There is a growing awareness regarding the levels of arsenic in many types of food and beverages. However, the relative toxicity of the arsenic depends largely upon the species of arsenic that is present. Regulators and manufacturers are increasingly interested in distinguishing between the various species of arsenic found in food and beverages, and not just the total arsenic concentrations, when addressing human health concerns. The analytical techniques for determining the specific arsenic species in food and beverages can vary considerably from laboratory to laboratory. On behalf of the AOAC Contaminant Community, Brooks Rand Labs is conducting an arsenic speciation interlaboratory comparison study.
