Characterisation Method Information
Characterisation Method Name:
PM10 impact on nuisance
Date Completed:
Principal Method Name:
EPS: "restricted activity days" and "symptom days" pathway
Method Description:

The characterisation factor is determined by an empirical method.

Category indicator value in system considered

ExternE (1995) use data from Ostro et al and Krupnick et al. on exposure-response
functions for ‘restricted activity days’ and ‘symptom days’ of 49.9E-03 and 465E-03 per person per year per mg/m 3 respectively. This will result in 0.515/365*46*5.28E+09 =
3.43E+08 person-years.

Contribution to category indicators value from a flow unit

The same contribution apply as for model 1 in section "PM10 impact on YOLL", i.e. 2/3E-11 per kg of PM10.

Calculation of characterisation factor

3.43E+08 *2/3E-11 = 2.28E-03 person-years/kg PM10

Methodological Range:
For reasons mentioned in 9.1.3 global system borders are chosen. The time period investigated is the year 1990
