Volatile Emissions of Cigar Smoke and Their Predicted Impact on Indoor Air Quality

This study characterized emissions from cigars. This study adhered to the smoking test guidelines established by the International Organization for Standardization, and experimental tests were conducted on cigars under controlled conditions. The focus of these tests was the analysis of 20 volatile organic compounds (VOCs) in mainstream smoke. The results obtained demonstrate that cigar smoke contains not only aldehydes and a variety of VOCs, but also aromatic compounds (e.g. phenols) and a range of known or potentially harmful substances. In comparison with conventional cigarettes, cigars generally release levels of VOCs that are 1 to 2 orders of magnitude higher. Furthermore, the study investigated the potential impact of cigars on indoor concentrations of formaldehyde and other pollutants commonly encountered in domestic and public environments. This comprehensive data set provides a valuable reference point for evaluating public health risks and establishing indoor air quality standards.
