Sample Preparation and ICP-MS Analysis of Trace Metals in Foods


Introduction

High level exposure to certain heavy metals can cause adverse effects on human health including impaired brain and cognitive development in children, cardiovascular disease, diabetes, and cancer, to name a few. Toxic heavy metals such as As, Cd, Pb, and Hg are present in our air, soil, and water and are persistent once released into the environment. These elements can accumulate in plants, and animals that eat these plants, and make their way into our food supply. Because of the adverse health effects of these metals, the FDA imposes strict limits on the amounts that may be present in the foods we eat.
