It is noted that suspended particles of PM2.5 in atmospheric air are particles that pass through the respiratory tract. They enter the alveoli and pulmonary capillaries, where gas exchange takes place, and pass through the systemic blood stream. Entering various organs, it has a direct local effect on tissue cells.
According to experts, small dispersed particles have the ability to penetrate cell membranes. In addition, there is a risk of their chronic accumulation in organs and tissues.
Long-term exposure to high concentrations of PM10 and PM2 in atmospheric air has an inflammatory, carcinogenic, teratogenic, cytotoxic effect, contributes to the development of allergic pathology and affects human life expectancy.
In order to protect against these particles, experts recommend cleaning the floors and shelves of rooms or buildings, the items and objects inside them with a damp cloth. He recommends hanging wet towels inside the house or building, reminding that placing containers with water around them will help reduce the dust level.
It is also necessary to implement the following recommendations:
• keep the windows closed, especially at night and early in the morning, tightly closing the doors and windows;
• drink more water;
• restriction of movement in the open air;
• frequent showering, especially after entering the house from outside (this process eases breathing);
• rinsing the mouth and nose with a saline solution;
• eye wash (especially for contact lens wearers) is recommended.
The Committee also stressed the need for people with respiratory diseases to use medical masks and change them every 2 hours.
