On August 21, 2014, US EPA released the Second
Integrated Urban Air Toxics Report to Congress. This is the final of two
reports required by the 1990 Clean Air Act (CAA) to inform Congress on
the process in reducing public health risks from urban air toxics.
A copy of the complete report is available here.
Dioxin
The urban air toxics program groups
dioxins, furans and dioxin-like PCBs in the dioxin category. There are a
total of 29 of these compounds. Seven dioxins, ten furans and 12
dioxin-like PCBs are included in the urban air toxics dioxin category.
Dioxin levels are down 95 percent from 1987 to 2000 (from 12.8 kg TEQs
to 0.07 kg TEQs). The US EPA has released strict dioxin standards for
municipal waste incinerators, medical waste incinerators and other
man-made dioxin sources.
A list of the 30 urban air toxics can be
found here.
