Supervisors will hear health study about ozone

In 1992, the California Air Resources Board began studying the health effects that chronic exposure to ozone had on children.

Researchers discovered that children living in communities with high ozone – a component of smog – were more likely to develop asthma and had significantly higher school absences due to respiratory illness.

You can learn more about that Tuesday, when Barbara Weller, an official from the state air board, will speak about the study to the Nevada County Board of Supervisors.

Supervisor Bruce Conklin would like a similar study done here. In a memorandum to fellow supervisors, he wrote that Grass Valley has some of the highest ozone levels in the state and “most of it originates in the tailpipes of the Bay Area and Sacramento Valley.”

That’s one reason county supervisors supported a bill seeking tougher smog tests in the Bay Area, a bill that’s currently in the State Assembly, Conklin wrote.

Also speaking at Tuesday’s hearing will be Charles Johnson, Nevada County health officer; and Gretchen Bennitt, the air pollution control officer for the Northern Sierra Air Quality Management District, which includes Nevada County.
