Announcement
2014 No. 17
Ministry of Environmental Protection of the People's Republic of China
To implement the “Environmental Protection Law of the People's Republic of China”,
protect the environment, protect human health, and regulate environmental
monitoring, two standards, including “Water Quality - Determination of Mercury,
Arsenic, Selenium, Bismuth and Antimony - Atomic Fluorescence Spectrometry”, are
approved as national environmental protection standards, and are published.
The standard names and numbers are as follows.
1. “Water Quality - Determination of Mercury, Arsenic, Selenium, Bismuth and
Antimony - Atomic Fluorescence Spectrometry” (HJ 694-2014);
2. “Soil - Determination of organic carbon - Combustion oxidation nondispersive
infrared absorption method” (HJ 695-2014).
Above standards are implemented since July 1, 2014, and are published by China
Environmental Press. The standard content can be inquired at the website of the
Ministry of Environmental Protection (bz.mep.gov.cn).
Notice is hereby given.

Foreword
To implement the “Environmental Protection Law of the People's Republic of China”
and "Water Pollution Prevention Law of the People's Republic of China”, protect the
environment, protect human health, and regulate the monitoring methods of mercury,
arsenic, selenium, antimony, and bismuth in water, this Standard is formulated.
This Standard specifies the atomic fluorescence spectrometry for determination of
mercury, arsenic, selenium, bismuth, and antimony in water.
This Standard is released for the first time.
Annex A of this Standard is informative.
This Standard was formulated by the Department of Science, Technology and
Standards of Ministry of Environment Protection.
Main drafting organization of this Standard. Nanjing Environmental Monitoring Center.
Verification organizations of this Standard. Jiangsu Environment Monitoring Center,
Jiangsu Physical and Chemical Testing Center, Wuxi Environmental Monitoring
Center Station, Changzhou Environmental Monitoring Center, Zhenjiang
Environmental Monitoring Center Station, and Taizhou Environmental Monitoring
Center.
This Standard was approved by the Ministry of Environmental Protection on March 13,
2014.
This Standard shall be implemented from July 1, 2014.
This Standard shall be interpreted by the Ministry of Environmental Protection.
Water Quality - Determination of Mercury, Arsenic,
Selenium, Bismuth and Antimony –
Atomic Fluorescence Spectrometry
Warning. nitric acid, hydrochloric acid, and perchloric acid have a strong
corrosivity and a strong oxidability, so it shall wear protective equipment when
operating, so as to avoid contact with skin and clothing. The pretreatment
process of all samples shall be carried out in a fume hood.
1 Application scope
This Standard specifies the atomic fluorescence spectrometry for the determination of
mercury, arsenic, selenium, bismuth, and antimony in water.
This Standard applies to the determination of soluble [Translator. dissolved-state] and
total quantity of mercury, arsenic, selenium, bismuth, and antimony in surface water,
groundwater, sewage, and industrial waste water.
According to the method of this Standard, the detection limit of mercury is 0.04μg/L,
the determination lower limit of mercury is 0.16μg/L; the detection limit of arsenic is
0.3μg/L, the determination lower limit of arsenic is 1.2μg/L; the detection limit of
selenium ......
