(Portland, OR)  --  An air-pollution report by the Oregon Department of Environmental Quality is prompting a glass company in Southeast Portland to suspend its use of arsenic and cadmium.  DEQ reported earlier this week that high levels of the metals were detected in air-quality testing in Southeast Portland.  The tests were performed in the area of Southeast 22nd Avenue and Powell Boulevard, near Bullseye Glass Company.  KPTV reports the company is working with an environmental consulting firm to help evaluate the data and conduct more testing and monitoring.
