Heavy metals, also known as trace metalss are naturally occurring elements which are required in trace concentrations for the development and life processes of an organism. The various applications of heavy metals in industrial, agricultural, domestic, medical and technological applications have led to their wide distribution in the environment. This has raised concerns over their potential effects on human health and environment. The toxicity of the heavy metals depends on the concentration, route of exposure, duration of exposure as well as the age, gender and genetic makeup of the individual who is getting exposed. Azima tetracantha Lam. is a medicinal plant commonly found in India which has many medicinal and therapeutic values. The various parts of the plant have been administered to treating pyrexia, dropsy, dyspepsia, chronic diarrhea, diabetes and arthritis. As the plant is meant for consumption, it is needed to assess the concentration of trace metals present or accumulated in the plant before exploiting the medicinal values of the plant and its parts. This article aims for the same and reveals the concentration of trace elements Iron, Copper, Nickel, Cadmium, Chromium, Lead and Zinc which are found to be the predominantly occurring heavy metals in the polluted environment.
