Rules for classification and labelling of chemicals —Part 28: Hazardous to the aquatic environment
1 Scope
This part of GB 30000 stipulates the terms and definitions, classification standards, judgment logic and labels of chemicals hazardous to the aquatic environment.
This part is applicable to the classification and labelling of chemicals hazardous to the aquatic environment according to the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (Rev.4) (hereinafter referred to as “GHS”).

3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the term and definition given in GB 13690 and the following apply.
3.1.1
acute aquatic toxicity
nature of the substance that is hazardous to aquatic organisms in contact with it for a short time
3.1.2
acute (short-term) hazard
hazard caused by acute toxicity of chemicals to aquatic organisms exposed to water for a short time
3.1.3
availability
degree to which a substance becomes a soluble or decomposable species; availability of metal: degree to which the metal ions in the metal (M) compound can be decomposed from the rest of the compound (molecule)
3.1.4
bioavailability; biological availability
degree to which substances are absorbed by an organism and distributed in an area of the organism
3.1.5
bioaccumulation
net result from the process that substances are absorbed, transformed and discharged by an organism through all contact routes (i.e., air, water, sediment/soil and food)
3.1.6
bioconcentration
net result from the process that substances are absorbed, transformed and discharged by an organism in water-borne contact
3.1.7
chronic aquatic toxicity
nature of a substance that is hazardous to aquatic organisms in contact with it for a period dependent on the lifecycle of organisms
3.1.8
complex mixtures
multi-component substances
complex substances
mixtures of single substances with different solubility and physicochemical properties in a complex manner, in most cases, described as homologues with a specific range of carbon chain length/number of substitution degree
