Biodegradation in water:
Prediction model based estimation and data from read across were used to estimate the biodegradation in water for the test compound Acid violet 43. The summary is as below:
Estimation Program Surface Interface (EPI Suite, 2016) was run to estimate the biodegradation potential of the test compound Acid violet 43 (CAS no 4430 -18 -6). The screening was performed using BIOWIN v4.10 software. The results indicate that Acid violet 43 is not expected to be readily biodegradable.
Short term aerobic biodegradation study (Pagga and Brown, 1986) was conducted for the test material Acid green 25 (RA CAS no 4403 -90 -1). Readily water-soluble dyestuff acid green 25 was subjected to modification of the OECD Guideline 302B of the static test method. 100 mg/L dyestuff was tested with 0.5 mg/L activated sludge for inherent biodegradtion for upto 42 days. The feeding used for inoculum was 100 mg/L yeast extract every week. Extinction at absorption maximum and DOC (dissolved organic carbon) were the parameters included in the study. The test compound Acid green 25 showed 29% DOC removal suggesting that the inherent biodegradation process is possible.
Based on the EPI suite estimate, the test compound is considered to be not biodegradable in water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
