15 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E Approach to assessment of integral pollution by PM Individual pollutants have different toxicity… We need to find a quantitative criterion, which has property of additivity… An approach based on idea of “threshold concentration level” is widely used

16 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E Quantitative additive criterion: A portion of an air volume, which could become unsuitable for humans because of presence of a given pollutant in air. Let us call this portion “Hazard Quotient” (HQ): HQ = C / T, where  C – airborne concentration of a given pollutant;  T - permissible threshold concentration for a given pollutant.

17 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E An example: Cadmium within particulate matter could make 10% of an air volume unsuitable for human 1 cubic meter Cd – 10% clean air

18 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E An example: B[a]P within particulate matter could make 15% of an air volume unsuitable for human 1 cubic meter B[a]P – 15% clean air Cd – 10%

19 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E An example: Particulate matter itself could make 20% of an air volume unsuitable for human 1 cubic meter PM – 20% clean air B[a]P – 15% Cd – 10%

20 EG on Particulate Matter, Berlin, May 2005 EMEP/MSC-E Integral PM pollution  ( HQ i ) = Hazard Index for PM (dimensionless) HI =  (HQ i ) = cubic meter PM – 20% clean air B[a]P – 15% Cd – 10%

21 EG on Particulate Matter, Berlin, May 2005 Integral Pollution by Particulate Matter (Hazard Index) C ij – mass concentration of the i-the pollutant within the j-th pollutant class; φ ij – share of the concentration in particulate phase… T ij - permissible threshold concentration… COV j – coverage coefficient for the j-th pollutant class.
