Abstract
Particulate matter concentration of aerosol below 10 mm of aerodynamic diameter (PM10) was monitored during the XXIX Olympic Games in Beijing between 3 and 24 August 2009. Continuous measurements were performed by a fast responding nephelopmeter DustTrak.
Temperature and relative humidity were monitored simultaneously with the aerosol measurements. The concentrations were seemingly higher before the game started than during the event.
The possible explanation for this fact is that restrictions of emissions in the traffic and industrial sector were successful, however at the same time, the weather presumably contributed to decreased PM concentrations to a significant extent.
