    According to the official account of the Ministry of Ecology and Environment, in order to support the implementation of relevant water environmental quality standards and water pollutant discharge standards, the Ministry of Ecology and Environment recently issued the "Determination of 28 Organophosphorus Pesticides in Water Quality by Gas Chromatography-Mass Spectrometry" (HJ 1189-2021), "Water Quality Sterilization Biological Indicators (Bacillus Subtilis Black Variety) Identification Biological Detection Method" (HJ 1190-2021), "Water Quality Determination of Azide Spectrophotometric Method" (HJ 1191-2021), "9 Water Quality Determination of Alkylphenol Compounds and Bisphenol A Solid Phase Extraction/High Performance Liquid Chromatography (HJ 1192-2021), "Water Quality Determination of Indium, Graphite Furnace Atomic Absorption Spectrophotometry" (HJ 1193-2021), etc.
    5 items National Ecological Environment Standard

    .

    "Determination of 28 Organophosphorus Pesticides in Water Quality by Gas Chromatography-Mass Spectrometry" (HJ 1189-2021) is the first release and is suitable for the determination of 28 organophosphorus pesticides in surface water, groundwater, sea water, domestic sewage and industrial wastewater
    .
    This standard applies to many analysis objects and has a good separation effect.
    It can support the implementation of water environmental quality standards such as "Surface Water Environmental Quality Standard" (GB 3838-2002) and "Groundwater Quality Standard" (GB/T 14848-2017).
    It is a pesticide industry The formulation and revision of water pollutant discharge standards and the refined management of corporate pollutant discharge provide technical support for monitoring

    .

    The Biological Test Method for the Identification of Water Quality Sterilization Biological Indicators (Bacillus subtilis Black Variety) (HJ 1190-2021) is the first release and is suitable for the evaluation of the sterilization effect of wastewater in microbiological laboratories
    .
    The issuance and implementation of this standard can support the biological testing of the sterilization effect of microbiological laboratory wastewater, which is conducive to the implementation of the "Biosafety Law", strengthens the prevention of biosafety risks, and protects the ecological environment

    .

    The "Water Quality Determination of Azide Spectrophotometric Method" (HJ1191-2021) is the first release and is suitable for the determination of azide in surface water, groundwater, domestic sewage and industrial wastewater
    .
    Azide is highly toxic and dangerous

    .
    The issuance and implementation of this standard is conducive to the refined management and control of water pollutants discharged from azide by related industries, and plays an important role in protecting the ecological environment and safeguarding human health

    .

    "Water Quality Determination of 9 Alkylphenol Compounds and Bisphenol A" Solid Phase Extraction/High Performance Liquid Chromatography (HJ 1192-2021) is the first release, applicable to 9 species in surface water, groundwater, domestic sewage and industrial wastewater The determination of alkylphenol compounds and bisphenol A can support the implementation of water pollutant discharge standards such as the "Petrochemical Industry Pollutant Discharge Standard" (GB 31571-2015)
    .
    Alkylphenol compounds and bisphenol A are typical endocrine disruptors, which are toxic, persistent, and bioaccumulative.
    China has banned the production of related products and has set limit indicators in the pollutant emission standards of related industries

    .
    This standard release embodiment, help to strengthen the water pollutant emissions control, alkylphenol compounds and bisphenol A pollution monitoring method provides support

    .

    "Determination of Indium in Water Quality by Graphite Furnace Atomic Absorption Spectrophotometry" (HJ 1193-2021) is the first release and is suitable for the determination of indium in surface water, groundwater and industrial wastewater
    .
    With the development of high-tech industries, the use of indium has become increasingly widespread, and attention needs to be paid to the impact of indium-containing pollutants on the ecological environment

    .
    This standard has strong selectivity and high sensitivity, and the prices of instruments and equipment used and analysis costs are relatively low

    .
    The issuance and implementation of this standard can provide technical support for the determination of indium in water pollutants in the water environment and related industries

    .

    The issuance and implementation of the above five standards is of great significance for further improving the ecological environment monitoring standard system, standardizing ecological environment monitoring behavior, improving the quality of environmental monitoring data, serving ecological environment supervision and law enforcement, promoting ecological environmental protection and safeguarding human health
