Research Program Area: Health & Exposure
A network of air monitoring sites have been operating as part of the Southern California Children's Health Study since 1994. Concentrations of fine particle mass and ions, as well as gas-phase acids, have been measured continuously since 1994. This report presents the particulate organic carbon (OC) and elemental carbon (EC) concentrations measured during the first five years of this monitoring program. The OC / EC data show seasonal and annual trends as well as spatial trends in carbon particle concentrations across the southern half of California. These data will assist the Children's Health Study investigations in the interpretation of their health effects data.
