Several heavy metals are found naturally in the earth crust and are exploited for various industrial and economic purposes. Among these heavy metals a few have direct or indirect impact on human health, Plants and Soil. These are all naturally occurring substances which are often present in the environment at low levels. In larger amounts, they can be dangerous. Some common heavy metals are arsenic, barium, cadmium, chromium, lead, mercury, selenium, Copper, Cobalt, Iron and Nickel. Heavy metals exhibit toxic effects towards soil biota by affecting key microbial processes and decrease the number and activity of soil microorganisms. Even low concentration of heavy metals may inhibit the physiological metabolism of plant. These metals are released into the environment by both natural and anthropogenic means, especially mining and industrial activities. They leach into the underground waters, moving along water pathways and eventually depositing in the aquifer, or are washed away by run-off into surface waters thereby resulting in water and subsequently soil pollution. Heavy metals are also impact on human health. Generally, humans are exposed to these metals by drinking or respiration. Working in or living near an industrial site which utilizes these metals and their compounds increases ones risk of exposure, as does living near a site where these metals have been improperly disposed. Therefore this paper reviews certain heavy metals and their virulent effect on Plants, Soil and Human Health.
