Los Angeles is located in an area known as the South Coast Air Basin (see map). Below are a few links that show both current air and water quality information for the regions between Irvine, Los Angeles, Santa Monica, San Fernando Valley, and up to Santa Barbara. Some reports show an AQI measurement. This is the Air Quality Index, and is a standardized measurement of several pollutants of which the one with the highest concentration is reported.
