Two major rivers in California influenced by a Mediterranean climate are the Sacramento River and the San Joaquin River. The Sacramento River drains 72,132 km with a relief of 4,317 m. Mean discharge is 650 m /s with peak flows in the winter and early spring and with minimum flows in the late summer and early fall. The San Joaquin River drains 83,409 km with a relief of 4,418 m. Mean discharge is 130 m /s with peak flows in spring and low flows in late summer and fall. Population density is 24 people/km in the Sacramento River basin and 29 people/km in the San Joaquin basin. Agriculture in the Central Valley of California that encompasses parts of both basins is the primary user of water in both basins [1]. 

Fig. 1 Map of the Delta in central California, USA with the California state map inset to show location within the state. The Delta is formed at the confluence of the Sacramento River and the San Joaquin River. Export of water from the Delta occurs mainly from the State Water Project pumping plant and the Central Valley Project pumping plant in the south Delta...

Ambient diazinon concentrations were measured under foggy atmospheric conditions in and around the Central Valley of California (Parlier, California), which is a prime agricultural area dominated by fruit, nut, and citrus orchards (Glotfelty et al. 1990a Seiber et al. 1993 Zabik and Seiber 1993). In fog, diazinon concentration was 1.6 ng/m3 and diazoxon (the oxon transformation product) concentration was...
