Characterisation Method Information
Characterisation Method Name:
PAC impact on severe morbidity
Date Completed:
Principal Method Name:
EPS: cancer pathway
Method Description:

The characterisation factor is determined by the empirical method.

Category indicator value in system considered

The portion of cancer incidences not causing death (36%) is classified as severe morbidity. The average length of the morbidity is not known at present, but is assumed to be 5 years. This means that the total indicator value in the environmental system is (5/10)*(0.36/0.64)* 8.52E+06 = 2.40E+06 person-years of severe morbidity, where 8.52E+06 was the indicator value determined in "Arsenic air emissions impact on YOLL".

Contribution to category indicators value from a flow unit

The same contribution as in "PAC impact on YOLL" is valid, i.e. 6.67E-08 per kg PAC.

Calculation of characterisation factor

This would mean that the characterisation factor would be 2.40E+06 * 6.67E-08 = 0.160
person-years/kg PAC.

Methodological Range:
The system is global and the year is 1990. Most of the exposure occurs in urban areas why the characterisation modelling is focused on urban areas.
