[ Focus on Chemical Machinery and Equipment Network ] Atmospheric pollution is caused by human activities or natural processes that cause certain substances to enter the atmosphere, showing sufficient concentration for sufficient time, and thus endangering the comfort, health and welfare of the human body or the environment.

In recent years, the national air quality has continued to improve, and there has been a steady and improving trend
.
In 2020, a total of 345 days of severe pollution occurred in 337 cities across the country, 107 days less than in 2019; 1,152 days of severe pollution, 514 days less than in 2019
.
In 2020, due to the overall economic decline due to the epidemic, under the influence of the general environment, the output of air pollution prevention and control equipment has achieved a small increase, an increase of only 0.

It is not difficult to see that the prevention and control of air pollution has been effectively controlled, and monitoring equipment is indispensable
.
.
As far as the prevention and control of air pollution are concerned, monitoring instruments play an important role in it, assuming the responsibility of providing accurate monitoring data and monitoring reports, and its importance is beyond doubt
.
Monitoring instrument.
In order to strengthen the monitoring and control of air pollution, China has built an environmental monitoring air station.
Its main equipment includes online ion chromatography, heavy metals, OC/EC (organic carbon/elemental carbon), single particle time-of-flight mass spectrometer, and VOCs (volatile organic compounds).
), black carbon, turbidity, aerosol lidar, wind profiler radar, microwave radiometer, etc.
, mainly for review and analysis of particulate matter and VOC data

In addition, the editor learned that for the monitoring of atmospheric pollutants, there are flue gas analyzers, toxic and harmful gas monitors, atmospheric heavy metal online analyzers, carbon monoxide analyzers, carbon dioxide analyzers, air detectors , haze monitoring systems, Air quality automatic monitoring system and other gas detection instruments
.
Detector.
Finally, the editor would like to say that under the environment where a series of national policies are intensively promulgated and driven by the strong domestic market demand, China’s air pollution control has made considerable achievements.
The air control industry has shown an unprecedented development momentum.
Pollution prevention equipment also ushered in a rare opportunity for development, and the demand for monitoring instruments has increased significantly
