Chemical compound (FA) and acetaldehyde (AA) are the two most plentiful aldehydes in the atmosphere and are considered basic and/or secondary contaminants. This chapter aims to decide the concentrations of FA and AA in the ambient air of five Smoke Stations (GS) in the city of Salvador, Bahia, Brazil. The study used three passive fancy stitching exposed together for 8 h and analysis by extreme-performance liquid chromatography-ultraviolet discovery (HPLC-UV). The concentration ranges found were 3.31 - 5.78 μg m-3 for FA and 10.5 - 28.2 μg m-3 for AA. Even though these values were inferior the exposure limits urged by national and worldwide agencies for occupational atmospheres, FA concentrations were higher than the tighter limit (3.30 μg m-3) set by the Texas Material Quality Commission - TCEQ for complete outdoor exposure. The life cancer risks (LCR) connected to GS employees' uncovering to these aldehydes over a 30-year ending ranged from 2.46x10-6 - 6.60x10-6 for AA and 4.51x10-6 - 8.00x10-6 for FA. These results demonstrate the need for occupational uncovering limits, particularly concerning FA, which is connected to nasopharyngeal cancer, as they exceed the acceptable level established apiece US Environmental Protection Instrumentality (1.0x10-6).
