"Heavy metals toxicity and its effect on human health"

Abstract:

Heavy metal poisoning is the exposure of heavy metal toxins to human body in smaller scale which then accumulates and in the body being exposed increasing the concentration of these heavy metals leading to various health hazards. Some heavy metals are lead, mercury, arsenic, cadmium etc. these metals are abundantly and naturally present in the environment and almost a large population is exposed to these metals, but depending on the amount and type of heavy metal exposed humans are affected accordingly. In past years a lot of diseases have been reported caused due to heavy metal toxicity leading to a large number of lives being lost.  Heavy metals prevents the cells in the body affected by these metals to function properly binding them from doing their job, it can be life threatening and causes permanent damage to human health, there are many sources and many are man-made like industrial processes, mining etc. numerous health hazards occur in human body which stays with the patient for a very long time. The presence of these heavy metals in environment causes a lot of harm to the environment as well. In today’s generation, the concentration of these metals have increased constantly and leaves a huge impact to human population. Some toxins are arsenic, cadmium, lead, chromium and nickel, heavy metals are characterized by their high atomic mass and toxicity. Nanotechnology based experiments are being developed, as an emerging field, nanotechnology is making its advances in the analyses and removal of heavy metals from complicated matrices.
