[ Policies and Regulations of Chemical Machinery and Equipment Network ] On the 5th, the fifth meeting of the 13th National People's Congress was successfully held.
This year's government work report pointed out that in the field of ecological civilization construction, the country has carried out in-depth pollution prevention and control battles.
Major pollutants Emissions continued to decline, and the quality of the ecological environment was significantly improved
.
With the orderly progress of the carbon peak carbon neutralization work, the carbon peak action plan was also introduced at this meeting
.

Chemical Machinery Equipment Network Policies and Regulations

In order to increase the research and development, promotion and application of green and low-carbon technologies, curb high energy consumption and high emissions, and promote energy conservation and carbon reduction, a series of ecological and environmental quality standards and pollutant discharge standards have been introduced
.
Recently, the Ministry of Ecology and Environment released 10 national eco-environmental standards, which are listed below
.

"Gas Chromatography for Determination of Pyridine in Ambient Air and Waste Gas" (HJ 1219-2021)

This standard is the first to be issued, and specifies the gas chromatography method for the determination of pyridine in ambient air, air at monitoring points of fugitive emissions, and waste gas emitted by organized pollution sources.
This method has the characteristics of fast analysis speed, high resolution, and good separation
.

　　"Determination of Six Volatile Carboxylic Acid Compounds in Ambient Air by Gas Chromatography-Mass Spectrometry" (HJ 1220-2021)

　　This standard is also released for the first time, and can support the implementation of pollutant discharge standards such as "Synthetic Resin Industry Pollutant Emission Standard" (GB 31572-2015), "Petrochemical Industry Pollutant Emission Standard" (GB 31571-2015)
.
It is suitable for the determination of 6 kinds of volatile carboxylic acid compounds in ambient air and the air of fugitive emission monitoring points.
The method is convenient and sensitive
.

　　"Gravimetric Method for Determination of Moisture and Dry Matter Content of Solid Waste" (HJ 1222-2021)

　　This standard is published for the first time and can provide a more scientific method for the determination of moisture and dry matter content for the analysis, treatment and disposal of solid waste.
It is not suitable for moisture and dry matter content in solid waste samples with high volatile organic content, flammable and explosive measurement
.

　　"Determination of Organochlorine Pesticides in Ambient Air by High Resolution Gas Chromatography-High Resolution Mass Spectrometry" (HJ 1224-2021)

　　This standard is published for the first time and is applicable to the determination of 25 organochlorine pesticides in the gaseous phase and particulates of ambient air
.
As an ultra-trace analysis method for organochlorine pesticides, this standard can provide a reliable basis for China to implement the Stockholm Convention on Persistent Organic Pollutants and carry out low-concentration sample monitoring
.

　　"Chemiluminescence method for automatic determination of ozone in ambient air" (HJ 1225-2021)

　　This standard is published for the first time and applies to the automatic determination of ozone in ambient air
.
This standard has strong anti-interference ability, has good consistency with ultraviolet spectrometry, and can be used as a useful supplement to ultraviolet spectrometry
.

　　"Gravimetric Method for Determination of Dust Fall in Ambient Air" (HJ 1221-2021)

　　This standard refines the provisions on sampling point layout in the Gravimetric Method for Determination of Dust Fall in Ambient Air (GB/T 15265-94), revises and improves the equipment and quality control requirements, improves the operability of the method, and can meet the current atmospheric requirements.
Dust monitoring needs in environmental management work
.

　　"Determination of Sulfur in Water by Methylene Blue Spectrophotometry" (HJ 1226-2021)

　　Compared with "Methylene Blue Spectrophotometric Method for Determination of Sulfur in Water" (GB/T 16489-1996), this standard has revised the scope of application and detection limit, and added pretreatment methods, etc.
, which can support the "Environmental Quality Standard for Surface Water".
"(GB 3838-2002), "Comprehensive Sewage Discharge Standard" (GB 8978-1996) and other water environment quality and water pollutant discharge standards are implemented, which are applicable to surface water, groundwater, domestic sewage, industrial wastewater and sulfide in seawater.
Determination
.

　　Portable Gas Chromatography-Mass Spectrometry for Emergency Determination of Volatile Organic Compounds in Ambient Air (HJ 1223-2021), Portable Headspace/Gas Chromatography-Mass Spectrometry for Emergency Determination of Volatile Organic Compounds in Water Quality (HJ 1227-2021) and Sudden Technical Specifications for Emergency Monitoring of Environmental Incidents (HJ 589-2021), applicable to emergency monitoring of environmental emergencies
.
HJ 1223-2021 and HJ 1227-2021 are released for the first time, which can conduct on-site qualitative analysis and accurate quantification of VOCs
.
HJ 589-2021 is the first revision, which specifies the technical requirements for the key links of emergency monitoring of environmental emergencies
.
The three standards can provide technical support for emergency response to environmental emergencies
.

　　"Double carbon" has always been a hot word in the field of ecological environment construction in recent years.
The release and implementation of the above 10 standards is of great importance for further improving the ecological environment monitoring standard system, improving the quality of environmental monitoring data, promoting ecological environment protection and ensuring human health.
At the same time, it is also of great significance to implement the carbon peaking action plan and accelerate the formation of green production and life>
.
