Hazard for predators

Secondary poisoning

Hazard assessment conclusion:
no potential for bioaccumulation

Additional information

Based on the limited potential for exposure and bioaccumulation, and observed metabolism in both mammals and fish, secondary poisoning is unlikely to be an issue for the notified substance.

Conclusion on classification

According to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 the substance is not classified as an Acute Category 1. Acute toxicity values for the three trophic levels are all greater than the reported water solubility of the substance thereby indicating that the substance is not classified for acute aquatic effects.

 

According to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 the substance is not classified for long-term aquatic toxicity based on the test substance and read-across data from 6:2 FTOH. Given the rapid conversion of the test substance to 6:2 FTOH, the latter is the more relevant substance to study. Therefore, the chronic algal endpoint for the test substance and the chronic 28-day carp and 21-day daphnid studies for 6:2 FTOH were considered for the chronic classification.

 

According to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 the test substance is not hazardous to the ozone layer. There are no indications that global warming, ozone depletion in the stratosphere, ozone formation in the troposphere or acidification effects will occur based on the substance structure and estimated half-life in air of approximately 6 hours.
