I find it a little ironic that Harold Burge of the Division of Air Quality (in Clipper July 17, 2013 “DAQ downplays Stericycle Danger”) claims residents should be more concerned with nitrogen oxides (NOX) than about dioxins/furans.
The difference between NOX and dioxins/furans is concentrations in parts per million versus parts per trillion, or a million times larger, due to differences in toxicity.
According to Mr. Burge, Stericycle only failed a dioxin test once, that being stack test. What Mr. Burge is not saying is how much dioxin/furan is coming out of the Stericycle non-pollution controlled bypass stack, but we need to remember that the danger level of dioxins/furans is “complicated” according to Mr. Burge.
