Sensors and instruments for measuring airborne concentrations of PM2.5&PM10

The air quality monitoring station analyzes the situation of environmental air pollution based on the monitored air quality data, and studies its harm to environmental air pollution.Air quality monitoring stations can monitor the concentration of these substances to facilitate the scientific prevention and control of environmental air pollution.

At present, the most mentioned environmental air pollution is PM2.5 and PM10, because environmental air pollution is mainly dust pollution, and PM2.5 and PM10 are important components of it, so the timely monitoring, prevention and control of PM2.5 and PM10 is one of the important tasks in the management of air pollution.

Air quality monitoring stations typically monitor and report the levels of PM2.5 and PM10 in the air. PM2.5 and PM10 represent particulate matter (solid and liquid particles suspended in the air). 

PM2.5: PM2.5 refers to particulate matter with a diameter equal to or less than 2.5 micrometers. These particles can be generated by combustion processes (such as vehicle emissions and industrial emissions), dust, pollen, bacteria, etc. Due to their small size, PM2.5 can penetrate deep into the respiratory system and enter the lungs, posing higher risks to human health. Long-term exposure to high concentrations of PM2.5 may lead to respiratory problems, cardiovascular diseases, and other health issues.

PM10: PM10 refers to particulate matter with a diameter equal to or less than 10 micrometers. Similar to PM2.5, PM10 also includes particles emitted from combustion, dust, and other sources. Due to their larger size, PM10 mainly stays in the nose, throat, and upper respiratory system but can still cause respiratory problems.

Monitoring stations typically install sensors and instruments to measure the concentrations of PM2.5 and PM10 in the air. These data are regularly recorded and reported to provide information about the current air quality status. Based on this data, government agencies, environmental organizations, and the public can take necessary measures to improve air quality, such as implementing emission restrictions, strengthening environmental management, or taking personal protective measures.

It's important to note that PM2.5 and PM10 are just two indicators in air quality monitoring. Other parameters such as nitrogen dioxide (NO2), ozone (O3), and sulfur dioxide (SO2) are also commonly monitored. Monitoring these indicators helps to gain a comprehensive understanding of the air quality status and enables corresponding control and protection measures to be implemented.
