Heavy Metal Pollution In Environment And Their Toxicological Effect On Plants And Living Organisms

Abstract

Heavy metals normally occur in nature and are essential to life but can become toxic through accumulation in plants and living organisms. Arsenic, cadmium, chromium, copper, lead, nickel, and mercury are the most common heavy metals which can pollute the our environment. Most of the heavy metals causes environmental and atmospheric pollution, and may be lethal to plant. Heavy metal’s can become strongly toxic by mixing with different environmental elements, such as water, soil, and air plants and other living organisms can be uptake to them through the food chain.
