[ Policies and Regulations of Chemical Machinery Equipment Network ] Recently, in order to further improve the ecological environment standard system and standardize the ecological environment monitoring work, the Ministry of Ecology and Environment issued the "Determination of 13 anilines and 2 benzidine compounds in soil and sediment by liquid chromatography.
- Triple Quadrupole Mass Spectrometry (HJ 1210-2021), Determination of Inorganic Elements in Solid Waste, Wavelength Dispersive X-ray Fluorescence Spectrometry (HJ 1211-2021), Microcoulombic Determination of Adsorbable Organic Halogens (AOX) in Water Quality Law" (HJ 1214-2021), "Determination of Phytoplankton in Water Quality Filter Membrane-Microscopic Counting Method" (HJ 1215-2021), "Determination of Phytoplankton in Water Quality 0.
1 ml Counting Box-Microscopic Counting Method" (HJ 1216-2021) and other five national ecological environment standards, all of which are released for the first time
.

Chemical Machinery and Equipment Network Policies and Regulations Chemical Machinery and Equipment

"Determination of 13 anilines and 2 benzidine compounds in soil and sediments by liquid chromatography-triple quadrupole mass spectrometry" (HJ 1210-2021) specifies the determination of anilines and benzidine compounds in soil and sediments liquid chromatography-triple quadrupole mass spectrometry for benzidine, aniline, 2-methoxyaniline, 4-nitroaniline, 3-nitroaniline, 4-chloroaniline, 2- Determination of naphthylamine, 3-chloroaniline, 3,3'-dichlorobenzidine and N-nitrosodiphenylamine, a total of 13 anilines and 2 benzidine compounds
.
The standard supports the implementation of soil risk management and control standards such as "Soil Environmental Quality Construction Land Soil Pollution Risk Management and Control Standards (Trial)" (GB 36600-2018)
.

"Determination of Inorganic Elements in Solid Wastes by Wavelength Dispersive X-ray Fluorescence Spectrometry" (HJ 1211-2021) specifies the determination of 16 kinds of inorganic elements in solid wastes, including sludge, polluted soil, fly ash, soot, tailings waste rock and smelting slag.
Wavelength Dispersive X-ray Fluorescence Spectroscopy of Elements and 7 Oxides, Suitable for 16 Inorganic Elements and 7 Oxides in Solid Waste, Sludge, Contaminated Soil, Fly Ash, Soot, Tailings Waste Rock and Smelting Slag Determination
.
This standard supports the implementation of standards such as "Agricultural Sludge Pollutant Control Standard" (GB 36600-2018), "Technical Specification for Environmental Protection of Solid Waste Co-processing in Cement Kilns" (HJ 662-2013) and other standards.
Compared with the monitoring and analysis method standard of this standard, the scope of application of this standard increases the medium such as sludge and polluted soil.
The pretreatment method is simple and the analysis speed is fast, which helps to improve the analysis efficiency
.

"Microcoulometric Method for Determination of Adsorbable Organic Halogens (AOX) in Water Quality" (HJ 1214-2021) specifies the microcoulometric method for the determination of adsorbable organic halogens in surface water, groundwater, domestic sewage and industrial wastewater, which is suitable for surface water, groundwater , Determination of adsorbable organic halogens in domestic sewage and industrial wastewater
.
This standard supports the implementation of the "Integrated Wastewater Discharge Standard" (GB 8978-1996) and other standards
.
Compared with "Microcoulometric Method for Determination of Adsorbable Organic Halogens (AOX) in Water Quality" (GB/T 15959-1995), this standard adjusts the scope of application, refines calibration, sample measurement and result presentation, etc.
, and increases interference.
and elimination, quality assurance and quality control, etc.
, to better meet the actual needs of ecological environment monitoring
.

　　"Determination of Phytoplankton in Water Quality Filter Membrane-Microscopic Counting Method" (HJ 1215-2021), "Determination of Phytoplankton in Water Quality 0.
1 ml Counting Box-Microscopic Counting Method" (HJ 1216-2021) respectively stipulate the determination of phytoplankton in surface water.
The filter-microscope counting method and the filter-microscope counting method for the determination of phytoplankton in surface water are suitable for the determination of phytoplankton in surface water
.

　　The release and implementation of the above five standards is an important measure to deepen the battle against pollution, providing relevant testing methods for the implementation of relevant water pollutant discharge standards, soil risk management and control standards, monitoring of water ecology in key river basins, and solid waste treatment and disposal services.
