California’s 1 million farmworkers are at increased risk for respiratory diseases and other health problems, according to a new report, in large part due to poor air quality where they are working.

Pesticides and other chemicals are part—but only part—of the air quality issues that affect farm workers, especially in California’s Central Valley. So even the most basic measures to shield workers from the worst of the dust and smog can make a significant contribution to protecting their respiratory health, says Marc Schenker (right),  Director of the Center for Agricultural Health and Safety at the University of California at Davis.

The study cited in this North Bay Report was published in the current issue of the quarterly journal, California Agriculture. You can access a summary or the full text of that article here.
