PM2.5 and PM10, two types of inhalable particulate matter, affect not only the scenery in front of you

Main components of PM2.5/PM10

Inhalable particulate matter in the air is generally divided into two categories.Inhalable particulate matter PM10 and fine particulate matter PM2.5. Both of which are air pollutants that are more harmful to the human body.  The former refers to the particle size of 10 microns. The following particulate matter.The latter refers to particulate matter with a particle size of less than 2.5 microns.

The components of PM10 and PM2.5 are very complex. Including organic matter, metal elements and their compounds, sulfates and sulfur dioxide. Nitrates and nitrogen oxides, silicates and silicon dioxide, bioaerosols, etc.

PM10 is usually produced in various industrial processes. In addition, in nature, some ultrafine particles and bacteria will stick together to form aerosols. Which is also one of the sources of PM10 in the air.

PM2.5 includes natural products such as soil dust, sea salt, pollen, spores, bacteria, and volcanic ash. As well as smoke and dust generated in industrial projects such as power generation, metallurgy, oil refining. Chemistry, and textiles, and droplets left due to insufficient fuel combustion. Indoors, second-hand smoke and cooking with hot oil can also form a large number of PM2.5 particles.

After getting angry in winter, in addition to ensuring the ventilation of the living environment and drinking more water. You should also consume more foods that can clear heat and detoxify, such as bitter gourd, white radish and spinach.

The harm of PM2.5/PM10 to human body

Some of these substances can cause human poisoning and radioactive contamination, some can cause symptoms of acute bronchitis, pulmonary edema and dyspnea, some can cause damage to the heart, liver and stomach and even lung fibrosis, and some can cause allergies rhinitis and pulmonary dysfunction.

 

In addition to the above easily observed phenomena, prolonged exposure to an environment with high levels of PM10 and PM2.5 increases the risk of developing lung cancer.

In addition, if the air contains higher concentrations of PM10 and PM2.5. It will also lead to reduced atmospheric visibility, the whole sky looks gray. And at the same time, the buildings in this area are also more prone to erosion. Those reinforced concrete structures. Or modern buildings with a large area of ​​glass exterior walls are not bad. Because the corrosion resistance of these buildings is relatively strong, but those ancient buildings and historical buildings. Especially those with wooden structures, are a little too much to bear. The erosion effect of PM2.5 on these buildings is no worse than that of acid rain. And the erosion process is more persistent and pervasive. Acid rain will only damage the eaves and outer walls of the building. But PM10 and PM2.5 will connect the interior of the building. Space is also affected.

 

After PM10 is inhaled by the human body, it will accumulate in the human respiratory system, causing various diseases and causing great harm.

The particles of PM2.5 are smaller, so under the same mass, the surface area is larger, the activity is stronger, and it is easier to carry toxic and harmful substances. The time spent in the atmosphere is longer than that of PM10, and the diffusion range is further. .5 is more harmful than PM10.

Recommended prevention and treatment

How to monitor the content of PM10 and PM2.5 in the air is one of the important contents of air management.

This air quality sensor has a built-in high-quality laser probe, which can detect particles with a minimum particle size larger than 0.3 microns, and the minimum measurable concentration can reach 0.1 micrograms/m³. It has high measurement accuracy, low power consumption during operation, and a wider measurement range. It can effectively monitor the content of PM2.5 and PM10 in the air, and also has the function of monitoring air VOC, carbon dioxide and temperature and humidity.

The shell part is made of high-density material, which is wear-resistant and anti-dropping. At the same time, there are multiple vents on both sides of the body, which has excellent heat dissipation effect. With the ventilation fan, the speed of the air in the external space flowing to the probe is accelerated, and the measurement process is time-consuming.

Weihai JXCT was established based on idea of “Born for IoT”. It is aiming at creating the most comprehensive industrial IoT solutions for   customers from home and aborad.

Weihai Jingxun Changtong Electronic Technology Co., Ltd was established in November 2015, located in Weihai, Shandong, China. It is a national high-tech enterprise, with more than 400 stuff, 3000 square meter factory and independent technology R&D center in Jinan city. As a fast-growing industrial IoT enterprise, it integrates R & D, production, and marketing together.

Its main products include sensor and transmission equipment required for agricultural environmental monitoring, industrial environmental  Monitoring, atmospheric environmental monitoring, smart city and industrial process monitoring. It also provide SaaS cloud platform-JX Cloud as the core integrated industrial IoT solution.
