“…In a similar study of Hudson River sediments, , '-DDD analysis of two separate portions of 14 sediment samples yielded an average coefficient of variation of 5.2% (14). PCDD and polychlorinated dibenzofuran analysis was based on GC-MS procedures employed at the University of Nebraska (15) and validated in several interlaboratory comparison studies (16)(17)(18). Acid treatment of samples prior to extraction (19) was found to improve recovery of the 13C-labeled internal standards to 70 ± 10% for 2.3.7.8-TCDD, 90 ± 10% for OCDD, and 60 ± 10% for 2.3.7.8-TCDF.…”

“…In-* Present address during sabbatical leave: Woods Hole Oceanographic Institution, Department of Biology, Woods Hole, MA 02543. creased levels of TBT in water, sediment, and biota have been linked primarily to boating activities. In the water column, TBT residues were reported to lie in the high nanograms per liter range for seawater marinas, and in the low to medium nanograms per liter range for open water (9,(15)(16)(17)(18)(19). TBT residues in the sediments were found to be considerably higher, typically in the range of ~200-1000 iig/kg (15)(16)(17), with decreasing levels with depth (20).…”

“…To date, little is known about the occurrence, temporal variation, and behavior of organotin compounds in freshwater systems (15)(16)(17), especially in respect to phenyltins. The purpose of this study was to determine the presence, partitioning, and fate of phenyltins and butyltins in different compartments of freshwater marinas and detect and monitor seasonal variations and trends throughout 1988-1990.…”

Tetrachlorodibenzo-p-dioxin (2,3,7, was measured in sediments and suspended matter samples from estuaries adjacent to an industrial site in Newark, NJ, where chlorinated phenols had been produced. Present day and recent historical levels of 2,3,7,8-TCDD contamination were established through the use of radionuclide time tracers (7Be, 137Cs). Concentrations up to 21000 parts per trillion (ppt) were found in sediments deposited near the site. Pre-1950 production of DDT at the same industrial site provided another sensitive pollutant source tracer. The total deposition of 2,3,7,8-TCDD in Newark Bay sediments since the late 1940s has been approximately 4-8 kg, among the largest releases documented to date. Sediments dredged from estuaries in this region have been disposed of on land surrounding Newark Bay and at a coastal ocean dumpsite.

“…Samples were extracted and the extracts were cleaned up in accord with the USEPA guidelines for the analysis of PCDOs; detailed descriptions were reported elsewhere [27,28]. Briefly, after spiking 13C-Iabeled PCDO internal standards into samples, dioxins were solvent extracted by using a Soxhlet apparatus, and the extract was submitted to an acid/base wash and fractionated by using a multicolumn liquid chromatographic technique prior to GC/MS analysis.…”

A capillary column gas chromatographic/high resolution mass spectrometric method was developed for the determination of monobromopolychlorodibenzo-p-dioxins (BPCDDs) in environmental samples. The mass spectrometer was operated at high resolution (> 10,000) in the selected ion monitoring mode with magnet switching among tetra through octa groups to achieve low or subpicogram detection limits. Standard BPCDDs (tetracongener through octacongener groups) were utilized to measure accurately the mass spectrometric relative response factors for these compounds, and linear calibrations were achieved by using these standard compounds at different concentrations. The method detection limit is low or sub-parts-per-trillion levels for BPCDDs, the accuracy better than 80% and the precision better than ± 10%. Quantification of BPCDDs and preliminary identification of some specific BPCDD isomers in fly ash samples are also reported.
