Millions of people worldwide die from air pollution every year. Because of the intensification of air pollution in urban centers, it poses a great risk-especially for people with various health problems [1-8]. Heavy metals hold a special place among the components of the air pollution. They cannot be destroyed or degraded in nature. They also tend to bioaccumulate in organisms. Thus, determining heavy metal concentration is of paramount importance for the identification of risk areas and levels [9]. A great volume of research has proven the significant effects of atmospheric heavy metal pollution on human health. A recent study has revealed that in 1952, 4,000 people died from heavy metal-induced damage to respiratory systems and reported high levels of heavy metals in their lungs, including Pb, Zn, and Fe [10].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
