Discussion 2: Results PM10
Results depending on:•Type of monitoring equipment•Season•Site•Wind direction
Result:
Correctionfactor

Methodological issues on
monitoring and modelling:
AIR4EU
WWW.AIR4EU.NL
Disc. 3: Accuracy and its consequences
Results close to limit value
Exceeding often due to correction factor
19
kaart
Discussion 4: What is desirable?
Local authorities pushing PM10 below limit value
Result: A lot of effort for small areas
Health authorities focussing on PM10 in general
Result: Effects on large areas
20
kaart
Discussion 5: What solution?
Large emissions
High stack
Result: Low concentration
Small emissions
Low stack
Result: High concentrations?
No EU Directive

Discussion 6: Concentration PM10
Due to local sources
