Description of key information
Additional information
The photolytical dissipation half-life of beta-analine according to the reaction with OH radicals was estimated to be approximately 12 hours. Therefore this reaction is expected to be the primary degradation mechanism for this substance in air and the estimated half-life indicates a low level of concern for persistence of beta-alanine in air. Beta-Alanine is considered readily biodegradable based on the results of an OECD test (301 C) under GLP conditions. The degradation after 14 days was 87% related to BOD. Based on the experimental log Kow of -3.05 the substance has no bioaccumulation potential. This assumption is confirmed by a calculated BCF of 0.5. A low sorption potential to soil organic matter can be assumed due to a calculated Koc value of 0.02798 L/kg (based on log Kow) for beta-alanine. The calculated Henrys Law Constant of 0.00000758 Pa-m3/mole indicates a low potential for volatilization from surface waters for this substance. According to the Mackay Fugacity Model Level I, the main target compartment of the environmental distribution of beta-alanine in a "unit world" is water with 100%.
