Assessment of Nicotine Degradation in Cigarette Smoke under Different Storage Conditions (Light and Duration)

Nicotine, the primary component of cigarette smoke, is not only addictive but also indirectly contributes to lung diseases by increasing heart rate and blood pressure upon inhalation. Therefore, managing nicotine content in cigarette smoke necessitates accurate quantitative analysis. Nicotine from c...

Description
Summary:Nicotine, the primary component of cigarette smoke, is not only addictive but also indirectly contributes to lung diseases by increasing heart rate and blood pressure upon inhalation. Therefore, managing nicotine content in cigarette smoke necessitates accurate quantitative analysis. Nicotine from cigarette smoke is collected using a Cambridge filter, subjected to solvent extraction, and analyzed using instrumental techniques. However, since nicotine is susceptible to light-induced oxidation, losses may occur during pretreatment, reducing result reliability. This study assesses nicotine loss under various lighting conditions and storage durations. Nicotine collected in Cambridge filters is exposed to dark, visible radiation, and UV radiation (254 nm) for different time intervals (0–48 h), and the nicotine content is analyzed and compared. In dark conditions, a 1.6% decline in nicotine concentration occurs after 48 h. With visible radiation, a 9% reduction is observed, while under UV exposure, the concentration decreases by 16.9%. The UV radiation-associated decrease in nicotine concentration is −0.335% h−1, exhibiting strong linearity (R2=0.9465). Consequently, significant nicotine loss in Cambridge filter-collected samples is influenced by storage duration and lighting conditions. This study’s findings can enhance the accuracy of nicotine quantification in cigarette smoke, thereby improving the understanding of nicotine’s harmful effects in cigarette smoke.
