Description of key information

Hydrocarbons, C9-C10, aromatics, >1% Naphthalene are a combination of Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics. Read across data is available for Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics and the worst case scenario for each end point has been presented.

Hydrocarbons, C9, aromatics, were inherently to readily biodegradable in an OECD 301B, 301D and OECD 301F Manometric Respirometry test. The OECD 301F test resulted in 78% biodegradation in 28 days using a predominantly domestic aerobic non-acclimated activated sewage sludge inoculum. The OECD 301B and 301D tests resulted in 56% and 21%, respectively.

 

Hydrocarbons, C10, aromatics, >1% naphthalene, biodegraded 58% after 28 days in an aerobic OECD 301F test, and under the conditions of the study was inherently biodegradable.

 

This data is used for read across to Hydrocarbons, C9-C10, aromatics, >1% Naphthalene.
