Every day I commute to the road, the exhaust of the car makes me feel very uncomfortable. Every time I walk behind the smoker, I feel the suffocation to speed up the pace, the hot air of the subway, the smell of the human body, the perfume smell, the fumes, do you realize that these air pollution is everywhere?
The main pollutants in the air including below 4 parts:
- particulate matter from fuel combustion;
- Nitrogen dioxide produced by road traffic or indoor gas stoves;
- Burning sulfur dioxide from fossil fuels;
- Ground-level ozone produced by the reaction of sunlight with pollutants in vehicle exhaust.
The pollutants that affect people the most are particulate matter, often abbreviated as PM and used as a measure of air pollution. Although particles with a diameter of 10 microns or less (≤ PM10) can penetrate and penetrate deep into the lungs, those that are more detrimental to health are those with a diameter of 2.5 microns or less (≤ PM2.5). These particles are very small, only one-60th of the diameter of a human hair.
PM2.5 can enter the blood system through the lung barrier.
Long-term exposure to these particulates may increase the risk of cardiovascular and respiratory diseases, as well as lung cancer.
For PM2.5, the highest level of safety set by the WHO Air Quality Guidelines is an average annual concentration of 10 μg/m3 or less. To encourage cities to reduce air pollution, even if they fail to achieve the desired level of safety, WHO has set three transition goals for them: 15 μg/m3 (transition target 3); 25 μg/m3 (transition) Target 2); 35 μg/m3 (transition target 1). Many cities currently exceed the highest level of transition goal 1.
Ozone is a major cause of asthma (or worsening of the condition), and nitrogen dioxide and sulfur dioxide can also cause asthma, bronchial symptoms, lung inflammation, and decreased lung function.
However, the current photocatalytic single air pollution control technology in the market has been unable to meet the market demand. According to this demand, SKYISH has developed a composite biological enzyme treatment technology and derived a series of products based on this technology.
