Medline and Sterigenics haven’t reported cancer-causing ethylene oxide emissions to the EPA’s pollution inventory for years

The Medline Industries facilities can be seen May 12, 2021, in Waukegan. People living near Medline Industries in north suburban Waukegan had higher levels of the cancer-causing chemical ethylene oxide in their bloodstream than others who live farther away, according to test results from a federally funded study in 2019.
