Insinuation of Toxic Metal on Smokers’ Lungs

Heavy metals are major cause of environmental pollution and due to their toxicity, they persist long in atmosphere. Toxic metals or heavy metals have ability to accumulate in human body and cause various respiratory disorders. Heavy metals sometimes become highly toxic by reacting with different environmental elements. Tobacco smoking is one of the major concerns for the accumulation of toxic metals in smokers’ lungs and people residing with smokers (known as passive smokers) also being affected, especially children. ETS (environmental tobacco smoke) represents inhaling of tobacco and release heavy metals in ambient air involuntary. The development of children pulmonary function severely gets affected due to passive smoking. Every year millions of people die because of tobacco. Heavy metal content is present in the lung tissue of smoker and non-smokers, and which get mixed with the blood at time of gasses exchange in alveoli and circulate in the body. Therefore, tobacco smoking is considered one of the serious global health concern due to its carcinogenic effects on human body. This majorly happens because of the presence of toxic metals like Arsenic (As), Cadmium (Cd), Mercury (Hg), Lead (Pb), Chromium (Cr). The concentration of both Pb and Cd, are potent human carcinogen. This study presents important information regarding effect of heavy metals inhaled content in tobacco and its transference to cigarette smoke and their accumulation in smokers’ lung tissue.
