Releases of Dioxin and Dioxin-like Compounds by Sector

This figure shows the releases of dioxins in grams and grams-TEQ. Various industry sectors may dispose of or otherwise release very different mixes of dioxin congeners. Four industry sectors accounted for most of the grams and grams-TEQ of dioxins released in 2013; however, their ranking in terms of percentage of total grams and grams-TEQ is quite different.

In 2013, the chemical manufacturing industry accounted for 67% of the total grams of dioxins released, while the primary metals sector accounted for only 26% of the total grams. However, when TEFs are applied, the primary metals sector accounted for 70% of the total grams-TEQ, and the chemical manufacturing industry accounted for just 10%.
