In order to implement the "Environmental Protection Law of the People's Republic of China", protect the environment, and protect human health, we now approve the measurement of water quality polycyclic aromatic hydrocarbons.
Eighteen standards, such as fixed liquid extraction and solid phase extraction high performance liquid chromatography, are national environmental protection standards and are released.
The standard name and number are as follows.
I. Determination of Polycyclic Aromatic Hydrocarbons by Liquid-Liquid Extraction and Solid Phase Extraction High Performance Liquid Chromatography (HJ 478-2009);
2. Determination of nitrous oxides (nitrogen oxides and nitrogen dioxide) - Determination of naphthalene diamine hydrochloride spectrophotometric method (HJ 479-
2009);
