Download or read book Near Field Receiving Water Monitoring of Trace Metals and a Benthic Community Near the Palo Alto Regional Water Quality Control Plant in South San Francisco Bay California 2004 written by and published by . This book was released on 2005 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace elements in sediments and clams, clam reproductive activity and benthic community structure are reported for a mudflat one kilometer south of the discharge of the Palo Alto Regional Water Quality Control Plant in South San Francisco Bay. This report serves as a continuation of the Near-Field Receiving Water Monitoring Study, which began in 1974. Prior to this report, trace metal and reproductive activity/community structure data were reported separately. The data for 2004, herein, are interpreted within that context and are consistent with those previously reported. Metal concentrations in both sediments and clam tissue samples are within the range of values previously observed due to seasonal variability. Copper and zinc concentrations in sediment and bivalve tissue display continued decreases over the last decade. In 2004, copper in sediment was observed to drop below the ERL (Effects Range-Low) concentration for the fourth consecutive year. The concentration of zinc in sediment never exceeded the ERL. Yearly average concentrations of copper, zinc and silver for 2004 are some of the lowest recorded since monitoring for metals began in 1975. The concentrations of mercury and selenium, during April and January 2004, respectively, were the highest values observed for these elements during this study. However, the concentrations of these elements in sediments and clams at Palo Alto were similar to concentrations observed elsewhere in the San Francisco Bay.

Download or read book Trace Element and Nutrient Cycling in San Francisco Bay written by and published by . This book was released on 1998 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long term goal of this research is to examine the processes that control trace metal concentrations in near-shore waters. Within this context, we examine the role of chemical exchange across the sediment-water interface and the examine how changes in harbor processes will affect water column trace metal burdens. This research represents the collaboration between scientists with expertise on biogenic matter degradation (W.B., USC) and trace metal analyses (K. Coale and K. Johnson, Moss Landing Marine Labs) with the long-term goal to develop and integrated understanding of trace metal behavior in near-shore sediments.

Book excerpt: Indexes material from conference proceedings and hard-to-find documents, in addition to journal articles. Over 1,000 journals are indexed and literature published from 1981 to the present is covered. Topics in pollution and its management are extensively covered from the standpoints of atmosphere, emissions, mathematical models, effects on people and animals, and environmental action. Major areas of coverage include: air pollution, marine pollution, freshwater pollution, sewage and wastewater treatment, waste management, land pollution, toxicology and health, noise, and radiation.

Download or read book Trace Metal and Nutrient Cycling in San Francisco Bay written by and published by . This book was released on 1998 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long term goals of this project are to examine the influence of metal flux (primarily Cu, Cd, As, Co, Mn and Fe) from sediments on the concentration of dissolved metals in the coastal zone and embayments. The processes that control trace metal exchange across the sediment-water interface within coastal environments regulate the concentration of dissolved, bioactive metals in the water column. These processes include variations in the relative influence of transport mechanisms (diffusion versus bio-irrigation), microbial activity (anaerobic versus aerobic respiration), as well as geochemical reactions (redox reactions, precipitation, complexation and adsorption) that regulate the behavior of dissolved metals in pore waters. All of these processes are controlled by the activity and composition of the sediment community. The role of organic carbon remineralization on trace metal mobility at a biologically active interface is, therefore, the focus of this study.

This book was released on 1993 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentrations of trace metals in San Diego Bay are similar to concentrations in lower South San Francisco Bay, but San Diego Bay has not received any sewage discharges since 1964. Data evaluation reaches preliminary conclusion that levels of copper and other metals are largely determined by concentrations of those metals in sediments, which can remain relatively highly concentrated in pollutants decades after discharges cease.

Download or read book Managing Wastewater in Coastal Urban Areas written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close to one-half of all Americans live in coastal counties. The resulting flood of wastewater, stormwater, and pollutants discharged into coastal waters is a major concern. This book offers a well-delineated approach to integrated coastal management beginning with wastewater and stormwater control. The committee presents an overview of current management practices and problems. The core of the volume is a detailed model for integrated coastal management, offering basic principles and methods, a direction for moving from general concerns to day-to-day activities, specific steps from goal setting through monitoring performance, and a base of scientific and technical information. Success stories from the Chesapeake and Santa Monica bays are included. The volume discusses potential barriers to integrated coastal management and how they may be overcome and suggests steps for introducing this concept into current programs and legislation. This practical volume will be important to anyone concerned about management of coastal waters: policymakers, resource and municipal managers, environmental professionals, concerned community groups, and researchers, as well as faculty and students in environmental studies.
