“…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.…”

“…Extracts of dated core sections for PCB, chlorinated hydrocarbon pesticide, and dioxin analyses were prepared using soxhlet extraction and column chromatography cleanup. Most of the PCB samples were analyzed following procedures previously described by Bopp et al (1). Total PCBs are generally reported as the sum of 18 individual packed column peak components ranging from dichlorobiphenyls through decachlorobiphenyl (2).…”

“…At main-stem Hudson site 1 (Figure 1 (7) and analyzed by a congener-specific method (8) similar to 91-11 (6). Chlorinated hydrocarbon pesticides were analyzed following procedures reported elsewhere (1). Levels of chlordane are reported in terms of y-chlordane, which comprises about 15% of technical chlordane (9) Figure 1).…”

“…Publications resulting from this work [e.g., Bopp et al (1)(2)(3)(4)] have generally focused on a specific location (western NY/NJ harbor, the main stem of the Hudson, Jamaica Bay, etc.) and often on a particular contaminant or group of contaminants (polychlorinated biphenyls [PCBs], dioxins, or trace metals).…”

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.

“…In most samples, the levels of p, p 0 -DDT were much higher than those of o, p 0 -DDT, which is consistent with the technical DDT composition. Generally, technical DDT contains 77.1 % p, p 0 -DDT, 14.9 % o, p 0 -DDT, 4 % p, p 0 -DDE, and \5 % others (Bopp 1982;Zhu et al 2005). The ratio of DDT/(DDD ?…”

The contamination of organochlorine pesticides (OCPs) and hexachlorobutadiene (HCBD) in soils, plants, and terrestrial fauna from a former pesticide-producing area in Southwest China was investigated. High levels of OCP residues (RHCHs and RDDTs of 3.89-13,386 and 23.3-11,186 ng g -1 dw, respectively) were found in the soils within the producing factory, indicating that the former pesticide factory brownfield site poses a high environment risk and that effective soil remediation is needed. The OCP concentrations in soils surrounding the pesticide factory were 1-2 orders of magnitude higher than in the other agricultural areas from China. Grass, vegetables, and tree leaves from the surrounding areas of the point source showed moderate OCP pollution, which was likely to be causing potential negative impacts on terrestrial ecosystem. OCP levels in terrestrial species from the studied area including insects, free-range chickens and birds were moderate, and were generally within accepted safe levels.b-HCH was the most prevalent isomer, implying that hexachlorocyclohexane (HCH) residues were mainly derived from the degradation of technical HCH. The dichlorodiphenyltrichloroethane (DDT) profiles reflected obvious degradation of technical DDT. In the study area, the concentrations of HCBD were \0.02-5.59, 0.03-24.6 ng g -1 dw and 1.65-3.80 ng g -1 lw in soils, plants, and animals, respectively, which were relatively low and not sufficient to cause observable adverse biological effects.

[1] Tropical Storms Irene and Lee in 2011 produced intense precipitation and flooding in the U.S. Northeast, including the Hudson River watershed. Sediment input to the Hudson River was approximately 2.7 megaton, about 5 times the long-term annual average. Rather than the common assumption that sediment is predominantly trapped in the estuary, observations and model results indicate that approximately two thirds of the new sediment remained trapped in the tidal freshwater river more than 1 month after the storms and only about one fifth of the new sediment reached the saline estuary. High sediment concentrations were observed in the estuary, but the model results suggest that this was predominantly due to remobilization of bed sediment. Spatially localized deposits of new and remobilized sediment were consistent with longer term depositional records. The results indicate that tidal rivers can intercept (at least temporarily) delivery of terrigenous sediment to the marine environment during major flow events.
