(Portland, OR)  --  A class-action lawsuit is being filed by a group of seven Southeast Portland residents against Bullseye Glass Company, which has been linked to toxic levels of arsenic and cadmium found in air-quality tests.  The lawsuit claims the company has been polluting the area with a wide variety of chemicals used in the manufacture of glass since it opened in 1974.  Dan Schworer [[ SHWORE-er ]], president of Bullseye, says his company has always operated within federal and state guidelines regarding metal emissions.  The plaintiffs want Bullseye to pay for urine tests for those who live within a mile-and-a-half of the factory, and seek compensation for attorneys' fees.
