Description of key information
Additional information
Additionally to the presented screening tests in water showing no or little degradation of the test substances under test conditions, several publications on biodegradation processes in the environment or by other organisms have been available.
Wu et al. have reported on readily degradation of Benzotriazoles by Fenton reaction in presence of peroxide and iron. In addition, white rot fungi Phanerochaete chrysosporium has shown in experiments effectively degradation of the test substances under several conditons. Fungi have been cultivated for three days at 39 °C and afterwards exposed to concentrations up to 0.2 mg/mL Benzotriazole. In a second experiment, a mixture of Benzotriazole and Tolyltriazole was used. Only in test series with low concentrations (0.05 mg/mL) of Tolyltriazole merely no degradation has been observed. Furthermore, tests with horseradish plants were conducted showing that these plants also can remove Benzotriazoles from the soil. In the experiments adverse effects on the growth of the plants have been observed. Nevertheless, sampling of soils after three month has shown reduced concentrations of Benzotriazole of about 95%. An additional experiment with ground horseradish roots with and without addition of peroxide has shown a DT50 of two days at room temperature for Benzotriazole (Wu et al., 1998).
