Abstract:
Mussel Watch represents the longest running continuous contaminant monitoring program in U.S. coastal and Great Lakes waters and was created in response to concerns over environmental quality of the Nation's coastal and estuarine ecosystems. This project analyzes chemical and biological contaminant trends in sediment and bivalve tissue collected at over 280 coastal sites from 1986 to present. Parameters monitored include sediment and bivalve tissue chemistry for over 100 organic and inorganic contaminants; bivalve histology; and Clostridium perfringens (pathogen) concentrations. This project regularly quantifies PAHs, PCBs, chlorinated pesticides including DDT and its metabolites, TBT and its metabolites, and trace elements.
Purpose:
The main objectives of the Mussel Watch Project are to evaluate the ecological status of the estuaries and coasts of the US, determine change in environmental quality through time (trends), and support NOAA ecosystem-based management. This work is performed along the conterminous coasts of the U.S. and the shores of the Great Lakes, Hawaii and Alaska. Samples are also regularly collected in Puerto Rico. Mussels and oysters are the sentinel species of the Project and sites are collected and analyzed biennially with contaminants characterized in sediment approximately once every ten years. Mussels are collected from sites historically collected by state monitoring programs and other forerunners of the current Project. The Project's data are available back to 1986 but certain parameters can be compared to earlier monitoring of the 1960s and 1970s.These interrelated activities are designed to provide coastal managers with national context to measures of local and regional environmental condition. Outcomes include a status of contaminant concentrations around the U.S. including Alaska, Hawaii, Puerto Rico and the Great Lakes. Monitoring activities are designed to quantify and assess spatial and temporal trends in coastal contamination, and to provide a baseline to assess impacts of anthropogenic and natural events, including chemical spills, tropical storms, and hurricanes.The NS&T Mussel Watch Project is not intended to quantify contaminants in "hot spots;" rather, mollusk collection sites were selected to be representative of their surroundings. Therefore, Mussel Watch sites were not located in areas such as New Bedford Harbor, where PCB concentrations are known to be uniquely high, or near waste discharge points or poorly flushed industrialized waterways.
Supplemental_Information:
All Mussel Watch data is entered into at least one of the following seven files: Analyte, Site, Station, QA/QC, Field, Lab and Histopathology. There are also about twenty supplementary look-up tables that give the users information about data used in this dataset. The Analyte File consists of the chemistry sample data. It has all analyte, method detection limit, units and method data. The units that these parameters are stored in is: percentage for grain size data, in ug/dry g for trace metals, in ng Sn/dry g for butil tyn data and in ng/dry g for everything else. The Site File is where the nominal site data is stored. This stores the latitude and longitude of a site as well as the sequence number, region and watershed data. The latitude and longitude is measured using datum NAD83. The Station File stores the data of where a site was sampled each year it was collected or where multiple stations were collected within a site area. The Field File is where data about Field conditions is stored e.g. temperature and salinity. The QA/QC File is where all of the QA data are stored. This consists of Procedural Blanks, Duplicates, Matrix Spikes, Matrix Spike Duplicates and Standard Reference Materials (SRMs) for each batch from 1990 to the present. The Histopath File is where all histopathology and gonadal index data are stored.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The measurement quality objectives of Mussel Watch specify accuracy and precision requirements of 30% for organic analytes and 15% for inorganic analytes in sediment and tissue samples. QA procedures include running blanks, spiked samples, and standard reference materials with each batch of samples. Any batch failing to meet the specifications is reanalyzed or rejected. The QA Criteria may be found in NOAAs Tech Memo 71, and Tech Memo 130..
Logical_Consistency_Report:
The analytical instruments were calibrated by standard laboratory procedures including: constructing calibration curves, running blank and spiked quality control samples, and analyzing standard reference materials. Each batch of sediment and tissue samples was accompanied by QC analyses consisting of method blanks, matrix spikes, matrix spike duplicates, and standard reference materials (SRMs). In total, approximately 5% of all analyses were QC analyses. Processing quality was considered acceptable if the following criteria were met: blanks were less than three times the minimum detection limit; accuracy, as determined by analysis of certified reference materials, was within 30% for organic analytes and within 15% for inorganic analytes; and precision, as determined by replicate analyses, was within 30% for organic analytes and within 15% for inorganic analytes. Additional specifications and guidelines are presented in Valente and Strobel (1993).
Completeness_Report: At the current time, the Analyte and Site are complete.

Process_Description:
Data Acquisition:The sample collection methods used by NOAA and NOAA contractor field crews will be described here.Sampling Objective:Bivalve mollusks are collected for the analysis of trace element and organic chemical constituents. Separate samples from the same site are packaged for organic analyses, trace element analyses, and gonadal index and histopathology analyses. Once on approximately a decadal basis sediment samples are collected from corresponding Mussel Watch bivalve sites. When the core bivalve sites were first established three collections (stations) and subsequent analyses were performed for each site. Likewise three sediment stations were established for each site. Samples from the same sediment site are collected for sediment grain-size analyses.Bivalve Collection Methods Summary Mollusks are collected at marine sites in the months of November-March with each site visited within three weeks days of a prescribed date. In the Great Lakes, collections are made in late August or early September. From 1986 to 1991, six separate composite samples of 20 oysters or 30 mussels were collected at each site. The small size of Dreissena spp. requires that composite samples from the Great Lake sites consisted of up to 100 individuals. Three composites are homogenized for trace element analyses and three for trace organic analyses. That protocol still applies whenever a site is sampled for the first time. Otherwise, since 1992 only two composite samples have been collected; one for organic and one for trace element analysis.The preferred size ranges are 5-8 cm for mussels, 7-10 cm for C. virginica, 2.5-5 cm for O. sandvicensis. Mollusks are not shucked in the field. They are separated when found to be adhering to one another and scrubbed with a nylon or natural fiber brush to remove adhering detritus. Cleaned samples are then packed in ice or dry ice and shipped to the laboratory. Composite samples are prepared by homogenizing the soft parts of 30 mussels or 20 oysters.Sediment Collection Methods Summary:Multiple sediment grabs were collected from each site using a Young-modified Van Veen grab sampler or hand held box corer. Each grab was nominally 440 cm2 in area and up to 10 cm in depth, but only the top two to three centimeter section of a grab was retained for the chemical analyses. Multiple grabs were processed until sufficient sediment were collected. Any large organisms encountered were removed, but otherwise the sample included resident organisms. Sediment samples were separated into two fractions for storage until analysis. One fraction was frozen and used in the chemical analysis reported in this file, and for the total organic carbon and percent moisture parameters reported in the LAB file. Sampling Platform: Samples were collected from gasoline powered boats, 13 to 24 feet in length or directly from shore for intertidal sites. Sampling Equipment :A 1/25 m2, stainless steel Young-modified Van Veen grab sampler or a hand held box corer was used to collect sediments. Intertidal mussels and oysters found in shallow environments were collected by hand. Subtidal mussels and oysters were collected with an oyster dredge or hand held tongs. Zebra mussels in the Great Lakes were collected by hand while snorkeling or with with an epi-benthic dredge towed from a gasoline powered boat. Sample Collection: Calibration: The sampling gear does not require any calibration, although it was inspected daily for wear and damage.Sample Collection: Quality Control: Care was taken to minimize disturbance to the sediment grabs. Grabs that were incomplete, slumped, less than 7 cm in depth, or comprised chiefly of shelly substrates were discarded. The chance of sampling the same location was minimized by repositioning the boat (five meters downstream) after three sampling attempts.Sample Collection: ReferencesO'Connor, T. P. and G. G.

Data Preparation and Sample Processing:Sample Processing Objective:Sediment and tissue samples were analyzed for metals, butyltins, PAHs, PCBs, PBDEs and organochlorine-pesticides.Methods Summary:All samples from the Gulf of Mexico Coast collected from 1986 to 1999 were analyzed by scientists from the Geochemical and Environmental Research Group or the Department of Oceanography at Texas A&M University (TAMU) in College Station, TX. For 1986-1988, samples from California and Hawaii were analyzed by Scientific Applications International Corporation in LaJolla, CA. For 1986-1994 all other West Coast samples and all East Coast samples were analyzed by scientists from the Battelle Laboratories in Duxbury, MA and Sequim, WA. For 1994-1999 all samples from all coasts were analyzed by the Geochemical and Environmental Research Group of the Department of Oceanography at Texas A&M University in College Station, TX. Since 2000, all samples have been analyzed by TDI-Brooks in College Station, TX.All laboratories, in all years, have used cold vapor atomic absorption for the analysis of Hg. TDI-Brooks International, Inc who has been performing the analyses since 2000 uses a modified version of EPA method 245.6. At Battelle, analyses for As, Cu, Se, and Zn have been made by X-ray fluorescence and those for Cd, Ni, and Pb by graphite furnace atomic absorption (GFAA). Beginning in 1992, inductively-coupled plasma with mass spectroscopy detection (ICP/MS) was used for Cd, Cr, Ni, and Pb. The analytical instruments used by SAIC and TAMU were GFAA for As, Cd, Ni, Pb, and Se; flame atomic absorption (FAA) for Zn; and both GFAA and FAA for Cu, depending on the concentration present. Since 2000 As and Se have been analyzed by atomic fluorescence spectrometry; As has also been analyzed by ICP-optical emission spectrometry (ICP/OEP). ICP/OEP is also used to determine Cu, Ni and Zn while ICP/MS is used for Cd, Ni and Pb. Digestion procedures prior to elemental analysis varied to some extent among laboratories and years. Prior to 1990, Battelle used concentrated nitric and perchloric acids in aTeflon digestion bomb in a conventional oven. Since 1991, samples have been digested in nitric acid only, and heating has been by microwave irradiation. SAIC used conventional ovens and nitric acid. The Texas A&M Laboratory used nitric and perchloric acids with heating in a conventional oven. From 1991 to 1999, only nitric acid was used. The current analytical laboratory sequentially adds nitric acid and hydrogen peroxide to Teflon bombs to achieve sample dissolution of all but Hg samples.Organic chemical extractions were similar among laboratories. After addition of internal standards and anhydrous sodium sulfate, the tissue was extracted three times with dichloromethane using a tissumizer. After concentration by solvent evaporation and exchange of dichloromethane with hexane, the tissue extract was fractionated by alumina:silica chromatography. The aromatic fraction eluted from the column with 1:1 pentane: dichloromethane was further purified by removing lipids through chromatography on a Sephadex column. Since 1988, this purification has been accomplished via an HPLC procedure. Organic sample extraction since 2000 remains similar to that of previous years but Hydromatrix is used to dry tissue samples and dichloromethane is the only solvent used in accelerated solvent extractor cells. Extracts are purified using alumina/silica gel chromatography followed by high performance liquid chromatography. Purified extracts were chromatographed on 30-m DB-5 fused silica capillary columns. Since 2000, a second column (DB-17HT) has also been used for chlorinated hydrocarbon confirmation. Chlorinated hydrocarbon concentrations were quantified using an electron capture detector (GC-ECD) by all laboratories in all years. For polycyclic aromatic hydrocarbons all analyses by SAIC in 1986-1988 (California and Hawaiian coasts) and those by Battelle in 1986 (East and Northwest Coasts) employed flame ionization detection (GC-FID). Battelle used mass spectrometry detection (GC-MSD) in full-scan mode in 1987. In all other cases the PAH analysis has been by GC-MSD in the selected ion mode (SIM). For butyltin analyses, anhydrous homogenized tissue was extracted with troplone and hexane (East and West Coast samples) or troplone and dichloromethane (Gulf Coast samples). Current methods use either hexane or dichloromethane. The extracts underwent Grignard reactions by addition of hexylmagnesium bromide (Gulf Coast samples) and n-pentyl magnesium bromide (East and West Coast samples). The Gulf Coast method is currently in use for samples from all coasts. Florisil/silica gel or silica alumina column chromatography were used to separate the analytes.Calibration:The analytical instruments were calibrated by standard laboratory procedures including: constructing calibration curves, running blank and spiked quality control samples, and analyzing standard reference materials.Quality Control:Each batch of sediment and tissue samples was accompanied by QC analyses consisting of method blanks, matrix spikes, matrix spike duplicates, and standard reference materials (SRMs). In total, approximately 5% of all analyses were QC analyses. Processing quality was considered acceptable if the following criteria were met: blanks were less than three times the minimum detection limit; accuracy, as determined by analysis of certified reference materials, was within 30% for organic analytes and within 15% for inorganic analytes; and precision, as determined by replicate analyses, was within 30% for organic analytes and within 15% for inorganic analytes. Additional specifications and guidelines are presented in Cantillo and Lauenstein (1998).All laboratories annually participate in annual intercalibration exercise where common samples are analyzed by them, by other laboratories, and by a lead laboratory for the exercise. The lead laboratory for trace element intercalibrations has been the National Research Council of Canada and that for trace organic analysis has been the National Institute of Standards and Technology.
