- JUSTIFICATION FOR DATA WAIVING
In accordance with Annex X, section 9.4, column 2 of REACH Regulation, long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment according to Annex I indicates the need to investigate further the effects of the substance and/or degradation products on terrestrial organisms.
Based on the available environmental test data, the substance is not considered to have any adverse effects. Short term tests with several species are available (acute fish study, Klimisch 2; OECD TG 203; acute daphnia study, Klimisch 2, OECD TG 202; algae growth inhibition study, Klimisch 2, OECD TG 201). All tests were performed using either direct application of the test substance (acute fish study) or water accommodated fractions (acute daphnia and algae study). The following results were obtained in the short term toxicity studies:
LL50 (fish) > 1000 mg/L (nominal; precipitation observed)
EL50 (daphnia) ≥ 10000 mg/L (nominal)
EL50 (algae) > 1000 mg/L (nominal)
No abnormal effects were observed for fish, daphnia and algae at the highest tested loading. The algae test further resulted in an extrapolated EL10 of 41 mg/L. This value was plausible, because the inhibitory effect showed a relatively weak dose-response relationship, with no unequivocal dose response discernible from 100 to 400 mg/L.
Based on the above results the test substance does not need to be classified and labelled according to Regulation (EC) No. 1272/2008.
According to Regulation (EC) No 1907/2006 (REACH) Article 14(4), no additional steps on chemical safety assessment are needed, because the test substance does not fulfil the criteria for any of the hazard classes listed in part 4 (a) to (d). In conlusion, the chemical safety assessment showed no need to further investigate the long-term terrestrial toxicity.
Furthermore the test substance is composed of quartz (SiO2) and chalk (CaO). Both are natural constituents of different type of soils (e.g. sand) and can be found ubiquitous in nature. Observations show that environmental organisms show a high tolerance towards constituents of sand. Furthermore the substance is inorganic and bioaccumulation can be excluded due to the very low water solubility. Therefore a negative effect on environmental organisms can be excluded and a test is scientifically not justified.
