Characterisation Method Information
Characterisation Method Name:
PM10 impact on morbidity
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: acute effects and global warming pathways
Method Description:
Model 1, acute effects

The characterisation factor is determined by an empirical method.

Category indicator value in system considered

ExternE (1995) estimate the exposure-response functions for ‘shortness in breath’ days for asthmatics to 0.14 per person-days per asthmatic per year per mg/m 3 . A rough
estimation of the number of asthmatics in the world is that 10% of the OECD (Organisation for Economic Co-operation and Development) population of 1.2 billion is asthmatics and none outside OECD. This gives 0.1*1.2E+09 *0.14/365*30 = 1.38E+06 person-years of morbidity, where 30 mg/m 3 is the estimated average PM10 concentration in the OECD countries (see "PM10 impact on YOLL").

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 pathway specific characterisation factor

1.38E+06 *2/3E-11 = 9.20E-06 person-years/kg PM10.

Model 2, global warming pathway

The characterisation factor is determined by an equivalency method using CO2 as a
reference.

Equivalency factor

The GWP for PM10 was determined to – 8.54 in section "PM10 impact on YOLL"

Calculation of pathway specific characterisation factor

The characterisation factor for CO2 with respect to morbidity was determined to 6.55E–07 person-years/kg CO2. Thus we obtain the characterisation factor for PM10 to –8.54*6.55E–07 = - 5.59E-06 person-years/ kg PM10.

Calculation of characterisation factor

The characterisation factor for both pathways is thus 9.20E-06 – 5.59E-06 = 3.61E-06 person-years/ kg PM10.
