摘要

There is limited information regarding organochlorine pesticides (OCPs) residues in tobacco products found in the Iranian market, especially in various types of waterpipe tobacco. The purpose of this research was to evaluate the concentration of OCPs in various waterpipe tobacco—both fruit-flavored and regular—and compare it with cigarette tobacco. Additionally, by analyzing the OCPs levels in fresh tobacco compared to tobacco wastes, an estimate has been made for the quantity of pesticides released into smoke during consumption. Our results indicated that the average detection frequency (DF) of pesticide residues was 46% for fruit-flavored tobacco, 82% for regular tobacco, and 42% for cigarette tobacco. Hexachlorocyclohexane (HCHs) isomers were the predominant pesticides in all three types of tobacco with the mean of 43.11 ± 31.81, 89.63 ± 56.08, and 41.65 ± 35.37 ng/g for fruit-flavored tobacco, regular tobacco, and cigarette tobaccos, respectively. Both the levels and DF of pesticides in post-consumption wastes were significantly reduced compared to that in fresh tobacco (p < 0.05). For all tobacco types—fruit-flavored, regular, and cigarette—notable OCPs residues were released into the gas phase, with cigarette tobacco having the highest rate at approximately ~ 37% because of greater combustion temperatures. The research points out some limitations, particularly the disregard for bowl water and charcoal as elements of waterpipe waste, which could lead to an overestimation of pesticide levels in inhaled smoke. Further studies are needed on the environmental impact of tobacco wastes and promoting for better waste management practices as well as public awareness.
