(RMP or Program) evaluates the concentration of pollutants in a wide range of matrices. Trace metals and organic compounds are monitored in water, sediments, bivalves, and sport fish as part of the Status and Trends element of the RMP (SFEI 2005, 2006b). Periodically, the cost-effectiveness and statistical power of the major elements of the RMP are(More)
Many microarray and suppression subtractive hybridization (SSH) studies have analyzed the effects of environmental stress on gene transcription in marine species. However, there have been no unifying analyses of these data to identify common stress response pathways. To address this shortfall, we conducted a meta-analysis of 14 studies that investigated the(More)
Bioaccumulation factors (BAFs) and biota-sediment accumulation factors (BSAFs) are frequently used to predict contaminant bioaccumulation in risk assessments. Development of these parameters is often hindered by uncertainty regarding the spatial scale of contaminant transfer from sediments to biota. We present a simple statistical method for optimizing(More)
The spatial and temporal distribution of macrobenthic assemblages in the San Francisco Estuary and Sacramento-San Joaquin River Delta were identified using hierarchical cluster analysis of 501 samples collected between 1994 and 2008. Five benthic assemblages were identified that were distributed primarily along the salinity gradient: (1) a polyhaline(More)
Bivalve molluscs are excellent water quality biosentinels. Long-term monitoring of contaminants in bivalves at coastal California locations has yielded excellent documentation of the significant declines in concentrations of some contaminants that have occurred, and has identified some areas where recovery is progressing more slowly. This report presents(More)
This study integrated monitoring data collected by the Regional Monitoring Program for Water Quality in the San Francisco Estuary (RMP), the Coastal Fish Contamination Program, and City and County of San Francisco (CCSF). The objective of the study was to investigate patterns in contamination in the Bay and on the adjacent coast, with respect to human(More)
Executive Summary The objective of this study was to test a method for benthic stressor identification in the San Francisco Estuary. Benthic assessments often identify samples that are impacted for various reasons (e.g., organic enrichment, disturbance, or contamination), but few studies have statistically associated specific contaminants or mixtures, with(More)
Executive Summary This report presents a concept and demonstration for a Water Contamination Index (WCI) for San Francisco Estuary. The purpose of this index is to assess impacts of exposure to water contamination on aquatic life in San Francisco Estuary. It is intended that the WCI will be one component in a broader Estuary Contaminant Index that includes(More)
