Air Quality in Flanders worse thanexpected13/01/2018
• No direct link with used AQ standards
• Some social groups do not participate
61
Intro - Particulate matter – AIRbezen – Results – AIRbezen+ - Conclusions
• Citizens are really concerned
• Motorised traffic: pollution
• Clear decrease traffic-related air pollution with distance
• Depends on local situation
• much larger variation than observed by classsic airmonitoring stations → need for measuring specificcomponents and toxicity
• Need for basic data: traffic
62
Intro - Particulate matter – AIRbezen – Results – AIRbezen+ - Conclusions
• Easy
• Win-win + emotion
• Communication (pre / during / post)
• Citizens realised unique sampling campaign
• Enormous awareness rising
• Enormous impact on society and policy-makers
• Citizens can provide meaningful data
• Subjective data seems to be meaningful
63
Intro - Particulate matter – AIRbezen – Results – AIRbezen+ - Conclusions
• Very intense time investment: post
• Financial support
• BAT
