No. 77 of.2010
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 ambient air ozone.
Six standards, such as the fixed ultraviolet photometry, are national environmental protection standards and are released.
The standard name and number are as follows.
1. Determination of ambient air ozone by ultraviolet photometry (HJ 590-2010);
2. Determination of water quality pentachlorophenols by gas chromatography (HJ 591-2010);
3. Determination of water quality nitrobenzene compounds by gas chromatography (HJ 592-2010);
4. Determination of water quality, elemental phosphorus, phosphorus molybdenum blue spectrophotometry (provisional) (HJ 593-2010);
6. Determination of the total amount of water color developing agent 169 Coupler spectrophotometry (provisional) (HJ 595-2010).
The above standards have been implemented since January 1,.2011 and published by the China Environmental Science Press. The standard content can be found on the website of the Ministry of Environmental Protection.
From the date of implementation of the above standards, the following three national environmental protection standards approved and issued by the former National Environmental Protection Agency shall be abolished.
The name and number are as follows.
1. Determination of ambient air ozone by ultraviolet spectrophotometry (GB/T 15438-1995);
2. Determination of water quality pentachlorophenols by gas chromatography (GB 8972-88);
3. Determination of Total Nitro Compounds in Industrial Wastewater Gas Chromatography (GB 4919-85).
