^a) These exposure response functions are all expressed per 1 unit of exposure.
^b) Different types of calculation methods were applied (see also paragraph 2.1):

1A: Deriving the PAF from epidemiological data; applying the PAF to total burden of disease data (WHO database)

2A: Indirectly calculating the PAF from the Unit Risk and background incidence; applying the PAF to total burden of disease data (WHO database)

2B: Using a Unit Risk to calculate Attributable Incidence; calculating the Burden of Disease: AI x DW x L

^c) The RR for spousal smoking is used as a proxy for any regular exposure (including at work).
^d) For lead, a shift in exposure distributions is linked to a unit risk approach. Further information provided in 3.6.

Function: No point estimate can be given, as the exposure response function is given by a more complex function.
AI = Attributable Incidence;
ARI = Acute respiratory infections;
Bq = Becquerel;
IHD = Ischemic heart disease;
Lday16h = noise level for day and evening;
LRS = Lower respiratory Symptoms;
PCB = Polychlorinated biphenyls,
PAF = Population Attributable Fraction;
PM = Particulate Matter;
RAD = Restricted activity days;
SHS = Second-Hand Smoke,
SOMO35 = sum of maximum 8-hour ozone levels over 35 ppb (70 µg/m3);
UR = Unit Risk;
RR = Relative Risk;
yr = year; µg = microgram; mg = milligram; pg = picogram; kg = kilogram; d = day
