  Background: Calabash chalk geophagia commonly consumed in Sub-Saharan countries such as Cameroon may be a source of potential harmful elements such as lead and mercury. We sought to determine its geochemical composition on representative sample collected in the central market of Douala and evaluate their acute toxicity profile using rat. Methods: The geochemical analysis of three prototypes of Calabash chalk samples collected in the Douala central market, their main place of supply in the town, has been performed using the X-ray Fluorescence (XRF) and the inductively Coupled Plasma-Mass Spectrometry (ICPMS) for major and trace elements respectively. Acute toxicity was assessed according to Organisation for Economic Cooperation and Development (OECD) guidelines test No 423. Results: The geochemistry displays th.. Read More»
