Additional information

Although the studies available do not follow current standard guidelines, they are sufficient to demonstrate that toluene is readily biodegraded by both non-adapted and adapted sewage sludge inocula. Three of these studies were also used as part of a weight of evidence that toluene is readily biodegradable in the EU RAR for toluene (2003).

The available data indicate that toluene can be considered readily biodegradable. Therefore, based on the screening criteria for persistence stipulated in ECHA’s Guidance on information requirements and chemical safety assessment - Part C: PBT Assessment (2008) toluene is not considered to be persistent (P) or very persistent (vP).
