A new test for arsenic around Uroboros Glass in North Portland showed levels several times higher than the state guideline.
But David Farrer with the Oregon Health Authority said people needn’t be concerned.
“When there’s an exceedance of a screening level found, that does not automatically mean that there’s a public health risk,” Farrer said. “But it does mean that we need to do additional analysis, and found that the risk was low.”
Concerns about toxic air started last month after high levels of heavy metals were found around glass manufacturers in the city.
Since then, Uroboros has signed an agreement not to use the heavy metals without a filter. Bullseye Glass remains in negotiations.
