In response to mercury contamination of the Bay-Delta and potential risks to humans, health advisories have been posted in the estuary, recommending no consumption of large striped bass and limited consumption of other sport fish. The major objective of the CALFED Bay-Delta Mercury Project “Assessment of Ecological and Human Health Impacts of Mercury in the Bay-Delta Watershed” is to reduce mercury levels in fish tissue to levels that do not pose a health threat to humans or wildlife. This report summarizes the accomplishments of the Moss Landing Marine Laboratories (MLML) and California Department of Fish and Game (CDF&G) at Moss Landing as participants in the CALFED Bay-Delta Mercury Project. Specific objectives of MLML and CDF&G include: 1.

The Bay Plan was prepared by the Commission over a three-year period pursuant to the McAteer-Petris Act of 1965 which established the Commission as a temporary agency to prepare an enforceable plan to guide the future protection and use of San Francisco Bay and its shoreline. In 1969, the Legislature acted upon the Commission’s recommendations in the Bay Plan and revised the McAteer-Petris Act by designating the Commission as the agency responsible for maintaining and carrying out the provisions of the Act and the Bay Plan for the protection of the Bay and its great natural resources and the development of the Bay and shore- line to their highest potential with a minimum of Bay fill.

Beginning around Vallejo and running roughly six miles to Suisun Bay, Grizzly Bay, and the Sacramento possesses a T River Delta, the Strait has, in the daily life of California, reduced down to the Carquinez and Benicia-Martinez bridges. Motorists are as likely to be searching for grim grandeur. their toll as looking at the land and water below. Few will exit the interstates. Why stop at Martinez, Benicia, Vallejo, Crockett, or Port Costa? They are going west to Napa or San Francisco or east to Sacramento. Like travelers’ destinations, California’s future also appears to lie elsewhere. Once, much of what moved out of Northern California came through these communities, but now the Strait seems left with only the detritus of California’s past. The detritus still possesses a grim grandeur. To the east, the Mothball Fleet— originally composed of transports and battleships that helped win World War II— cluster tightly together, toxic and rusting, in Suisun Bay. Just west of the bridges, Mare Island (really a peninsula with a slough running through it) sits across the mouth of the Napa River. The United States established a naval base and shipyard there in 1854, and the island remained central to US military efforts from the Civil Boom: A Journal of California, Vol. 2, Number 2, pps 55–69.

  • Health Impact Analysis of Fine Particulate Matter in the San Francisco Bay Area
    Health Impact Analysis of Fine Particulate Matter In the San Francisco Bay Area 1. Introduction 1.1 Background Fine particulate matter (PM2.5) is a complex mixture of suspended particles and liquid droplets in the atmosphere having aerodynamic diameters of 2.5 µm or less. An individual particle typically begins as a core or nucleus of carbonaceous material, often containing trace metals. These primary (directly emitted) particles usually originate from incomplete combustion of fossil fuels or biomass. Layers of organic and inorganic compounds are then deposited onto particles while they coalesce, causing the particles to grow in size. The deposited layers include secondary material that is not emitted directly. Secondary components instead form through chemical reactions of precursor gases released from combustion, agriculture, household activities, industry, vegetation, and other sources. As particles grow larger, gravity eventually causes them to settle onto surfaces. Most naturally emitted dust particles have diameters too large to be classified as PM2.5. Numerous studies have demonstrated PM2.5 to be deleterious to human health. Major human health outcomes resulting from PM2.5 exposure include aggravation of asthma, bronchitis, and other respiratory problems, leading to increased hospital admissions; cardiovascular symptoms, including chronic hardening of the arteries and acute triggering of heart attacks; and decreased life expectancy, potentially on the order of years. Smaller particles have increasingly more severe impacts on human health than larger particles. This occurs in part because smaller particles are able to penetrate more deeply into the human body. The United States Environmental Protection Agency (US EPA) has developed a computer program, named the Environmental Benefits Mapping and Analysis Program (BenMAP), to estimate health impacts associated with changes in ambient levels of pollutants.

  • PAH) Contamination in San Francisco Bay: a 10-Year Retrospective of Monitoring in an Urbanized Estuary

Orosa, John R.M. Rossa,Ã, Robert B. Spiesb, Thomas Mumleyc aSan Francisco Estuary Institute, 7770 Pardee Lane, 2nd Floor, Oakland, CA 94621, USA bApplied Marine Sciences, 4749 Bennett Drive, Suite L, Livermore, CA 94550, USA cCalifornia Regional Water Quality Control Board, San Francisco Bay Region, 1515 Clay Street, Suite 1400, Oakland, CA 94612, USA Received 21 July 2006; received in revised form 21 September 2006; accepted 20 October 2006 Available online 14 December 2006 Abstract Polycyclic aromatic hydrocarbons (PAH) are widespread contaminants in the San Francisco Bay. Several exceedances of water quality criteria raise the possibility that PAH may be impacting aquatic biota. The Regional Monitoring Program for Water Quality in the San Francisco Estuary (RMP) has collected annual monitoring data on PAH in the Bay since 1993. Analysis of Bay water, sediment, and mussel SPAH concentration data showed that there were very few significant (Po0.05) increasing or decreasing temporal trends in SPAH concentrations in the Bay during the period of 1993–2001. Wet and dry season input of PAH did not show any major influence on water SPAH concentrations over the same period. Based on their relative contribution to the estimated total maximum PAH loading (10,700 kg/yr) into the Bay, the PAH loading pathways are ranked as storm water runoff (51%)4tributary inflow (28%)4waste- water treatment plant effluent (10%)4atmospheric deposition (8%)4dredged material disposal (2%).
