Metal Concentrations of Sediment from 1993-2017 in San Francisco Bay-Delta Estuary (San Pablo Bay and Suisun Bay), CA Surface sediment samples from the North San Francisco Bay-Delta Estuary were collected monthly at five stations located west of Rio Vista and east of Point Pinole. Sediment was collected near Montezuma Slough, Chips Island, the Concord Naval Weapons Station, Carquinez Strait near Martinez, and San Pablo Bay at water depths ranging from 6.5 to 14.3 meters. Samples were collected coincident with water-quality measurements (Cloern and Schraga, 2016) and metal concentrations in filter-feeding bivalves (Brown and Luoma, 1995; Stewart et al., 2013). Depending on the station, the period of record ranges from 13 to 24 years, from December 1993 to September 2017. Samples were sieved to <64 µm to eliminate grain-size bias...

Andrews, Longitudinal dispersion of metals in the Clark Fork River, Montana, Lewis Publishers, 1987). Tailings deposited along the floodplain, streambanks and river channel continue to contribute metal contaminated material into the river in the form of metal-enriched particulate matter or seston, comprising a mixture of organic and inorganic materials (J.N. Moore and S.N. Luoma, Hazardous wastes from large-scale metal extraction: A case study. Environmental Science and Technology, v.24:1278-1285, 1990). Metal enriched seston poses a dietary exposure risk to filter-feeding...
