Santa Clarita Valley residents live next to the nation’s dirtiest air polluter, according to the American Lung Association in its annual report on air quality.

The association handed down the nation’s report card on air quality Wednesday showing, once again, that Los Angeles remains the No. 1 most polluted city in America when it comes to the ozone layer.

The good news, according to the association’s county representative, is that Los Angeles is getting better despite being the most polluted city.

“We’re better off than we were years ago,” said Maria Bernabe, spokeswoman for the association in Los Angeles. “LA has always been No. 1. But if you look at the trend, we’re actually improving.”

The Los Angeles area examined by the association, found one of the 25 most ozone-polluted cities, includes most of Los Angeles County from Riverside to Long Beach, including Santa Clarita.

The ozone layer is a layer in Earth’s atmosphere, between about eight and 25 miles above the planet. Pollution that depletes the ozone layer can be harmful to humans, animals and plant life since the layer absorbs almost all of the sun’s harmful ultraviolet light.

Excessive exposure to harmful ultraviolet rays allowed through the layer because of pollution can, in some cases, lead to skin cancer.
