Description of key information

No studies on sediment toxicity are available for propylene glycol butyl ether.

Key value for chemical safety assessment

Additional information

The test substance is not supposed to be directly applied to sediment and an indirect exposure to sediment in unlikely since the substance is readily biodegradable. Therefore, taking into account the favourable aquatic toxicity data (no classification), the low potential for adsorption to sediment, the readily biodegradability and the estimated PEC/PNEC ratio being clearly <1, no long-term toxicity testing for sediment organisms is proposed.
