The objective of this work was to perform the environmental monitoring, including the evaluation of ambient temperature, relative humidity, noise and quality of the air, of indoor and outdoor kart racing circuits, located at the city of Rio de Janeiro. The quality of the air was monitored by the determination of the texts of benzene, toluene, ethylbenzene e xylenes, known as BTEX. These compounds have high toxicity and, if found above the permitted limits, they can jeopardize the health of the customers and company's employees, in special. For the quantification of BTEX in the air, the active sampling technique was used, followed by the extraction with solvent and analysis by Gas Chromatography with mass spectrometry detection. The level of noise parameter was also studied and compared to the current legislation. It is known that the exposure to high levels of noise jeopardizes the audition, especially in a long term, and in some cases (generally occupational) can cause its total or partial loss. The equipment used for the measurement was a decibilimeter. The results of the indoor and outdoor kart racing circuits and the parking lot without any kart activity were analyzed and compared to each other
