Description of key information

Additional information

The distribution in a sewage treatment plant (STP) has been estimated using the SimpleTreat model (implemented in Chesar 3.7/EUSES 2.1.2), see table below. The distribution calculation is done for the substance using the physicochemical and biodegradation properties of the substance.

Table: Distribution modelling for STP

Fraction of emission directed to water by STP

4.888

[%]

Fraction of emission directed to air by STP

92.91

[%]

Fraction of emission directed to sludge by STP

2.196

[%]

Fraction of the emission degraded in STP

0

[%]

The distribution modelling indicates that tetramethylsilane will partition mostly to air.
