Reference
Endpoint:
toxicity to aquatic algae and cyanobacteria
Type of information:
other: Database of chemical substances (Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Qualifier:
no guideline followed
Version / remarks:
For the assessment of hazardous properties can be used relevant alternative methods (non – testing methods - read-across/chemical categories, chemistry considerations or(Q)SAR etc.).
If the outputs from the application of alternative methods are not sufficiently conclusive, will be used recommended test method. First, the methods of in vitro and then the in vivo methods.
Data could be usable, access to the study and resolution of property rights should be ensured.
Recommended test method according to Regulation 440/2008: C.3 Freshwater algae and cyanobacteria, growth inhibition test (OECD TG 201)

Additional information

For the assessment of hazardous properties can be used relevant alternative methods (non – testing methods - read-across/chemical categories, chemistry considerations or(Q)SAR etc.).

If the outputs from the application of alternative methods are not sufficiently conclusive, will be used recommended test method.  First, the methods of in vitro and then the in vivo methods.

Data could be usable, access to the study and resolution of property rights should be ensured.
