It's the longest period of air pollution in a dozen years for the San Joaquin Valley. The situation is so bad that officials are warning the public to limit outdoor activities.

Officials said dirty air in the state's Central Valley has exceeded federal health standards nearly every day since the beginning of December.

The pollution is the unhealthiest kind, since it can get into lungs and absorbed into the blood stream, creating health risks for everyone.
