DEQ releases preliminary map of heavy metal emissions

Posted: Updated:

The Oregon Department of Environmental Quality released a map Friday outlining the preliminary areas where concentration of heavy metals including cadmium are “potentially at levels of concern.”

This map comes after an earlier announcement this week of high levels of cadmium and arsenic being found in the air near the Bullseye Glass Company in southeast Portland.

On their website Friday, the DEQ noted the map was created with limited data, focusing on correlating cadmium concentrations in the air with that in moss, a method the department describes as "still in development and prone to refinement."

The DEQ also stressed that the map was not meant to be seen as exact in terms of hard boundaries or concentration levels, but instead to be a piece of “initial information about potentially affected areas.”

The Oregon Health Authority reports that health effects from exposure to arsenic and cadmium depend on how much a person is exposed and for how long.

Thursday Bullseye Glass announced the company was suspending the use of arsenic and cadmium, and was working with outside firms to conduct further environmental testing and monitoring.
