5 ecological environment standards released

In order to support the implementation of relevant water pollutant discharge standards, soil risk management and control standards, monitoring of water ecology in key river basins, and to serve solid waste treatment and disposal, the Ministry of Ecology and Environment recently issued five national ecological environment standards
.

These five standards are all released for the first time
.
Among them, "Determination of 13 kinds of anilines and 2 kinds of benzidine compounds in soil and sediments by liquid chromatography-triple quadrupole mass spectrometry" (HJ 1210-2021) is suitable for 13 kinds of anilines and 2 kinds of benzidine compounds in soil and sediments The determination of various 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.
The standard blank of monitoring and analysis methods for similar compounds can provide monitoring technical support for soil risk management and control of construction land and soil pollution remediation
.

"Determination of Inorganic Elements in Solid Wastes by Wavelength Dispersive X-ray Fluorescence Spectrometry" (HJ 1211-2021) is applicable to 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 Membrane-Microscopic Counting Method" (HJ 1215-2021), "Determination of Phytoplankton in Water Quality" The release and implementation of standards such as 0.
1ml Counting Box - Microscope Counting Method (HJ 1216-2021) will further improve the ecological environment monitoring standard system, provide relevant monitoring method support for standardizing the ecological environment monitoring work and in-depth combat of pollution prevention and control
