Dioxins Releases by Industry in the 2015 TRI National Analysis
See All Graphics in this Section
The following two pie charts show: 1) the industry sectors that reported the greatest releases of dioxin and dioxin-like compounds in grams, compared to 2) the industry sectors that reported the greatest releases of grams in toxicity equivalents (grams-TEQ).
- Various industry sectors may dispose of or otherwise release very different mixes of dioxin congeners.
- In 2015, four industry sectors accounted for most of the grams and grams-TEQ of dioxins released.
- The chemical manufacturing industry accounted for 46% and the primary metals sector for 49% of total grams of dioxins released.
- However, when TEFs are applied, the primary metals sector accounted for 84% and the chemical manufacturing sector for just 12% of the total grams-TEQ released.
