Status of Contamination in the Coastal United States as Revealed from NS&T Analyses of Surface Sediments
Sediment samples have been collected from more than 300 sites along the coasts of the U.S. since 1984 as part of NOAA's National Status and Trends (NS&T) Program. These samples...

Temporal Trends of Chemical Contamination at NS&T Sites
Recent temporal trends in concentrations of ten trace elements (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) and of five groups of organic compounds (butyltins, tDDT, tCdande, tPCB, and...

The NS&T Intensive Bioeffects Surveys: Design Strategies and Preliminary Results
Intensive bioeffects surveys are conducted in selected areas where chemical data from the National Status and Trends (NS&T) Program indicate greatest potential for contaminant-related...

Recovery of Shoreline Ecosystems Following the Exxon Valdez Oil Spill and Subsequent Treatment
High-pressure, hot-water washing was evaluated as one of several countermeasures for cleaning oiled shorelines. This was the primary treatment method for nearly all treated shorelines...

GIS and Laboratory Study Contaminants in Wetlands
Geographical Information Systems (GIS) provide excellent visualization and analyses of where pollution sources are located relative to existing wetland resources and areas of significant...

Evaluation of Dissolved Oxygen and Nutrient Trends in the Houston Ship Channel from Historical Statewide Monitoring Data
Dissolved oxygen and selected nutrient trends in the Houston Ship Channels (Texas Water Commission (TWC) segments 1007, 1006 and 1005) during the period of 1969 through 1990 were evaluated...

Effects of Estuarine Habitat Quality on Juvenile Salmon: I. Chemical Contaminant Exposure and II. Altered Growth and Immune Function
Some urban estuaries on the west coast of the US are important habitats for several species of juvenile salmon and receive multiple stresses from human activities. Because these estuaries...

Proposed Storm Water Management Programs: An Opportunity for Coastal Municipalities to Improve Water Quality
On November 16,1990, the Environmental Protection Agency (EPA) promulgated a final regulation establishing National Pollutant Discharge Elimination System (NPDES) permit application requirements...

Modern Air Pollution Reduction Technology on Platforms in the Pacific OCS
The Pacific Outer Continental Shelf (OCS) along the California coast line has the most sophisticated air pollution reduction technologies implemented in the world. This paper describes...

Sandy Beach Restoration in Heavily Populated Areas
Urban coastal areas are marked by several conflicts between its use and the conservation of its use and the conservation of its natural features. The Rio de Janeiro State University -...

The Source of Sediments in the Neuse River Estuary: Water Quality Management Implications
Pedological evidence in alluvial floodplains of the fluvial-estuarine transition zone of the Neuse River, North Carolina, shows that very little sediment from the Piedmont headwaters of...

Heavy Metals Contamination and its Implication in the Development of the Estuarine Zone of the Southern China
During the pat decade, the economic growth of the estuarine region of the Southern China has been astonishingly rapid. One of the major concerns has been the water pollution problem because...

Heavy Metal Accumulation in Subsurface, Estuarine Sediments and Inferences for Anthropogenic Enrichment: N.W. Florida Coast
In an attempt to quantify the degree of contamination and the thickness of the contaminated subsurface sedimentary wedge, approximately 100 samples were extracted from the cores and subjected...

Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...

HAZMAT?Protecting Coastal Resources from Pollution Emergencies
As we've seen over the years, pollution from accidental spills and hazardous waste sites can harm the coastal environment. What can be done? A critical step towards ameliorating the problem...

NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...

Methods to Assess Ecological Risk Used at Superfund Mega-Sites
This paper presents a variety of approaches that have been used (or are proposed) to address the potential ecological risks posed by contaminant releases from Superfund mega-sites. The...

Evaluating Remedial Alternatives for Coastal Wetlands in New Bedford Harbor
The Acushnet River estuary in upper New Bedford Harbor is highly contaminated with polychlorinated biphenyls (PCBs) and metals. Portions of the industrialized estuary are bordered by wetlands,...

Contaminant Trends in the Southern California Bight: The Coast is Cleaner
Data from local, regional and federal coastal monitoring programs were used to assess long-term trends and spatial extent of chemical contamination in sediments, shellfish, and fish of...

NOAA's Damage Assessment Program: Past, Present, and Future
This paper reviews trustee authorities established under the Super fund Act of 1980 and the Oil Pollution Act of 1990 to provide an introductory framework for more detailed presentations...
