environmental monitoring

atmospheric environmental monitoring

Atmospheric environment monitoring is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and their impact on the environment. It is to reduce their adverse effects and harm to human society. Air pollution monitoring items are divided into particulate pollutant monitoring and gaseous pollutant monitoring. Among them, gaseous pollutant monitoring includes SO2, NOx, CH4, CO, O3, CH2O, H2S, NH3, HCI, C2H2, etc.

Vehicle exhaust monitoring

The contribution rate of motor vehicle exhaust to air pollution is close to 40%. The exhaust mainly includes CO, HC, CO2, NOx and solid suspended particulate matter. The harm of automobile exhaust to the environment and humans is self-evident. With the increase of automobile ownership, automobile exhaust pollution is becoming increasingly serious. Legislation on automobile exhaust emissions is imperative, and countries around the world have also established corresponding laws and regulations. At present, my country's fourth national emission standard is about to be introduced, and it is a general trend of unity.

carbon monitoring

On September 22, 2020, President Xi Jinping stated at the general debate of the 75th session of the United Nations General Assembly that China will increase its nationally determined contribution and adopt more powerful policies and measures. China's carbon emissions strive to achieve "carbon peak" by 2030, and strive to achieve "carbon neutrality" by 2060.

Scientifically and accurately monitoring greenhouse gas concentrations, verifying and supporting the compilation of emission inventories, and improving the accuracy of greenhouse gas inventory compilation are the basis for greenhouse gas emission statistics and verification. In September 2021, the Ministry of Ecology and Environment issued the "Carbon Monitoring and Evaluation Pilot Work Plan"(Environmental Security Bureau Monitoring Letter [2021] No. 435) to carry out greenhouse gas monitoring, which can continue to provide scientific assessment of the effectiveness of my country's carbon peak and carbon neutrality actions. Carbon emission accounting provides data support.
