Air quality regulators are investigating metal-processing facilities in the city of Paramount after detecting a potent cancer-causing metal at 350 times normal levels. “We’re really focused on finding the precise source of these high levels,” Fine said. AQMD officials emphasized that the high levels detected, though concerning, are not an immediate threat. Carlton Forge Works has said that once contacted by air quality officials a few years ago, it took immediate steps to reduce its nickel emissions. At least three sets of rules to cut pollution from operations that forge, grind, finish and treat metal are scheduled for consideration by the air quality board starting next year.
