Title: National Status and Trends: Bioeffects Program - Sabine Lake, Texas Database
Short Name: SAL_metadata
Status: Completed
Publication Date: 2008-05-01
Abstract:

The toxicity of sediments in Sabine Lake, Texas, and adjoining Intracoastal Waterway canals was determined as part of bioeffects assessment studies managed by NOAA's National Status and Trends Program. The study area encompassed all of Sabine Lake, portions of the Sabine River, portions of the Neches River, portions of the Neches-Sabine Canal at the confluence of the two rivers, portions of Sabine Pass channel entrance, and an area in the Gulf of Mexico near the entrance channel. A stratified-random sampling design similar to those used in previous surveys conducted nationwide by NOAA was applied in Sabine Lake. The study area was subdivided into 22 irregular-shaped strata. Strata established within channels were further subdivided into three substrata to improve spatial coverage. Only one location each was sampled within each substratum, whereas three locations were sampled in each of the larger undivided strata.Surficial sediment samples were collected during August, 1995 from 66 randomly-chosen locations. Laboratory toxicity tests were performed as indicators of potential ecotoxicological effects in sediments. A battery of tests was performed to generate information from different phases (components) of the sediments. Tests were selected to represent a range in toxicological endpoints from acute to chronic sublethal responses. Toxicological tests were conducted to measure: reduced survival of adult amphipods exposed to solid-phase sediments; impaired fertilization success and abnormal morphological development in gametes and embryos, respectively, of sea urchins exposed to pore waters; reduced metabolic activity of a marine bioluminescent bacteria exposed to organic solvent extracts; and induction of a cytochrome P-450 reporter gene system in exposures to solvent extracts of the sediments.Chemical analyses were performed on portions of each sample to quantify the concentrations of trace metals, polynuclear aromatic hydrocarbons, and chlorinated organic compounds. Correlation analyses were conducted to determine the relationships between measures of toxicity and concentrations of potentially toxic substances in the samples.The full report is available online at http://www.ccma.nos.noaa.gov/about/coast/nsandt/musselmethods.aspx

Purpose:

Specific objectives of the study were to: (1) the incidence and degree of toxicity of sediments throughout the study area; (2) the spatial patterns (or gradients) in chemical contamination and toxicity, if any, throughout the study area; (3) the spatial extent of chemical contamination and toxicity; (4) the statistical relationships between measures of toxicity and concentrations of chemicals in the sediments. The dataset objective is to report information about chemical residues in sediment, sediment toxicity, and benthic infauna characteristics of the system.

Data Quality

Accuracy:

MEASUREMENT QUALITY OBJECTIVESSite location - Field logistics were conducted aboard the NOAA Ship Ferrell and its launch. Vessel positioning and navigation were aided with a differential-corrected, Global Positioning System (GPS) unit and a compensated LORAN C unit. The two systems generally agreed well when both were operational. Coordinates are expressed in units to the nearest 0.0001 decimal degrees. An acceptable tolerance goal for siting was that the sampling location be established within 0.2nm (+/- 120ft) of the given coordinates. In the event the vessel could not navigate to the site (i.e., too shallow) or the bottom type was not appropriate (i.e., rock or shellfish bed) then the first alternate site was substituted. In the event the first alternate could not be sampled then the second alternate site was sampled. Organic and Inorganic Contaminants - The measurement quality objectives of the Sabine Lake Project specify accuracy and precision requirements of 30% for organic analytes and 15% for inorganic analytes in sediment samples. Water column measurements - Depth was recorded from the vessel's instrumentation to the nearest 0.1 foot.Benthic taxonomy-The minimum acceptable sorting efficiency was 95%. The minimum acceptable taxonomic efficiency was 95%.

Completeness Report:

Data are believed to be complete

Conceptual Consistency:

All chemical contaminant values have been rounded to three significant digits. To accommodate the wide range of values, all concentration values have been formatted to the thousandth unit (0.001). The actual precision is as listed below. Metals, variable ug/g; Butlytins 0.01 ng Sn/g; PAHs 0.1 ng/g; PCBs 0.01 ng/g; Pesticides 0.01 ng/g; DATA QUALITY ASSURANCE PROCEDURES Organic and Inorganic Contaminants - QA procedures include blanks, spiked samples, and standard reference materials with each batch of samples. Any batch failing to meet the specifications presented in Section 9.1 would be reanalyzed or rejected. Benthic taxonomy- At a minimum, 10 percent of all samples were resorted and recounted on a regular basis. Ten percent of samples were randomly selected and re-identified. A voucher collection composed of representative individuals of each species encountered in the project was accumulated and retained.

Process Step 2

CC ID: 456608
Description:

Chemicals with similar structural properties were summed and reported as "Totals" in addition to their individual measured concentrations. The components of these totals are as follows: Total DDT = sum of concentrations of ortho and para forms of parent and metabolites 2,4'DDE; 4,4'DDE; 2,4'DDD; 4,4'DDD; 2,4'DDT and 4,4'DDT. Total Chlordane = sum of concentrations of four compounds alpha-chlordane, trans-nonachlor, heptachlor, heptachlorepoxide. Total Dieldrin = sum of concentrations of two compounds aldrin and dieldrin. Total Butyl tin = sum of concentrations of parent compound and metabolites monobutyltin, dibutyltin, tributyltin, tetrabutyltin [concentrations are in terms of tin]. Total PCB = the sum of the concentrations of eighteen congeners: PCB8, PCB18, PCB28, PCB44, PCB52, PCB66, PCB101, PCB105, PCB118, PCB128, PCB138, PCB153, PCB170, PCB180, PCB187, PCB195, PCB206, and PCB209. Total low molecular weight (lmw) PAHs = sum of concentrations of twelve 2- and 3-ring PAH compounds: naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, biphenyl, 2,6-dimethylnaphthalene, acenaphthene, acenaphthylene, 1,6,7-trimehtylnaphthalene, fluorine, phenanthrene, 1-methylphenanthrene, and anthracene. Total high molecular weight (hmw) PAHs = sum of concentrations of twelve 4-and more-ring PAH compounds: fluoranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluorantene, benzo[k]fluoranthene, benzo[e]pyrene, benzo[a]pyrene, perylene, dibenzathracene, indeno[1,2,3-cd]pyrene, and benzo[ahi]perylene. Total PAH = low molecular weight PAHs plus high molecular weigh PAHs (sum of 24 PAH compound concentrations). Several numerical indices were chosen for analysis and interpretation of the macroinfaunal data. Infaunal abundance is reported as the total number of individuals per station and the total number of individuals per square meter (= density). Taxa richness is reported as the number of taxa represented in a given site location. Taxa diversity, which is often related to the ecological stability and environmental "quality" of the benthos, was estimated by the Shannon-Weiner Index (Shannon and Weaver, 1949). In order to quantify and compare the equitability in the fauna to the taxa diversity for a given area, Pielou's Evenness Index J' (Pielou, 1966) was calculated as J' = H'/lnS, where lnS = H'max, or the maximum possible diversity, when all taxa are represented by the same number of individuals; thus, J' = H' /H' max.
