Description of key information
Key value for chemical safety assessment
Additional information
According to column 2 of EC 1970/2006 Annex IX long-term toxicity testing shall only be proposed if the chemical safety assessment indicates the need to investigate further the effects on aquatic organisms.
For ashes (residues), coal one study was conducted to fulfill the requirements of the Association Française de Normalisation AFNOR. No guideline was indicated but in principle, the test conducted is similar to the OECD TG 212 (adopted 1998), however a clearly defined concentration range allowing the determination of a NOEC was not indicated.
In particular survival rate, growth rate and mobility of the larvae were evaluated as parameters indicative of toxicity.
Fertilized eggs from Cyprinus carpio were incubated for 7 days in test solutions at different dilution levels (undiluted, diluted to 1/4, 1/16 and 1/64) obtained from effluents from the storage tank for ashes of the thermic power plant in Montereau an inconspicuous water area used for dilution of effluents and leachates (87.5 g/L first series and 100 g/L second series) of treated ashes, either by Seine-water or by synthetic water.
There were no effects on survival of fertilized eggs by effluents from the storage tank of a thermic plant unit and by diluted effluents from an inconspicuous water area. The only slight effects on egg survival could be observed with undiluted leachates (again no effects at 1/4 dilution of the leachates). There were no effects on the mobility of newly hatched larvae (NOEC (7d) = effluent of storage tank or diluted effluent or 1/4 leachate of 100 g ash per 1 L water). There were also no effects on embryonal growth with 1/4 effluent from storage tanks, with 1/4 of the diluted effluent and with 1/4 of the leachate.
A definitive NOEC can not be derived because a clear concentration range is missing, however based on short-term tests from each trophic levels, the test substance can be regarded as acutely not harmful to aquatic organisms. Moreover, chronic studies for invertebrates and algae result in no classification; therefore and for animal welfare no further long term studies with fish are necessary.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
