Cigarettes Contain Arsenic: A Study of Tobacco in New Delhi Region using AAS-VGA

Arsenic, a very toxic metalloid, presents significant health hazards from multiple environmental exposures, including the inhalation of arsenic-laden tobacco smoke.This pertains to the accumulation of arsenic in combustible tobacco product and the related health hazards for smokers and anyone exposed to second hand smoke.Inorganic arsenic, the predominant substance in tobacco, is converted into less harmful metabolites during smoking.Nonetheless, the methylation process in smokers is suboptimal, resulting in increased concentrations of harmful arsenic compounds in blood.Atomic Absorption Spectroscopy with a Vapor Generator Assembly (AAS-VGA) was used to determine arsenic content in tobacco product, owing to its superior sensitivity and cost-effectiveness.Prior to the analysis of concentration of As, the process entailed closed vessel digestion of tobacco samples using Microwave Digestion System (MDS-10).This research revealed elevated arsenic concentrations, yet no threshold for tobacco as such by WHO or any organization.This increases the risk of developing arsenic-related health issues, such as lung cancer, cardiovascular disease, and other chronic ailments, to both active and passive smokers.Smoking therefore also has the potential to make a significant contribution to total indoor air pollution.This study underscores the need for more stringent public health measures to diminish arsenic exposure from smokable tobacco, while promoting the implementation of advanced detection techniques such as AAS-VGA for efficient monitoring and reduction of contamination.
