What’s the most harmful kind of air pollution? It’s soot generated by diesel engines found in trucks, buses and ships. Diesel engines are the durable workhorses of transportation, but as they get older, they spew unhealthy soot. They are now challenging community activists and government officials to find creative solutions for at-risk areas like West Oakland, California.

Producer’s Notes — Perilous Diesel 14 March,2016Gabriela Quirós


Gabriela Quirós

Gabriela Quirós is a video producer for KQED Science and the coordinating producer for Deep Look. She started her journalism career 25 years ago as a newspaper reporter in Costa Rica, where she grew up. She won two national reporting awards there for series on C-sections and organic agriculture, and developed a life-long interest in health reporting. She moved to the Bay Area in 1996 to study documentary filmmaking at the University of California-Berkeley, where she received master’s degrees in journalism and Latin American studies. She joined KQED as a TV producer when its science series QUEST started in 2006 and has covered everything from Alzheimer’s to bee die-offs to dark energy. She has won five regional Emmys and has shared awards from the Jackson Hole Wildlife Film Festival, the Society of Professional Journalists and the Society of Environmental Journalists. Independent from her work in KQED's science unit, she produced and directed the hour-long documentary Beautiful Sin, about the surprising story of how Costa Rica became the only country in the world to outlaw in vitro fertilization. The film aired nationally on public television stations in 2015.
