RESUMO
Indoor go-kart driving and viewing is enjoyed by people of all ages. However, it may pose health hazards, especially for children, pregnant women, cardiovascular patients, and elderly individuals. Depending on the race length, for example, high concentrations of various contaminants may result in severe health problems. Therefore, this project investigated the Indoor Air Quality of eight indoor go-kart facilities. In general, karts that used regular fuel produced the highest concentrations of CO, benzene, TVOC, and BaP, with maximum levels up to 150 mg/m3 , 170 µg/m3 , 2690 µg/m3 , and 8.7 ng/m3 , respectively. As expected, the maximum CO concentrations at go-kart facilities that used liquid gas and electric karts (20 and <6 mg/m3 , respectively) were significantly lower than those at other facilities. The highest 95th percentile values for NO (2680 µg/m3 ) and NO2 (280 µg/m3 ) were measured for karts with liquid gas. The alkane, alkene, and cycloalkane groups, as well as benzene and the alkyl benzenes, were the predominant components of the measured TVOCs. Overall, owners of indoor go-kart tracks should ensure that the ventilation with regard to combustion products is optimally adapted in any case to reduce the levels of critical air pollutants.
