Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Conclusion on classification

Reliable results from short- and long-term toxicity studies of three trophic levels (fish, invertebrates, and algae) are available.

 

·     Biodegradation in water: not readily biodegradable

·     Bioaccumulation: BCF 17

·     Log kow: < 4 (2.53)

·     Lowest short – term value: EC50 17 mg/L (daphnia; three trophic levels)

·     Lowest Chronic value: NOEC 5.76 mg/L (fish; three trophic levels)

Acute (short-term) aquatic hazard:

Not necessary, lowest short-term value is > 1 mg/L therefore classification is not required.

 

Long-term (chronic) aquatic hazard

Based on available data set - not necessary, as the substance is non-rapidly degradable substances and there are adequate chronic toxicity data available. Chronic data are available for TCE from three trophic levels (fish, invertebrates and algae). From chronic data set fish was identified as most sensitive species with a NOEC of 5.76 mg/L.The value is clearly above the cut-off value of ≤ 1 mg/l relevant for classification long-term based on available chronic data.

 

However, according to Harmonised classification outlined in Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation) TCE has to be classified for environmental toxicity: 

 

Legal binding classification for TCE:

Aquatic Chronic 3 (labelling: H412)
