PM 2.5 is an air pollutant that includes both solid microparticulate pollutants and tiny droplets of liquids. Both are approximately 10 nm to 2.5 microns in size. There are also other names of PM 2.5, for instance, FSP ( fine suspended particulates), fine particles, fine particulate matter, and fine dust.

Unlike larger particulate pollutants, PM 2.5 easily penetrates biological barriers and presents a significant risk to the body. They exist in both the forest and the sea, yet it is in the city where they pose the greatest threat. To begin with, they are typically more prevalent in urban areas, and furthermore, the chemical makeup of fine particles in the city presents higher risks than that found in natural environments.

The mass concentration of PM 2.5 is a key parameter for assessing air quality and its threat to human health. According to the standards of the World Health Organization (WHO), the average annual level of PM 2.5 should not exceed 10 mgr/m3, and the average daily level should not exceed 25 mgr/m3.

For instance, in modern China, this abbreviation is known by almost every resident. These particulate pollutants are also widely recognized in other parts of the world. This stems from a basic truth: PM 2.5 is dangerous. This problem becomes more and more obvious. PM 2.5 particulates reduce life expectancy by an average of 8.6 months. Only 3% of deaths are connected with PM 2.5 resulting in cardiovascular and respiratory diseases and 5% of deaths – lung cancer.

There are many different particulates in urban air: small and large, light and heavy. Only large particulate pollutants eventually settle on the ground, whereas light PM2.5 hardly ever builds up.

There is always PM 2.5 in the air of a large city. People constantly inhale them. The only question is about the typical daily intake of PM 2.5 that enters the body. If the body has time to clear and recover, the probability of the above health problems will be significantly reduced. It’s a different situation if more harmful particles enter the body daily than those that are expelled. Then pollutants will accumulate in the body. The symptoms of “poisoning” by PM 2.5 will show up unnoticed. The body slowly wears out from the dirty air, but there is no sharp deterioration in health. The negative effect is not instantaneous but delayed.

However, there are air treatment systems that allow for dealing with this problem. The most effective way is the use of a wet scrubber. If you would like to make your contribution to improving air quality to provide air pollution control, Redwood Technology offers a cutting-edge wet scrubbers that is Multi-Vortex scrubber. Multi-Vortex wet air scrubber could apply water contaminated with dust, sand, and even small rocks to capture particulate pollutants, different types of dust, and some gases from the air. 

This type of scrubber is an ideal solution for ore and coal mining. Thus, it can be used in different mining, combustion, and chemical processes to capture gases. Also, in some cases, the unique Multi-Vortex scrubber design allows utilizing cheaper reagents to capture the pollutant gas with more efficiency than a standard wet scrubber.
