Sites along the Elizabeth River are contaminated with polycyclic aromatic hydrocarbons (PAHs) from historical creosote production and other industrial processes. Previous studies have demonstrated that Atlantic killifish collected from sites througho

The increasing occurrence of tetrabromobisphenol A (TBBPA) in the environment is raising questions about its potential environmental health impacts as it has been shown to cause various deleterious effects in humans. The fact that the highest concent

article i nfo We analyzed eight sediment cores from wetland and subtidal locations around San Francisco (SF) Bay, terrace sediment from the Yuba River, CA and precipitation from the SF Bay region. We defined the Hg isotopic com- position of uncontami

Mercury (Hg) concentrations and isotopic compositions were examined in shallow-water surface sediment (0–2 cm) from San Francisco (SF) Bay to determine the extent to which historic Hg mining contributes to current Hg contamination in SF Bay, and to

The concentrations of mercury (Hg) and other trace metals (Ni, Cu, Zn, Mo, Ba, Re, U) and the Hg isotopic composition were examined across a dramatic redox and productivity transition in a mid-Pleistocene Mediterranean Sea sapropel sequence. Characte

Identification of sources of biologically accessible Hg is necessary to fully evaluate Hg exposure in aquatic ecosystems. This study assesses the relationship between Hg in forage fish and Hg in surface sediments throughout San Francisco Bay (SF Bay)
