Air quality throughout the Bay Area took a big hit over the past week, mainly due to the plumes of smoke coming from the Oak Fire near Yosemite. That smoke has led the Bay Area Air Quality Management District to extend its smoke advisory several times. The air advisory is set to expire today.

For more on this, KCBS Radio news anchors Melissa Culross and Eric Thomas spoke with Joel Burley, professor in the Chemistry Department in the School of Science at Saint Mary's and an expert on air pollution.
