|Characterisation Method Name:|
|NH3 impact on nuisance|
|Principal Method Name:|
|EPS: equivalency method using PM10 as a reference|
The characterisation factor is determined by an equivalency method using PM10 as a reference.
The same equivalency factor is used as in "NH3 impact on severe morbidity", i.e. 2.00 kg ‘effective’ PM10/kg NH3.
Calculation of characterisation factor
According to "PM10 impact on nuisance" there are 2.28E-03 person-years of nuisance per kg PM10. This will give 2.00*2.28E-03 = 4.56E-03 person-years per kg NH3.

|The system is global and the time period is 1990. The system borders are wide enough to contain all of the modelled impact quantity (visibility degradation). The response time for the environmental system is in the order of days to weeks. The area affected by a local emission is mainly within 1000 km.|
