Hazardous waste identification standard
, leaching toxicity identification
Identification standard for hazardous wastesIdentification for extraction procedure toxicity1 Subject content and scope of application
1.1 Subject content
This standard specifies the leaching toxicity standard value for identifying one of the hazardous characteristics of dangerous substances. 1.2 Scope of application
GB5085.3-1996
replaces the relevant parts of
in GB5085-85 and GB12502-90
This standard applies to any production process and living environment Identification of leaching toxicity of generated solid hazardous wastes. 2 Reference standards
GB/T15555.1~15555.11 Solid waste leaching toxicity determination method 3 Terminology
3.1 Hazardous waste
refers to corrosive, acute toxicity, leaching toxicity, reactivity, Waste with one or more hazardous characteristics such as infectious and radioactive. 3.2 Leaching toxicity
The leaching toxicity referred to in this standard refers to the leaching of solid hazardous wastes in water, in which harmful substances migrate and transform, polluting the environment. The toxicity of leached harmful substances is called leaching toxicity.
4 Identification value of leaching toxicity
If the concentration of any hazardous component in the leachate exceeds the concentration value listed in Table 1, the waste is a hazardous waste with leaching toxicity. Table 1

* Temporarily refer to the national standards for water quality measurement, The corresponding national standards will be implemented after the national standard methods for solid matter are released. *For the time being, refer to "Ore and Non-ferrous Metal Analysis Manual", page 146, compiled by the Analysis Office of Beijing Mining and Metallurgical Research Institute, Metallurgical Industry Press (1990). After the national standard methods for measuring solids are released, the corresponding national standards 6 will be implemented
The environmental protection administrative departments of the local people's governments at or above the county level are responsible for the supervision and implementation. 240
