Analysis of Heavy Metal Content in Canabis Leaf and Seed Cultivated in Southern Part of Nigeria

Abstract

The distribution of heavy metals content in cannabis leaf and seed were assayed / carried, using an atomic absorption spectrometers model Perkin Elmer 3110. The heavy metals determined in both samples mean arsenic, cadmium, chromium, iron, nickel, lead mercury and manganese. The results obtained revealed that metal levels in cannabis leaf exceeded those of cannabis seed except in manganese, which had the highest metal content among all the metals determined. The results furthers showed that As, Cd., Cr, Fe, Ni, Ph and Hg levels in cannabis leaf exceeded those of the cannabis seed. Therefore cannabis leave seems to be more dangerous to health than the seeds.
