The Ministry of Ecology and Environment issued 5 national ecological and environmental standards including "Determination of 28 Organophosphorus Pesticides in Water Quality by Gas Chromatography-Mass Spectrometry"

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.

"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

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 "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

"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)

"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

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
