Heavy Metal Exposure in Common Childhood Food Staples - The Peanut Butter and Jelly Studies

In this study, dried fruit samples (organic and regular raisins, sultanas and currants) and bread spreads (from different nuts and seeds; i.e. peanuts, almonds, sunflower etc.) were purchased from stores in the US, UK and Germany. Samples were digested using microwave digestion and tested by ICP-MS to determine heavy metal contamination and potential exposure.
