|Characterisation Method Name:|
|PAC impact on severe morbidity|
|Principal Method Name:|
|EPS: cancer pathway|
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 8.52·E+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 2.40·E+06 * 6.67E-08 = 0.160

|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.|
