Zhuzhou invests 300,000 new 2 PM2.5 automatic analyzers

Introduction: Zhuzhou City Environmental Protection Bureau invested 300,000 yuan, installed two PM2.5 automatic analyzer. And plans to increase investment in succession, and strive to install the analyzer in all ambient air automatic monitoring points. At present, these two PM2.5 analyzers have been put into trial operation and are in the debugging stage.

It is reported that the Zhuzhou Environmental Protection Bureau invested 300,000 yuan, installed two PM2.5 automatic analyzers, and became the second city in Hunan after the Changsha city to achieve automatic air quality monitoring of PM2.5. The equipment is installed in two environmental air quality monitoring points at the Tiantai Shanzhuang and the city monitoring stations, and plans to increase the investment in succession, and strive to install the analyzer in all the ambient air automatic monitoring points. At present, these two PM2.5 analyzers have been put into trial operation and are in the debugging stage.

"PM" is also the inhalable particle in the ambient air and "2.5" is the diameter of the particle. In the past, the national environmental air quality standard was only PM10, and the Ministry of Environmental Protection only assessed PM10 in the ambient air. Therefore, environmental protection agencies around the world only monitor pollutants with a diameter of 10 microns and below that of inhalable particles in the ambient air, and pay attention to control of emissions of pollutants such as dust and dust when controlling air pollution. However, with the improvement of the environmental quality and changes in the social life, people realize that the PM2.5 in the ambient air more inhalable particulate matter is more easily through the respiratory tract directly into the human lungs, causing great harm to human health, so the PM2. 5 monitoring is very necessary. The "Ambient Daily Air Quality Index (AQI) Daily Technical Specification" (three drafts of drafts) revised by the Ministry of Environmental Protection this year has already added new standards for PM2.5 and ozone in the ambient air. After the formal promulgation and implementation, there will be new The corresponding assessment requirements were introduced.
