We know that air pollution levels are higher in buildings in rural and highly industrial areas and lower in urban areas.
Although it may smell and look clean, the fact is that even if you had a bionic eye, many of the pollutants in the air would be detected in your eyes. Even with a pair of bionic eyes, one cannot look at the pollen grains of ordinary plants without a very good sense of smell.
A particle in the air is measured in micrometers , with one micrometer being about the size of a human hair or about 1 / 10 millimeter in diameter.
Sometimes micrometers are also called microns. microns and micrometers are used interchangeably as the two most common measurements of the size of a human body and also as measurements of physical activity.
Given the size of the particles, which are micrometer in size, the waste mass of dust mites is about 5 micrometers, while a strand of hair is between 100 and 150 micrometers wide.
The smallest particles that can be seen with the eyes are those larger than 50 micrometers, like dust collected from furniture.
Particles in the air are far too small to be seen by our eyes, but they are known to trigger allergic reactions.
For example, pollen particles known to cause hay fever – the most common cause of allergic reactions – are only 3 to 70 micrometres in size. It is also believed that the body’s immune system, especially the brain and nervous system, is more sensitive to the effects of particulate matter if exposed to it regularly.
These include, but are not limited to, certain types of pesticides and herbicides, as well as certain types of metals such as lead, mercury, arsenic, lead and mercury.
These tiny particles tend to hang in the air for longer, increasing the likelihood of being inhaled deep into the body. Once inhaled, they can enter the airways such as the nose and lungs through the bloodstream, causing breathing problems.
These particles are potential irritants and can infect free-riders with bacteria that can cause inflammation, skin inflammation and even cancer if you are prone to certain diseases, have pre-existing conditions or have chronic diseases such as diabetes, heart disease, cancer.
As a result, it is often out of sight when it comes to air quality, especially in cities with high levels of air pollution.
What you don’t see today can be a kilometer away from you or even as far away as the next street.
