(Salem, OR)  --  Governor Kate Brown says she's taking "immediate steps" to address the elevated amounts of toxic metals in the air in north and southeast Portland neighborhoods.  The Oregon Department of Environmental Quality says tests have revealed levels of cadmium, arsenic, and chromium in areas of the city.  At the request of DEQ, two Southeast Portland glass companies voluntarily refrained from using arsenic and cadmium in their manufacturing.  Brown says the Oregon Health Authority will work with DEQ and Multnomah County to address other potential routes of exposure to people in the affected neighborhoods.
