We have noticed that the frequency of issuing environmental standards has accelerated recently. Recently, the Ministry of Ecology and Environment has issued three more announcements, releasing a total of 12 national environmental protection standards, covering methods and technical requirements for the determination of volatile organic compounds in soil, water quality, and ambient air.

The standard name and number are as follows.

1、 Determination of Aldehydes and Ketones in Soil and Sediments by Liquid Chromatography (HJ 997-2018). pdf;

This standard specifies the liquid chromatography method for determining aldehydes and ketones in soil and sediment. Appendix A of this standard is normative, while Appendices B to D are informative. This standard is for publication.

　　2、 Determination of volatile phenols in soil and sediment -4-aminoantipyrine spectrophotometric method (HJ 998-2018). pdf；

This standard specifies the 4-aminoantipyrine spectrophotometric method for determining volatile phenols in soil and sediment. Appendix A of this standard is an informative appendix. This standard is for publication.

　　3、 Determination of Fluorine in Solid Waste by Alkali Melting Ion Selective Electrode Method (HJ 999-2018). pdf；
