There is a growing concern over the
effects of air pollution and air toxins on human
health. While research continues to better understand
these links, there is already solid evidence of
health concerns with higher levels of ozone and
particulate matter.
Visitors to Sequoia and Kings Canyon National Parks
are made aware of daily quality by our air advisory
program. Predicted levels of ozone are translated
into an air quality index which alerts the public to
unhealthy air quality. This information is widely
distributed to employees and is posted at the three
largest visitor centers in the Parks.
