How to monitor the content of PM10 and PM2.5 in the air.
It is one of the important contents of air governance work. The air quality monitoring stations is an air quality sensor. Built-in high-quality laser probe. but Generally speaking, The lowest detectable particle size is greater than 0.3 microns. The minimum measurable concentration can reach 0.1 microgram/m³. The measurement accuracy is high. Low power consumption during operation. The measurement range is wider. It can effectively monitor the content of PM2.5 and PM10 in the air. It also monitors air VOC. The function of carbon dioxide and temperature and humidity.
The shell part adopts high-density material shell. Wear-resistant and anti-drop. At the same time, leave multiple vents on both sides of the body. Excellent heat dissipation effect. With bleed air fan. Speed up the air flow from the outside space to the probe. The measurement process takes less time.
The main components of PM2.5/PM10
Inhalable particulate matter in the air. Generally speaking, it is divided into two categories. It can inhale particulate matter PM10 and fine particulate matter PM2.5. Both categories are more harmful to the human body. Air pollutants. The former refers to particles with a particle size of less than 10 microns. The latter refers to particles with a particle size of 2.5 microns or less.
The components of PM10 and PM2.5 are very complex. Including organic matter. Metal elements and their compounds. air quality monitoring stations. Sulfate and sulfur dioxide. Nitrate and nitrogen oxides. Silicate and silicon dioxide. Biological aerosols, etc.
PM10 is usually produced in various industrial processes. in addition. in nature. Some ultrafine particles and bacteria will stick together into clusters. Form an aerosol. This is also one of the sources of PM10 in the air.
PM2.5 includes soil dust. sea salt. pollen. spore. germ. These natural products of volcanic ash. There is also power generation. metallurgy. Oil refining. Chemical. The smoke and dust produced in textiles and other industrial projects and the droplets left behind due to insufficient fuel combustion. And indoors. Second-hand smoke and hot oil for cooking. A large number of PM2.5 particles will also be formed.
The harm of PM2.5/PM10 to the human body
Some of these substances can cause it. The human body is poisoned and contaminated by radioactivity. Some can cause acute bronchitis. Symptoms of pulmonary edema and difficulty breathing. Some cause the heart. Damage to the liver and stomach and even fibrosis of the lungs. Others can cause allergic rhinitis and lung dysfunction.
