1 Lower limit estimate from Wilton (2001).
2 From Wilton (2002).
3 From Fisher et al (2002) based on a 4.3% increase in mortality, in population over 30, per 10 µgm-3 increase in annual average PM2.5 concentrations above 7.5 µgm-3.
4 Rupendra Shresthra from Fisher et al (2002) analysis based on a 4.3% increase in mortality, in population over 30, per 10 µgm-3 increase in annual average PM2.5 concentrations above 7.5 µgm-3.
