The Ministry of Ecology and Environment issued 4 national ecological environment standards such as the "measurement of airbag sampling/direct proofing of gas bags for fixed pollution sources and abolition of gasbenzene objects

In order to support the implementation of relevant ecological environmental quality standards and pollutant emissions standards, recently, the Ministry of Ecological Environment released the "Testing Airbag Sampling/Direct Sample Sample-Qi Phase Chromatography" (HJ 1261-2022), "Environment) The measurement of air and exhaust stinky three-point comparative stinky bag "(HJ 1262-2022)," The measurement weight method of the total suspended particles of the environmental air "(HJ 1263-2022) and the" satellite remote sensing fine particles (PM2.5)) 4 national ecological environment standards including the Monitoring Technical Guide "(HJ 1264-2022). "The sampling/Direct Inlet Sample-Qinyan Chromatography method of fixed pollution source of exhaust pyrophenbenzen (HJ 1261-2022) is the first release, which is suitable for fixed pollution sources. The determination of toluene, glycopyrazene, and styrene, and support the implementation of 13 pollutant emission standards such as the Comprehensive Emissions of Atmospheric Pollutants (GB 16297-1996). The method of direct -proofing is used, without the need for pre -processing, the equipment used is highly popular, the method is easy to master, and it has good generality and operability. "Measurement of Environmental Air and Exhaust Smelting Three-Point Comparison Stinking Bag Method" (HJ 1262-2022) is applicable to the measurement of stinks in environmental air, no tissue emissions monitoring point air, and fixed pollution sources, supporting the discharge of evil stink pollutants discharge Eight pollutants such as Standards "(GB 14554-1993) are implemented. Compared with the "three-point comparative stinky bag method of air quality and stinky" (GB/T 14675-1993), it increases the requirements of materials and instruments, experimental personnel, solution formulation, quality assurance and quality control, etc., improve sample classification, sample classification, and The analysis steps and results calculation can effectively improve the accuracy, consistency and comparability of the method, and have the characteristics of simple and easy promotion. The "Measurement of the Method of the total suspended particles of the environment" (HJ 1263-2022) is suitable for manual measurement of the total suspended particulate matter in the air and no organizational emissions monitoring point of environmental air and no organizational emissions. Essence Compared with the "Measurement of the Total Suspending particles of the Environmental Air" (GB/T 15432-1995), the requirements of the specified reference files, terms and definitions, sample preservation, quality assurance and quality control and precautions are added to refine the samples to refine the samples , Analyze the steps, results and calculations, add strict balance requirements, and further improve the accuracy of the monitoring data of the total air suspended particulate matter in the environment, and provide the necessary basis for the analysis of particulate matter sources and air quality forecast. "Satellite Remote Fine Fine particles (PM2.5) Monitoring Technical Guide" (HJ 1264-2022) is first released, which is suitable for monitoring of satellite remote sensing fine particles in the land area as a supplement to the ground monitoring method and used to master the large-scale fine particles spatial distribution Law and change trends provide strong technical support for air pollution prevention and control. The implementation of the above four standards is of great significance for further improving the standard system of ecological environment monitoring standards, standardizing ecological environment monitoring behaviors, improving the quality of ecological environment monitoring data, serving ecological environment supervision and law enforcement, and promoting ecological environmental protection and ensuring human health.
