Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
No simulation tests in water and sediment are available for propylene glycol methyl ether acetate.
Key value for chemical safety assessment
Additional information
Propylene glycol methyl ether acetate is readily biodegradable in freshwater with a low potential for adsorption to sediment. Based on the distribution modeling (Level III fugacity model), most of the substance released directly to water will remain in the water compartment and is expected to be biodegraded. The risk assessment shows that the PEC/PNEC ratios for sediment are clearly < 1, indicating no need for further information or testing. According to REACH Annex IX requirements, sediment simulation testing shall only be considered for substances with a high potential for adsorption to sediment, hence a simulation test in water and sediment can be waived for propylene glycol methyl ether acetate.
