Characterisation Method Information
Characterisation Method Name:
Hg water emissions impact on NEX
Date Completed:
Principal Method Name:
EPS: equivalency method
Method Description:
NEX is Normalised EXtinction of species.

Due to the global mixing processes, the same characterisation is used as for emissions of
mercury to air "Hg air emissions impact on NEX", i.e. 1.20E-10 NEX/kg Hg.

Methodological Range:
The flow group is emissions of mercury to water anywhere in the world, but at amounts that do not cause local thresholds to be exceeded.
