Key value for chemical safety assessment

LC50 for freshwater fish:
7.05 mg/L

Additional information

The short-term effect of triallyl cyanurate on fish was determined in a study conducted according to OECD Guideline 203 (1992) and Method C.1 of Commission Regulation (EC) No. 440/2008 (2008) and in compliance with GLP. As the LC50 (96 h) is within the range of 1 mg/L and 10 mg/L, the substance is considered to be toxic to aquatic organisms and has to be classified as H411.

A further study is available performed in accordance with the national standard method DIN 38 412 - L 20 (Evonik Degussa GmbH, 1984). The study lasted 48 h only and was thus shorter than the study duration recommended by today's standard methods. Furthermore, no analytical monitoring was performed and a LC50 was not reported which is the relevant endpoint of short-term studies with fish and therefore, the study is not considered in the hazard assessment for triallyl cyanurate.
