Description of key information

A soil micro-organisms toxicity study is not required as DEE does not bioaccumulate, is very volatile and therefore does not remain in sediment or soil over a longer period.

Key value for chemical safety assessment

Additional information

A study on soil micro-organisms is not proposed by the registrant as the chemical assessment does not indicate a need to investigate further effects on soil organisms. This is based on the knowledge that the substance has a low bioaccumulation potential and as outlined in the section on environmental fate, the substance due to its low water solubility and high vapour pressure will volatilise rather quickly from the aqueous environment or soil and becomes abiotically degraded in air very quickly (half-life < 1day). Hence, significant exposure of sediments and soil is not of concern.
