What Portion of the Hazardous Waste Trade
is in Toxic Material?

What percent of materials are toxic?

The data for this map comes from EPA's Chemical Hazard Information Profiles (CHIP). A material is considered cancer-causing, environmentally degrading, or a workplace hazard if it has been listed on the Toxic Releases Inventory list as such. For carcinogens, we also consider placement on the National Toxicology Program list as a known or "reasonably anticipated" carcinogen. Percentages are calculated as proportion of import shipments that contained a toxic. Waste mercury accounts for some of these shipments.
