“…The improvement in PCB and chlorinated hydrocarbon levels in sediments along the main stem of the Hudson and in Jamaica Bay and in levels of 2,3,7,8-TCDD in sediments from western NY/NJ harbor have been discussed in detail elsewhere (2)(3)(4)21). These trends reflect the success of efforts to limit inputs of contaminants to natural water systems through restrictions on the use of specific compounds, upgrades of municipal sewage treatment facilities, control of …”

“…A few of the more recent particle samples were suspended matter collected on precombusted quartz fiber filters using a largevolume in situ pumping system (5). Radionuclide analysis of sediment core sections to obtain dating information was performed by nondestructive 'y-ray spectrometry (1)(2)(3)(4). Extracts of dated core sections for PCB, chlorinated hydrocarbon pesticide, and dioxin analyses were prepared using soxhlet extraction and column chromatography cleanup.…”

Analyses of sections from dated sediment cores were used to establish geographic distributions and temporal trends of chlorinated hydrocarbon contaminant levels in sediments from natural waters of the Hudson River basin. Radiometric dating was based primarily on the depth distribution of 137Cs in the cores and on the occurrence of detectable levels of 7Be in surface sediment samples. Eighteen sampling sites included several along the main stem of the Hudson, its major tributaries, and components of the New York/New Jersey (NY/NJ) harbor complex. Drinking-water reservoirs were sampled to place upper limits on atmospheric inputs. Core sections were analyzed for polychlorinated biphenyls (PCBs), 1,1,1-trichloro-2,2-bis(pchlorophenyl)ethane (DDT)-derived compounds, chlordane, and dioxins. Sediment concentrations of most contaminants at most sites have decreased significantly since the mid-1 960s. The data provide a basinwide perspective on major point-source inputs of PCBs to the upper Hudson River and of 2,3,7,8-tetrachlorodibenzo-p-dioxin and DDT to the lower Passaic River. Evidence was found for significant but poorly characterized sources of PCBs and chlordane to the western NY/NJ harbor, and of highly chlorinated dioxins to the upstream sites on the main stem of the Hudson. The results indicate that analysis of dated sediment samples is a most effective and efficient monitoring tool for the study of large-scale geographic and temporal trends in levels of particle-associated contaminants.

“…The LPR has been an effective trap of both sediments and hydrophobic contaminants (Chant et al 2011;Huntley et al 1995;Bopp et al 1991Bopp et al , 1998Chaky 2003).

The fate and transport of hydrophobic organic chemicals (HOCs) is particularly complex in estuaries because of bidirectional longitudinal currents, density stratification, the tendency to trap sediments, and significant dilution in the downstream bay or ocean. Investigations of HOCs in estuaries are further complicated because HOCs typically enter from multiple sources. The distribution of contaminants in estuarine sediment beds reflect a time integration of a complex balance of time-and space-variable fate and transport processes and loading history. A unique opportunity to study HOC fate and transport exists in the Lower Passaic River (LPR), where a pesticide manufacturer was the dominant source of 2, 3,7,3,7, to the estuary and the distribution of this "tracer of opportunity" provides insights about fate and transport processes in estuarine systems. This paper presents observed sediment 2,3,7,8-TCDD patterns within the LPR and the adjacent Newark Bay, and interprets them in terms of fate and transport processes that likely distributed the contaminant from its dominant source, drawing upon other physical datasets as needed. Major observations include that estuarine transport processes have distributed 2,3,7,8-TCDD approximately 18 km upstream of the source and downstream across Newark Bay, and that, generally, HOC trapping processes within the LPR have been highly effective, particularly near the 2,3,7,8-TCDD source and in downstream areas. The present LPR surface sediment 2,3,7,8-TCDD distribution indicates spatially variable recovery, which appears broadly driven by historical net sedimentation patterns, though the dominant processes may be shifting as the system continues to evolve.

“…Special concern has been raised since the 1960s about the environmental persistence, bioaccumulative capacity and toxicity of dioxins and related compounds (DRCs), such as polychlorinated dibenzo-pdioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), as well as non-ortho and mono-ortho polychlorinated biphenyls (dioxin-like PCBs) (Bopp et al, 1991;Cleemann et al, 2000). DRCs constitute a group of polyhalogenated aromatic hydrocarbons that have similarities from the structural, chemical and toxicological point of view (McDonald et al, 1994).…”

• Dioxin-like PCBs accounted for over 83% of the total TEQ for all cetaceans • Negative correlations were found between length and TEQ values in franciscanas.• PCB concentrations found are among the highest ever reported for cetaceans. a b s t r a c t a r t i c l e i n f o Blubber samples from three delphinid species (false killer whale, Guiana and rough-toothed dolphin), as well as liver samples from franciscana dolphins were analyzed for dioxins and related compounds (DRCs). Samples were collected from 35 cetaceans stranded or incidentally captured in a highly industrialized and urbanized area (Southeast and Southern Brazilian regions). Dioxin-like PCBs accounted for over 83% of the total TEQ for all cetaceans. Non-ortho coplanar PCBs, for franciscanas (82%), and mono-ortho PCBs (up to 80%), for delphinids, constituted the groups of highest contribution to total TEQ. Regarding franciscana dolphins, significant negative correlations were found between total length (TL) and three variables, ΣTEQ-DRCs, ΣTEQ-PCDF and ΣTEQ non-ortho PCB. An increasing efficiency of the detoxifying activity with the growth of the animal may be a plausible explanation for these findings. This hypothesis is reinforced by the significant negative correlation found between TL and PCB126/PCB169 concentration ratio. DRC concentrations (ng/g lipids) varied from 36 to 3006, for franciscana dolphins, as well as from 356 to 30,776, for delphinids. The sum of dioxin-like and indicator PCBs varied from 34,662 to 279,407 ng/g lipids, for Guiana dolphins from Rio de Janeiro state, which are among the highest PCB concentrations ever reported for cetaceans. The high concentrations found in our study raise concern not only on the conservation of Brazilian coastal cetaceans, but also on the possibility of human health problem due to consumption of fish from Brazilian estuaries.
