inherently biodegradable

Additional information

Acid Black 210 biodegradation was estimated with the prediction tool (QSAR dyes R&C report produced by version QSAR dyes RC 2.0 Developed by Milano Chemometrics and QASR research group Dept. Earth and Environmental Science, University Milano Bicocca, Italy). The substance resulted as non ready biodegradable.

Moreover, Acid Black 210 potassium salt was tested following OECD 302B with a final result of 38% of biodegrdation after 28 days. The substance is then considered not readily biodegradable, but can be considered  inherently primary biodegradable.
