Our air clean-up efforts have paid off a little. The risk of developing cancer from air pollution here has dropped 15 percent since 1998.
"The net result of the study is that while we have seen some improvements, the net risk level remains way too high in terms of public health threat," said AQMD executive officer Dr. Barry Wallerstein.
Residents of downtown L.A., Burbank, Fontana, Huntington Park and Wilmington were found to have the highest risk of cancer linked to air pollution.
