unpaved roads.

Dust control is the suppression of solid particles with diameters less than 500 micrometers

Dust storms are caused by forceful winds passing over loose particles of dust. Dust has been lifted to about 3.8 miles (6.1 km) above the earth by a dust storm.

Disadvantages of dust 

According to the Environmental Protection Agency, "Indoor air can be 2 to 5 times more polluted than outdoor air."

Airborne pollution contributes to minor annoyances such as itchy eyes, sneezing, dusty furniture and headaches

It can also be a major contributing factor to severe allergies, life-threatening asthma

Majority people suffer from dust allergy.

Coal dust is responsible for the lung disease known as pneumoconiosis, including black lung disease that occurs among coal miners.

Dust mites feed on the organic particles in dust and can cause heath issues such as asthma and allergies.

Dust mites are not visible to eyes and can be only seen with the help of a microscope.

Advantages Benefits of Dust –

The water vapor in the clouds condenses on dust particles in the form, of water drops. These drops fall on to the earth as rains.

The dust particles present in the atmosphere scatter sunrays in all directions. Due to this scattering, there is not complete darkness for one to two hours even after the sunset.

The appearance of red color at the sunrise and the sunset is due to dust particles and water vapor.

The beautiful rays of the sun seen in the twilight are also due to these dust particles

We cannot eliminate dust but we can just keep dust away from our homes.
by cleaning home regularly.

If you got extra money, you can buy Air Purifiers but check the manual of Air Purifier what it cleans exactly.

I am surprised to read the fact that home dust contains 75-90% dead skin cells and per person yearly accumulation is 8 pounds. I am trying to figure our where is all this dead skin dust hiding in home?

I have witnessed several magical colorful twilight glows and amazed to read that they are caused by dust particles.

In USA winter time indoor air is worst and unhealthy.

sm, thanks for this informative post.
