In order to implement the Environmental Protection Law of the People's Republic of China and standardize ecological environment monitoring work, four standards, including the "Determination of Nitrate Mist from Fixed Pollution Source Waste Gas by Ion Chromatography Method", are now approved as national ecological environment standards and published.
The standard name and number are as follows.
1、 Determination of Nitric Acid Mist in Waste Gas from Fixed Pollution Sources by Ion Chromatography (HJ 1361-2024)
2、 Determination of Phosphate Mist in Waste Gas from Fixed Pollution Sources by Ion Chromatography (HJ 1362-2024)
3、 Water quality - Determination of benzyl ether and methyl tert butyl ether - Purge trap/gas chromatography-mass spectrometry method (HJ 1363-2024)
4、 Determination of Abamectin B1a and Abamectin B1b in Water Quality by High Performance Liquid Chromatography (HJ 1364-2024)
The above standards will be implemented from May 1, 2025, and the content of the standards can be found on the website of the Ministry of Ecology and Environment.
