Additional information

Studies with fish, daphnids and algae as well as with aquatic microorganisms are available and thus, the PNECs are based on the test results and assessment factors recommended in the Technical Guidance Document (ECHA, 2008) have been applied. For the compartments sediment and soil, no studies have been conducted and the PNECs have been calculated using the Equilibrium Partitioning Method as screening values. The outcome of the Chemical Safety Assessment indicates no need for testing on sediment or soil dwelling organisms as the PEC/PNEC ratios does not exceed the trigger value of 1. Additionally, triallyl cyanurate has only low adsorbing potential and a study with sediment dwellers is not triggered.

The PNEC oral is derived from a toxicological endpoint as the toxicity towards birds has not been tested.

Conclusion on classification

Fish was found to be the most sensitive aquatic species. The LC50 (96 h) is 7.05 mg/L and the substance is not readily biodegradable thus, triallyl cyanurate is classified according to EU classification as R51/53 and according to GHS as chronic category 2.
