Additional information

All calculated PNEC values are based on reliable studies according to the respective OECD guidelines. As no relevant data are available on the toxicity of CTC towards soil and sediment organisms and no significant exposure is anticipated from physico-chemical properties and present pattern of uses, no PNEC is derived for these compartments.

Conclusion on classification

Carbon tetrachloride is considered as not readily biodegradable and has no significant potential for bioaccumulation with low bioconcentration factors measured in aquatic species. Carbon tetrachloride is harmful to fish, daphnia and algae with acute EC50 in the range 10 -100 mg/L. Chronic toxicity data are available for the 3 trophic levels with NOEC > 1 mg/L.

On this basis, environmental classification for carbon tetrachloride is not required neither according to the Dangerous Substance Directive, nor according to the CLP 286/2011 Regulation.
