Title: National Status and Trends: Bioeffects Program - San Francisco Bay Database
Short Name: SFB_metadata
Status: Completed
Publication Date: 2008-05
Abstract:

This study was based on the sediment quality triad (SQT) approach. A stratified probabilistic sampling design was utilized to characterize the San Francisco Bay system in terms of chemical contamination, sediment toxicity (Microtox, amphipod bioassays; sea urchin gamete bioassay; and P450 biomarker) and benthic infaunal community structure. The purpose was to define the extent and magnitude of toxicity and other biological effects associated with contaminants in the San Francisco estuary system from the delta to the south Bay and out to the Golden Gate. This file contains data measured in the San Francisco Bay Estuary in 2000 and 2001. Samples were collected for water and sediment analyses.

Purpose:

Specific objectives of the study were to: 1. Describe the levels and spatial distribution of contaminants in the San Francisco Bay estuary; 2. Describe the incidence, severity and spatial extent of contamination, toxicity, and characteristics of the benthic infaunal community; 3. Describe the study results in relation to known or suspected sources of contamination; 4. Describe statistical relationships between levels of contaminants and adverse biological effects, and identify chemicals of concern in terms of regional environmental quality and adverse biological effects; 5. Compare environmental conditions within sub-areas of San Francisco Bay and compare estimates of toxicity in San Francisco Bay with those in other estuaries based on comparable data. 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 OBJECTIVES: SITE LOCATION - Sampling sites were located by GPS with a manufacturer reported position accuracy of better than 3 meters in DGPS mode. 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 San Francisco Bay Project specify accuracy and precision requirements of 30% for organic analytes and 15% for inorganic analytes in sediment samples. WATER COLUMN MEASUREMENTS - Water column monitoring instrumentation was calibrated based on manufacturer's recommendations (YSI Corporation). Depth was recorded from the vessel fathometer. 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 Site location - Handheld GPS units were compared daily with vessel GPS units. 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. Water column measurements - Fields are arranged as follows:Indicator; QA sample type or measurement; Data generated for measurement quality. DO; Water-saturated air calibration; Difference between probe value and saturation level. Salinity; Seawater standard; Difference between probe measurement and standard value. Specific Conductance; Seawater standard; Difference between probe measurement and standard value. Temperature; Thermometer; +/- 1C.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: 459555
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 Chlorinated benzenes = 1,2,4,5-Tetrachlorobenzene, 1,2,3,4-Tetrachlorobenzene, Pentachlorobenzene, Hexachlorobenzene and PentachloroanisoleTotal Dieldrin = sum of concentrations of two compounds aldrin and dieldrin.Total cyclodines = sum of Heptachlor, Heptachlor Epoxide, Oxychlordane, Alpha Chlordane, Gamma Chlordane, Cis-Nonachlor, Trans-Nonachlor, Aldrin, Dieldrin, Endrin, Endosulfan IITotal HCH = Alpha HCH, Beta HCH, Gamma HCH, Delta HCHTotal 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.High Molecular Weight PAHs = Fluoranthene, Pyrene, Benz(a)anthracene, Chrysene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(e)pyrene, Benzo(a)pyrene, Perylene, Indeno(1,2,3-c,d)pyrene, Dibenzo(a,h)anthracene, Benzo(g,h,i)perylene High Molecular Weight Substituted PAHs = C1-Fluoranthenes/Pyrenes, C1-Chrysenes, C2-Chrysenes, C3-Chrysenes, C4-Chrysenes Low MW PAHs = Naphthalene, Biphenyl Acenaphthylene, Acenaphthene, Fluorene, Anthracene, Phenanthrene, Dibenzothiophene Low Molecular Weight Substituted PAHs = C1-Naphthalenes, C2-Naphthalenes, C3-Naphthalenes, C4-Naphthalenes, C1-Fluorenes, C2-Fluorenes, C3-Fluorenes, C1-Phenanthrenes/Anthracenes, C2-Phenanthrenes/Anthracenes, C3-Phenanthrenes/Anthracenes, C4-Phenanthrenes/Anthracenes, C1-Dibenzothiophenes, C2-Dibenzothiophenes, C3-DibenzothiophenesSeveral 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.
