[ Policies and Regulations of Chemical Machinery and Equipment Network ] Standards are the technical support for economic activities and social development, and are an important aspect of the national basic system
.
Environmental protection standards are provisions for the technical attributes of various things that need to be regulated in the field of environmental protection.
After several years of efforts, China's ecological environment standard system is gradually being established
.

Recently, the Ministry of Ecology and Environment has carried out "Ion Chromatography for the Determination of Acrylic Acid in Water Quality", "Technical Specifications for Continuous Automatic Monitoring of Organic Carbon and Elemental Carbon in Ambient Air Particulate Matter (PM2.
5)", "Water-soluble Ions in Ambient Air Particulate Matter (PM2.
5)" Compilation of four national ecological environment standards, including Technical Specifications for Continuous Automatic Monitoring and Technical Specifications for Continuous Automatic Monitoring of Inorganic Elements in Ambient Air Particulate Matter (PM2.
5), and a draft for soliciting opinions from the whole society
.

Original text of the announcement

"Determination of Acrylic Acid in Water Quality by Ion Chromatography (Draft for Comment)" specifies the ion chromatography method for the determination of acrylic acid in water, which is quasi-applicable to the determination of acrylic acid in surface water, groundwater, domestic sewage and industrial wastewater.
When the injection volume is 25 μl, The detection limit of the method was 0.
08 mg/L, and the lower limit of determination was 0.
32 mg/L
.

　　"Technical Specifications for Continuous Automatic Monitoring of Organic Carbon and Elemental Carbon in Ambient Air Particulate Matter (PM2.
5) (Draft for Comments)" specifies the method, principle and method of continuous automatic monitoring system for organic carbon and elemental carbon in ambient air particulate matter (PM2.
5).
Technical requirements such as system composition, technical performance, installation, commissioning, trial operation and acceptance, daily operation and maintenance of the system, quality assurance and quality control, and data validity judgment
.
It is suitable for the installation, acceptance, operation management and quality control of the continuous automatic monitoring system for organic carbon and elemental carbon in ambient air particulate matter (PM2.
5) using thermal-optical correction method and thermal-optical attenuation method
.

　　"Technical Specifications for Continuous Automatic Monitoring of Water-Soluble Ions in Ambient Air Particulate Matter (PM2.
5) (Draft for Comment)" specifies the method, principle, system composition, and technology of a continuous automatic monitoring system for water-soluble ions in ambient air particulate matter (PM2.
5).
Technical requirements for performance, installation, commissioning, trial operation and acceptance, daily system operation and maintenance, quality assurance and quality control, data validity judgment, waste liquid disposal,
etc.
It is suitable for the installation, acceptance and operation of continuous automatic monitoring system for water-soluble ions (Cl-, NO3-, SO42-, Na+, NH4+, K+, Mg2+, Ca2+) in ambient air particulate matter (PM2.
5) using ion chromatography Management and Quality Control
.

　　"Technical Specifications for Continuous Automatic Monitoring of Inorganic Elements in Ambient Air Particulate Matter (PM2.
5) (Draft for Comment)" specifies the method, principle, system composition, technical performance, Technical requirements such as installation, commissioning, trial operation and acceptance, daily operation and maintenance of the system, quality assurance and quality control, and data validity judgment
.
It is suitable for the installation, acceptance, operation management and quality control of the continuous automatic monitoring system for inorganic elements in ambient air particulate matter (PM2.
5) using energy dispersive X-ray fluorescence spectroscopy
.

　　The release of the relevant standards of the Ministry of Ecology and Environment is the key to help in-depth fight against pollution, which is conducive to protecting natural resources and improving the utilization rate of resources and environment, and further standardizing China's ecological environment monitoring work
.
