Mackay fugacity modelling (level 3)
indicates that, taking into account
degradation and using inflow
parameters which are consistent with
the known production tonnage of this
substance in, fugacity coefficient
indicates that environmental
concentrations in water are
predicted to be 8.49e-028 (atm), in
air (atm) 2.99e-026 and soil
3.73e-026 (atm) and sediment to
be 7.69e-028 (atm).
These are negligible low levels.
This can be considered a worse case
prediction as it assumes all product
is emitted with no emission control
