In order to implement the Environmental Protection Law of the People's Republic of China, protect the ecological environment, safeguard human health, and standardize ecological environment monitoring work, the Ministry of Ecology and Environment issued four national environmental protection standards, including the Technical Specification for Numerical Forecasting of Environmental Air Quality, on May 18, 2020, which will be implemented from August 15, 2020.

The standard name and number are attached:

Technical Specification for Numerical Forecasting of Environmental Air Quality（HJ 1130-2020).pdf.pdf

Portable UV absorption method for determination of sulfur dioxide in exhaust gas from fixed pollution sources（HJ 1131-2020).pdf.pdf

Determination of arsenic, selenium, bismuth, and antimony in ambient air and exhaust particulate matter by atomic fluorescence method（HJ 1133-2020).pdf.pdf

Portable UV absorption method for the determination of nitrogen oxides in exhaust gas from fixed pollution sources(HJ 1132-2020).pdf.pdf

The four standards are all released for the first time, mainly involving the numerical forecasting of environmental air quality and monitoring of environmental air and fixed pollution source exhaust gas. They are implemented in conjunction with relevant environmental air quality standards and pollutant emission standards to support the victory of the blue sky defense battle.
