Air and noise pollution are environmental pollutants that have been linked to several health diseases. Motorcar racing are leisure sporting activities attended worldwide. Traffic noise and air pollution have been observed to have an adverse effect on human populations, but there has not been any published information on motor car racing exposure for spectators. In the present study, ten racing events were sampled for PM_2.5 and noise pollution. Sampling was conducted from May to October 2017 using two Dylos DC1700 monitors, a TSI instrument AM520 Sidepak, and a Digisense portable sound meter. Side-by-side sampling was conducted to validate the Dylos instruments with the TSI AM520 Sidepak instrument. A moderate positive log-log relationship existed between the Dylos instrument and the Sidepak instrument (R² = 0.4). The Sidepak instrument was used to estimate hazard levels at the race tracks from PM_2.5. Based on the calculations, the 24-hour time-weighted average mean concentration ranged between 15µg/m³ and 33µg/m³. These results correspond to the moderate category in the EPA Air Quality Index (AQI), suggesting that unusually sensitive populations could show respiratory symptoms. Also, older adults with respiratory problems are at risk. Further recommendations for the study include gravimetric analyses of the Sidepak with a Federal Reference Method and more detailed assessment of particle composition.
