In 2022, 10 new standards for ambient air and exhaust gas testing will be implemented

On March 5, 2022, the Ministry of Ecology and Environment issued 10 national ecological and environmental standards on ambient air and exhaust gas testing, which will be implemented
on March 1, 2022 and June 1, 2022, respectively.

The release and implementation of the 10 standards is of great significance
for further improving the ecological environment monitoring standard system, standardizing the ecological environment monitoring behavior, improving the quality of environmental monitoring data, serving the ecological environment supervision and law enforcement, promoting ecological environmental protection and protecting human health.

The 10 standards involving laboratory instruments mainly include: gas chromatography, gas chromatography - mass spectrometer, high resolution gas chromatography, high resolution mass spectrometer, spectrophotometer, portable gas chromatography - mass spectrometer, portable headspace injector, analytical balance, ultrasonic cleaner, nitrogen blower, muffle furnace, oven, dryer, solid phase extraction device, ozone analyzer, gas dilution meter, thermal desorption, etc
.

10 testing standards for ambient air and exhaust gases implemented in 2022 "Determination of ambient air and exhaust gas pyridine Gas chromatography" (HJ 1219-2021) "Determination of 6 volatile carboxylic acid compounds in ambient air Gas chromatography-mass spectrometry" (HJ 1220-2021) "Determination of dust reduction in ambient air Gravimetric method" (HJ 1221-2021) "Determination of moisture and dry matter content in solid waste Gravimetric method" (HJ 1222-2021) Emergency Determination of Volatile Organic Compounds in Ambient Air Portable Gas Chromatography-Mass Spectrometry (HJ 1223-2021) Determination of Ambient Air Organochlorine Pesticides High Resolution Gas Chromatography-High Resolution Mass Spectrometry (HJ 1224-2021) Automatic Determination of Ambient Air Ozone Chemiluminescence Method (HJ 1225-2021) Determination of Water Quality Sulphides Methylene Blue Spectrophotometry (HJ 1226-2021) Water Quality Emergency Determination of Volatile Organic Compounds Portable Headspace/Gas Chromatography-Mass Spectrometry (HJ 1227-2021) Technical Specification for Emergency Monitoring of Environmental Emergencies (HJ 589-2021) of which "Determination of Ambient Air and Exhaust Gas Pyridine Gas Chromatography" (HJ 1219-2021) is newly released, suitable for the determination of pyridine in ambient air and fugitive emission exhaust gases, with fast
analysis speed.

High sensitivity, good resolution and other characteristics
.

"Determination of 6 Volatile Carboxylic Acid Compounds in Ambient Air Gas Chromatography-Mass Spectrometry" (HJ 1220-2021) is newly released, suitable for 6 volatile carboxylic acid compounds in ambient air and fugitive emission monitoring point air, with simple methods and high sensitivity, which can support the "Emission Standards for Pollutants in the Synthetic Resin Industry" (GB 31572-2015) and the "Emission Standards for Petrochemical Pollutants" (GB).
31571-2015) and other pollutant emission standards were implemented
