3 terms and definitions, abbreviations
3.1 Terms and definitions
The following terms and definitions defined in GB 30000.28 apply to this document.
3.1.1
Acute aquatic toxicity acuteaquatictoxicity
It can damage the organism that touches the substance in water for a short time, which is the nature of the substance itself.
3.1.2
Chronic aquatic toxicity chronicaquatictoxicity
It can cause harmful effects on organisms that have been exposed to the substance for a long time in water, and is the nature of the substance itself.
Note. The contact time is determined by the life cycle of the organism.
3.1.3
Difficult substance difficultsubstances
Substances that are difficult to test in aquatic systems.
Note. The main performance is that the standard test method is not applicable, or it is difficult to give a proper explanation of the test data.
3.2 Abbreviations
The following abbreviations apply to this document.
BCF. Bioconcentration factor
EC50. half effect concentration (Concentrationfor50%ofmaximaleffect)
ECx. x% effect concentration (Concentrationforx%ofmaximaleffect)
