Additional information

The test on ready biodegradability of SymHelios 1031 in water (Simon_2007) performed according to OECD 301F and GLP was rated with RL=1 (reliable without restrictions) and used as a key study. The results of this screening test indicted that SymHelios 1031 is not readily biodegradable. The degradation rate of the test substance is 2.7% (ThOD) in 28 days with 100 mg/L test substance, 4.9% (ThOD) in 28 days with 25 mg/L test substance. No inhibitory effects of the test item were observed (more than 25 % degradation occurred within 14 days) in the toxicity control. No abiotic degradation could be observed during test.
