Foreword
To implement the "People's Republic of China Environmental Protection Law", to protect the ecological environment, safeguarding human health, strengthen the ring of contaminated sites
Environmental protection supervision and management, regulate human health risk assessment of contaminated sites, the development of this standard.
This standard and contaminated sites belong to the following standard series of environmental standards.
"Technical Guidelines for Environmental Site Investigation" (HJ 25.1-2014)
"Site Environmental Monitoring Technical Guidelines" (HJ 25.2-2014)
"Contaminated site soil remediation technology Guidelines" (HJ 25.4-2014)
From the date of implementation of the above standards, "Soil Environmental Quality Industrial Risk Evaluation Criteria" (HJ/T 25-1999) abolished.
This standard specifies the contaminated sites risk assessment principles, contents, procedures, methods and technical requirements.
This standard is developed by the Ministry of Environmental Protection Science, Technology organization.
This standard is mainly drafted by. Environmental Protection Department of the Nanjing Institute of Environmental Sciences, Ministry of Environmental Protection Standards Institute,
Environmental Protection Research Institute of Light Industry, Shanghai Academy of Environmental Sciences, Shenyang Academy of Environmental Sciences.
This standard is approved by the Ministry of Environmental Protection February 19, 2014.
This standard from July 1, 2014 implementation.
The standard explanation by the Ministry of Environmental Protection.
