“…The ash and unburned tobacco may also adsorb chemicals emitted during smoking . Overall, a wide range of chemicals in cigarette smoke has been detected in cigarette butts, while these chemicals may cause various adverse health effects including lung cancer, lower respiratory illness and impaired lung function in children, stroke, and heart disease . The presence of these chemicals in cigarette butts and the long length of time of cigarette butts existing in potential exposure environments indicate that cigarette butts may extend the time period over which cigarettes may pose a risk to humans and wildlife .…”

This study examined airborne emissions from cigarette butts for styrene, 2‐methyl‐2‐cyclopenten‐1‐one, naphthalene, triacetin, and nicotine. Ten experiments were conducted by placing butts in a stainless steel chamber and measuring the chemical concentrations in chamber air. Emission rates were determined from the concentrations. Triacetin and nicotine concentrations were roughly 50% of initial concentrations after 100 hours, while concentrations of other chemicals decayed to less than 10% of initial concentrations within 24 hours. Initial emission rates per cigarette butt ranged from 200 to 3500 ng h−1. Triacetin and nicotine emission rates at 25°C were 1.6 to 2.2 times higher than the rates at 20°C, while the emission rates of other chemicals at 25°C were 1.1 to 1.3 times higher than the rates at 20°C only during the first sampling period. The chemical concentrations and emission rates at 30°C were comparable or lower than the values at 25°C, possibly due to different batches of cigarettes used. The 24‐hours emitted mass of nicotine from a cigarette butt at 25°C could be up to 14% of the literature reported nicotine masses emitted from a burning cigarette.
