Air regulators say they're expanding their efforts to monitor pollutants in the Bay Area, following last month's Chevron refinery fire. In a Board hearing for the Air Quality Management District, executive director Jack Broadbent said his agency's efforts "clearly fell short," and the community deserves real-time information about air pollutants.
 
"They don't want to just necessarily be told to shelter in place." Broadbent said. "They also want to be told: what am I breathing. I think that's very reasonable, I think that makes a lot of sense. The technology today doesn't allow us to tell the community that well."

Broadbent says his agency currently cannot, but should be able to, analyze the air pollutants of greatest concern right now: soot and particulate matter.
