A study out of the University of Iowa finds high levels of the compounds D4 and D5 in Chicago’s air.

D4 and D5 are compounds found in many personal care products including deodorants, soaps, lotions, shampoos and conditioners.

The study found that concentrations of the compounds were 10 times higher in Chicago than West Branch, IA and four times higher than Cedar Rapids, Iowa.

There is no evidence that high concentrations of D5 pose health concerns to people. However, not much is currently understood about the compound.

D4 is toxic to wildlife, and caused tumors, reproductive problems and altered organ size in studies of lab animals.
