Particulate Matter Concentrations during the XXIX Summer Olympic Games in Beijing
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 2008. Continuous measurements were performed by a fast responding nephelopmeter DustTrak. Temperature and relative humidity were monitored simultaneously with the aerosol measurements. The locality of measurements was in the Olympic Village. The average concentration of PM10 during the whole monitoring period was measurement was 177.4 g·m-3 (±151.5), median 151.5 g·m-3). Maximum concentrations reached 660 g·m-3, minimum concentrations were as low as 10 g·m-3. 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. This fact can be documented by decreased ambient temperature, changes in relative humidity and increased frequency of rain. The results of measurements are discussed in terms of the possible effects on the elite athlete’s health and efficiency of restrictive measures taken by the Beijing municipal administration.
