Abstract
Heavy metals are defined as metals with a density higher than 5 g cm−3. Of about 90 naturally occurring elements, 53 are considered as heavy metals. A total of 18 elements are considered essential for plant nutrition. A few of the elements are considered beneficial. They are not essential for plant nutrition but provide indirect benefit to the plants and animals who consume the plants.
