Description of key information
DT50 = 14.8-15.8 days in buffer solution and 1.3-1.9 days in sterile natural water (OECD 116)
Photodegradation of triafamone in water contributes to the overall degradation process.
Key value for chemical safety assessment
Additional information
The photolytic degradation of triafamone (CAS No. 874795-61-6) in sterile aqueous buffer solution at pH 5 and in sterile natural water, was studied according to OECD guideline 316 under exposure to simulated sunlight with 1-1.2 mg/L test item and at a temperature of 24.3-25.3 °C. The experimental data were described by a single first order (SFO) kinetic model. The half-life (DT50) for triafamone in the irradiated samples was 14.8-15.8 days in buffer solution and 1.3-1.9 days in sterile natural water. Based on the experimental DT50 value of 14.8-15.8 days, the environmental DT50 value is calculated to be e.g. 50.7-55.3 solar summer days at Phoenix, Arizona, USA, or 107.6-117.4 solar summer days at Tokyo, Japan. In natural water the DT50 was considerably shorter with calculated environmental DT50 values of 12.6-14.2 solar summer days at Tokyo, Japan. The results show that photodegradation contributes to the degradation of triafamone in the aquatic environment.
