Abstract
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers. A density of more than 5 g/cm3 is sometimes quoted as a commonly used criterion and is used in the body of this article. Heavy metals affects morpho- physiological and biochemical processes in the plants. Chromium, arsenic, cadmium, mercury, and lead have the greatest potential to cause harm on account of their extensive use, the toxicity of some of their combined or elemental forms, and their widespread distribution in the environment. Application of agro-based chemical fertilizers and pesticides with high heavy metals content should be avoided to keep high quality soils for sustainable use in the reservoir watershed and to prevent human and livestock health hazards and induce agricultural plant productivity.
