According to the definition of the US Environmental Protection Agency, fine dust, or sometimes referred to as PM - Particulate Matter, is inorganic or organic molecules suspended in the air, and often originates from dust, soil, soot, and mainly from smoke through the burning of organic fuels in industry or transportation.
The size of fine dust particles is very diverse, from particles that can be seen with the naked eye to molecules that are almost invisible. The size of fine dust particles is usually written after the character PM, and is measured in µm (micrometer). Causes respiratory diseases
Long-term exposure to poor air quality can easily cause respiratory diseases such as chronic bronchitis, impaired lung function, asthma, and even lung cancer.- Toxic to other organ systems
In addition to the respiratory system being the most severely affected by fine dust, other organ systems are also affected, such as the circulatory system, nervous system, and reproductive system of humans. Long-term exposure to fine dust can disrupt the body's metabolic pathways, making it susceptible to disease.
- Affects cells and DNA molecules
During exposure to fine dust, the body produces free radicals, which are dangerous to cells and the body's most important molecules such as DNA. If you are exposed to fine dust for a long time, the risk of mutation will increase, making it easier to form cancerous tumors. Impact on the health of infants and young children
Regular exposure of the mother to fine dust can also affect the health of the fetus, and the newborn may experience conditions such as underweight, autism or mental retardation.
