Description of key information

The test substance, Ashes (residues) - Biomass Combustion, was tested in acute immobilisation test on Daphnia magna.
The test was performed according to method C.2 – Daphnia sp. Acute Immobilisation Test, Council Regulation (EC) No. 440/2008, published in O.J.L 142, 2008.

Key value for chemical safety assessment

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-1wereanalysed in the limit test. For all evaluations and results the loading rates of the test substance were used.

Test results:

24 hour–EL50>100 mg·L-1       (loading rate)

48 hour–EL50>100 mg·L-1       (loading rate)

24 hour–NOELR=100mg·L-1       (loading rate)

48 hour–NOELR=75mg·L-1       (loading rate)

24 hour–EL100>100 mg·L-1       (loading rate)

48 hour–EL100>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.
