Dioxins Releases by Industry
The following two pie charts compare the TRI-covered industry sectors that reported the greatest releases of dioxins in grams to those that reported the greatest releases of grams in toxicity equivalents (grams-TEQ). Note that only data from those reporting forms that provided the congener detail for calculating grams-TEQ are included in these charts.
- Various industry sectors may dispose of or otherwise release very different mixes of dioxin congeners.
- The chemical manufacturing industry accounted for 60% and the primary metals sector for 13% of total grams of dioxins released.
- In terms of toxicity equivalents, however, the primary metals sector accounted for 46% and the chemical manufacturing sector for 20% of the total grams-TEQ.
