Description:

Abstract:

This project assesses chemical contaminant status in sediment and coral tissues (Porites astroides) collected in and around Guanica Bay, Puerto Rico in 2009. Parameters monitored include sediment and coral tissue chemistry for over 100 organic and inorganic contaminants; and Clostridium perfringens (pathogen) concentrations. NOAA's National Status and Trends program regularly quantifies PAHs, PCBs, chlorinated pesticides including DDT and its metabolites, TBT and its metabolites, and trace elements nationwide.

Purpose:

The main objectives of this project were to assess the spatial variability in contaminant concentrations in and around Guanica Bay in around to identify any pollution hotspots and to establish a baseline against which future change can be measured.

Supplemental_Information:

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 butyltin data and in ng/dry g for everything else. The latitude and longitude is measured using datum NAD83. The QA/QC file including Procedural Blanks, Duplicates, Matrix Spikes, Matrix Spike Duplicates and Standard Reference Materials (SRMs) are available upon request.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The measurement quality objectives of NS&T 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).

Process_Description:

Data Acquisition:The sample collection methods used by NOAA and NOAA contractor field crews will be described here.Sampling Objective:Coral tissue samples (Porites astroides) are collected for the analysis of trace element and organic chemical constituents. Samples are collected with a titanium punch and hammer; the punch is cleaned with acetone between sites to prevent contamination between sites. Following sampling, samples are placed in pre-cleaned glass jars, then packed in ice or dry ice and shipped to the laboratory. Sediment Collection Methods Summary:Multiple sediment grabs were collected from each site using a ponar grab sampler. 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. Sampling Platform: Samples were collected from a gasoline powered boats (Aquanauta). Sampling Equipment: A 1/25 m2, stainless steel Young-modified Van Veen grab sampler was used to collect sediments. 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: References Apeti, D.A., S.I. Hartwell, W.E.

Process_Description:

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 organic samples were analyzed by scientists from TDI-Brooks in College Station, TX. Cold vapor atomic absorption for the analysis of Hg using a modified version of EPA method 245.6. Inorganic analyses were performed by scientists at the Trace Element Research Lab (TERL) at Texas A&M University (TAMU). The analytical instruments used by 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. The current analytical laboratory digestion process for inorganics sequentially adds nitric acid and hydrogen peroxide to Teflon bombs to achieve sample dissolution of all but Hg samples. Organic chemical extractions consisted of three extractions 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. 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). For polycyclic aromatic hydrocarbons analysis has been by GC-MSD in the selected ion mode (SIM). For butyltin analyses, anhydrous homogenized tissue was extracted with either hexane or dichloromethane. The extracts underwent Grignard reactions by addition of hexylmagnesium bromide. 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.
