Overview
Product pages organize heavy-metal evidence around the item a reader starts from, rather than the metal or ingredient inside it. The catalogue spans 34 categories: the food supply (infant and child foods, grains and cereals, seafood, dairy, produce) alongside the non-food products regulated with it (personal care and cosmetics, household cleaning, pet foods and supplements, children’s toys). Each category page sorts its products into subcategories, and each product page summarizes the occurrence evidence for that item: typical and upper-percentile concentrations, how many sources support them and how strong those sources are, where the data are still thin, and the regulations that apply.
The catalogue reports what the peer-reviewed and regulatory literature supports. It does not rank brands and it does not publish certification limits. Begin here when a question starts with a product type; begin at Metals when it starts with a contaminant, or Ingredients when it starts with a raw material.
