Three heavy metals Cadmium (Cd), Chromium (Cr) and Lead (Pb) were investigated in samples (almonds, teguments, fresh juice and fermented juices) of cocoa (cocoa mercedes). The Cocoa “Mercedes” is promoted in Côte d'Ivoire to substitute the old plants in order to increase the productivity. The cocoa samples were collected from two (2) experiment stations (Abengourou (East) and Divo (Southwest)) and two (2) extension stations (Adzope (Southeast) and Yamoussoukro (Central)) of Côte d' Ivoire. Each sample was mineralized by digestion (3:1 HF: HNO3) and purified. The purified liquid extract was analyzed by Atomic Absorption Spectrometry (AAS) with graphic furnace according to Quality Control /Quality Assurance QC / QA procedures. The results revealed the bioavailability of the tree heavy metals with variable concentration in different parts of the cocoa. The lowest concentrations were observed in Cr (mean: 4.50 - max: 8.90). The study brought up the concentrations (in µg / kg) higher for Pb (mean = 454.17 and max = 1690. 00) and Cd (mean = 126. 08 and max = 644.00)
