Abstract
Heavy metals are a group of elements that have high atomic weights and densities. Some examples include lead, mercury, cadmium, and arsenic. Due to the negative impacts that are produced all across the world, heavy metal environmental contamination is becoming an increasingly serious issue. Due to poor waste disposal, the use of fertilizers and pesticides, the quickly expanding farming and the metal sector, and other factors, Our ecosystem, soils, and rivers are being contaminated by these inorganic pollutants. This research shows the path that pollutants take once they reach the ecosystem and what happens to them thereafter. Certain metals affect biological processes and development, while others accumulate in one or more organs and cause a range of fatal illnesses, including cancer. The toxicological and pharmacokinetic properties of each metal in humans are explained. The review highlights the physiological and biochemical effects of each heavy metalââ¬â¢s bioaccumulation in humans, along with the conditionââ¬â¢s worrisome severity.
