Description of key information
The test substance,Ashes (residues) - Biomass Combustion, was tested for growth inhibition on algae Desmodesmus subspicatus.
The test was performed according to method C.3 - Algal Inhibition Test, Council Regulation (EC) No. 440/2008, published in O.J.L 142, 2008.
GLP study
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
Additional information
The study was performed without the analytical determination of the test substance concentrations. Only the concentrations of metals in the highest loading rate 100mg·L-1 were analysed in the limit test. For all evaluations and results the loading rates of the test substance were used.
Test results:
72 hour - EbL50>100 mg·L-1 (loading rate)
72 hour - ErL50>100 mg·L-1 (loading rate)
72 hour - NOELRb= 100 mg·L-1 (loading rate)
72 hour - NOELRr = 100 mg·L-1 (loading rate)
Classification of the test substance on the basis of hazard to aquatic environment was performed according to the Directive 93/21/EEC, Annex IV (article 5.2.1.).
According to the classification criteria given in quoted Directive the test substance, Ashes (residues) - Biomass Combustion, is not assigned to any of quoted toxicity categories.
