Description of key information

Additional information

The distribution in a sewage treatment plant (STP) has been estimated using the SimpleTreat model (implemented in EUSES 2.1.2), see table below.

Table: Distribution modelling for STP

Fraction of emission directed to air by STP

Fraction of emission directed to water by STP

Fraction of emission directed to sludge by STP

Fraction of the emission degraded in STP

Vi4 -D4 is not expected to undergo any significant biodegradation, and is predicted to have very high Henry’s Law constant and high log Kow/log Koc. Therefore, air and sludge are the main compartments to which it is expected to partition in a sewage treatment plant, with partition to water also being significant.
