In order to support the implementation of relevant water pollutant discharge standards, soil risk management and control standards, and monitoring of water ecology in key river basins, as well as serving solid waste treatment and disposal, the Ministry of Ecology and Environment recently issued 5 national ecological environment standards
.
These five standards are all released for the first time
.
Among them, "Determination of 13 anilines and 2 benzidine compounds in soil and sediments by liquid chromatography-triple quadrupole mass spectrometry" (HJ 1210-2021) is suitable for 13 anilines and 2 anilines in soil and sediments.
The determination of benzidine compounds 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), which will fill the gap between anilines and benzidines in China's soil and sediments.
"Determination of Inorganic Elements in Solid Wastes by Wavelength Dispersive X-ray Fluorescence Spectrometry" (HJ 1211-2021) is suitable for 16 inorganic elements and Determination of 7 oxides
.
Compared with the existing monitoring and analysis method standards for inorganic elements in solid waste, the scope of application of this standard has increased sludge, contaminated soil and other media.
The pretreatment method is simple and the analysis speed is fast, which helps to improve the analysis efficiency
In addition, "Microcoulometric Method for Determination of Adsorbable Organic Halogens (AOX) in Water Quality" (HJ 1214-2021), "Determination of Phytoplankton in Water Quality by Membrane-Microscopic Counting Method" (HJ 1215-2021), "Determination of Phytoplankton in Water Quality" The release and implementation of standards such as 0.
