announcement
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);
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);
5. Determination of the total amount of water-based developer and its oxides - Iodine-starch spectrophotometry (interim) (HJ 594-2010);
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).

Foreword
To protect the environment and protect the human body in order to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on Water Pollution Prevention and Control
This standard is established for the determination of health and standardization of pentachlorophenol in water.
This standard specifies the gas chromatographic method for the determination of pentachlorophenol and pentachlorophenolate in water.
This standard is a revision of the "Gas Chromatography for the Determination of Pentachlorophenol in Water" (GB 8972-88).
This standard was first published in 1988. The original standard was drafted by the Ministry of Railways Labor Health Research Institute. This is the first revision. Revision
The main contents are as follows.
-- Expanded the scope of application;
-- Added capillary column analysis method;
-- modified the quantitative method;
-- Added provisions for quality control and quality assurance.
From the date of implementation of this standard, the national environmental protection standard “Water quality approved and issued by the former National Environmental Protection Agency on March 26, 1988.
Determination of pentachlorophenol gas chromatography (GB 8972-88) is abolished.
Appendix A of this standard is an informative annex.
This standard was formulated by the Science and Technology Standards Department of the Ministry of Environmental Protection.
This standard is mainly drafted by. Qingdao Environmental Monitoring Center Station.
This standard is verified by. Jinan Environmental Protection Monitoring Station, Zibo Environmental Monitoring Station,
