Conclusion on classification

Environmental classification and labelling of a substance is generally based on data from short-term aquatic toxicity results, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient, Kow). Available adequate chronic toxicity data is also relevant for the assessment of long-term aquatic hazards (Regulation 286/2011/EC).


Short-term aquatic toxicity data is available for two trophic levels (daphnia and algae). The lowest short-term L(E)C50 was for daphnia with a 48-hour EC50 value of 32 mg/l. Chronic aquatic toxicity data is only available for algae; the 72-hour EC10 is 28.1 mg/L (based on growth rate). Limetol is not readily biodegradable and has a log Kow of 3.9.


Based on the above data, Limetol is classified as R52/53 according to Directive 67/548/EEC (DSD) and Aquatic Chronic 3 (H412) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
