Characterisation Method Information
Characterisation Method Name:
SO2 impact on wood
Date Completed:
Principal Method Name:
EPS: secondary aerosol pathway
Method Description:
Model for secondary aerosol pathway

The characterisation factor is determined by an equivalency method using PM10 as a reference.

Equivalency factor

The same equivalency factor is used as in "SO2 impact on severe morbidity", i.e. 2.83 kg ‘effective’ PM10/kg SO2.

Calculation of characterisation factor

According to "PM10 impact on wood" there are 0.00991 kg wood per kg PM10. This will give 2.83*0.00991 = 0.0281 kg wood per kg SO2.
