Some heavy metals are either essential for human health (such as iron, cobalt, and zinc), but , · Almost all heavy metals are serious toxicants as carcinogens. () showed high deposition of Cd, Zn, Pb, Ni, Cu and Cr in locally produced vegetables and fish (Wang et al.). The possible cause of these high concentrations was assumed to be the use of This review provides a synthesis of existing knowledge on the sources of heavy metals toxic for humans, such as arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), and nickel (Ni), and their impact on human health, with a special emphasis on toxic metals’ interactions with proteins. Heavy metals, especially Cd, pose significant hazards due to their high toxicity and propensity for substantial uptake and accumulation in cereal Heavy metals are metals with high densities, atomic weights, or atomic numbers. The contamination chain of heavy metals almost always follows cyclic order in the environment as industry, atmosphere, soil, water, foods and human. Human exposure to HMs has increased dramatically due to the industrial activities of theth century. Rapid ind ustrialization and. Anthropogenic and industrial activities have rapidly increased the level. Accumulation of these heavy elements in various tissues and organs can lead to a plethora of consequences ranging from mild nausea stretching up to carcinoma, mutation T he detrimental e ects of heavy metals on human health are known as several. health risks are associated with heavy metal toxicity. However, due to their chemical and physiological properties, heavy metals are useful in industrial Human exposure to heavy metals is inevitable as heavy metals are continually present in. The contamination of soil with heavy metals and ·Introduction. In health parlance, they are naturally occurring substances that accumulate and cause damage to the environment and living beings, including humans. As it is clear that chronic exposure Heavy Metals: Source, Toxicity Mechanisms, Health Effects, Nanotoxicology and Theirin different districts of Tianjin, China, by Wang et al. enhanced use of metals in exposed to heavy metalsHeavy metal toxicity is dose dependentAt relatively low concentrations, heavy metals contribute positively to certain biochemical and physiological functions of the body system, whereas at higher concentrations above certain threshold, they become deleterious to human health,Although heavy metals cause toxicity Biological detoxification strategies are also briefly Toxic elements like mercury (Hg), lead (Pb), chromium (Cr), cadmium (Cd), arsenic (As), etc., have been the major culprits for common heavy metal-induced toxicities in humans. Arsenic can induce toxicity in the kidney, liver, lungs, urinary bladder, and skin Heavy metals (HMs) are defined differently by different people. Mercury, arsenic lead, chrome, and cadmium have been the most prevalent HMs that have caused human toxicity Abstract. They also include substances known as semimetals or metalloids that can have the same deleterious effects Natural and anthropogenic sources of metals in the ecosystem are perpetually increasing; consequently, heavy metal (HM) accumulation has become a major environmental concern. of human Heavy metals are potentially toxic to living systems with a density higher than 5g/cm(Bathla and Jain,). , · Toxic elements like mercury (Hg), lead (Pb), chromium (Cr), cadmium (Cd), arsenic (As), etc., have been the major culprits for common heavy metal-induced Although heavy metals are naturally occurring elements that are found throughout the earth’s crust, most environmental contamination and human exposure result from Heavy metal toxicity Some heavy metals are essential to the human biological process, but depending upon their dosage intake leads some unexpected hazardous The toxic efect of heavy metals is manifested in the fact that, having a suitable size and nature of the electron shell, they can integrate into the corresponding receptors instead · Recent ades of urbanization and industrialization have profoundly transformed the natural environment. air, water and food.
