Item Fish Tissue Sampling Data: 1998-1999(Texas Department of Health, 2000) Texas Seafood Safety DivisionThis document is a compendium of contaminant data for fish and shellfish samples collected by the Seafood Safety Division of the Texas Department of Health (TDH) in calendar years 1998 and 1999. These data have been used to assess the potential health risks from chemical contaminants associated with consuming fish and shellfish from the sampled water bodies. All regulatory decisions made by the Seafood Safety Division are based upon these data. All tissue data are based on laboratory analyses of the edible fillets of fish (skin off) and the edible portions of shellfish. The data tables show the results for all chemical analyses, even if no contaminants were detected. All values are given in wet weight concentration, although some were converted mathematically into wet weight concentrations from dry weight concentrations reported by the laboratory. Each converted value is noted in the appropriate table. Detectable/quantifiable contaminant concentrations are shaded in the data tables. Additional information regarding sampling site locations in this most recent volume of fish tissue data. This includes locator and site maps for each samplings area, a brief verbal description of each sample site, latitude and longitude for each sample site (recorded in the field by Global Positions System (GPS) receiver), and the Texas Natural Resource Conservation Commission (TNRCC) stream segment and sequence in which each site is located. The Texas Department of Health laboratory in Austin analyzed all samples, with the following exceptions. All dioxin and furan analyses were performed by Brehm Research Laboratories at Wright State University in Dayton, Ohio. The USGS laboratory in Denver, Colorado analyzed the Lake Worth and Rio Grande samples. The butyl tin compounds reported for Clear Lake/Galveston Bay were analyzed by the Geochemical and Environmental Research Group at Texas A&M University in College Station, Texas.Item Fish Tissue Sampling Data: 2000-2001(Texas Department of Health, 2002) Texas Seafood Safety DivisionThis book contains contaminant data for fish and shellfish samples collected from Texas waters by the Seafood Safety Division (SSD) of the Texas Department of Health (TDH). With only one exception, the division collected samples in calendar years 2000 and 2001. Samples collected in 1999 from Lavaca Bay (Cox Bay) were inadvertently omitted from 1998-1999 Fish Tissue Data, so are included in this book. Data collected in 2002 from Lake Timpson and Lake Nacogdoches were combined with data collected from these reservoirs in 2000. The Seafood Safety Division collected these samples, with a single exception: the Fort Worth Environmental Management Department (FWEM) and the TDH SSD collected samples from three urban lakes in Fort Worth (Lake Como, Echo Lake, and Fosdic Lake) on different occasions. The Seafood Safety Division uses contaminant data to assess potential health risks from consumption of chemically contaminated fish and shellfish from Texas waters. The Texas Department of Health may, in part, base regulatory decision and consumption advice for fish and shellfish taken from Texas water upon these data. The TDH laboratory in Austin, TX, analyzed all tissue samples for this compilation. Some tissue samples are composites of more than one fish. Each crab tissue samples consists of several crab specimens. TDH analyzed edible fish fillets (skin off) or edible portions of shellfish for numerous contaminants, pesticides, polychlorinated biphenyls, volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCS). The data tables contain results for each chemical (wet weigh concentration) even if the contaminant was not detected. Cells in the tables are shaded to identify detectable/quantifiable contaminant concentrations. For each sampling area, SSD included in this volume maps of locations and sampling sites, and - for those areas with multiple sampling locations - a brief verbal description of each sample location. The book also contains the Texas Commission on Environmental Quality (TCEQ; formerly the TNRCC) stream segment and sequence in which each water body or sampling site is located, along with the latitude and longitude for individual sampling sites (recorded in the field by a global positioning system (GPS) receiver).
