“…1). Due to chronic pollution (e.g., chemical discharges from industrial facilities and sewage treatment plants), the water quality of the NY/NJ Harbor Estuary has been severely degraded for more than a century (Crawford et al, 1994). The highest levels of some chemical pollutants occur in tributaries of AK (Weis et al, 2001).…”

Intracellular partitioning of trace metals is critical to metal tolerance in aquatic organisms and may also influence metal trophic transfer in ecosystems. In this study, we tested the relevance of metal (Cd, Cu, Pb, and Zn) intracellular partitioning in prey as an indicator of metal trophic availability to benthic forage fish, mummichogs (Fundulus heteroclitus), in chronically metal-polluted salt marshes in New York, USA. Two common prey of mummichogs in the study area, Palaemonetes pugio and Nereis acuminata, generally stored increasingly higher proportions of non-essential metals (particularly Pb) in insoluble (less trophically available) cellular components, as the whole body burdens increased. In contrast, intracellular partitioning of essential metals (Cu and Zn) in invertebrate prey varied relatively little among sites. Differential Cd and Pb intracellular partitioning patterns within P. pugio among sites were significantly associated with Cd and Pb whole body burdens in mummichogs, respectively (i.e., prey-driven bioreduction of metals), while bioaccumulation of Cu and Zn in mummichogs was similar among populations. The findings in this study suggest that metal intracellular partitioning within prey may be partially responsible for metal trophic availability to a predator in metal-polluted habitats, while there was also evidence that some predator-dependent processes may offset differential trophic availabilities from prey.

Ecological municipal solid waste (MSW) treatment systems are complex systems engineering concerning with multiple objectives and hierarchical levels. By combining an extension method with fuzzy logic theory, this paper investigated key technologies required by the comprehensive evaluation of ecological health. The method includes the construction of an evaluation system, quantification of evaluation indices, development of a matter-element model, development of an extension evaluation method, and assignment of a blended weight that combines subjectively and objectively estimated weights. This approach was used to develop a comprehensive model for evaluating the ecological health of an ecological treatment system for MSW. The model was then applied to a case study, and the results demonstrated that the model is a reasonable and effective.

“…While it has been reported that oxygen concentrations in the Hackensack River regularly fall below the New Jersey Department of Environmental Protection's water quality criterion (4.0 mg/L) and U.S. Environmental Protection Agency's protective minimum oxygen concentration (2.3 mg/L) for adult fishes [11], DO of water samples collected from the Newark Bay Estuary in summer 2015 and 2016 ranged approximately from 3 mg/L to 9 mg/L, which is above hypoxia ( Table 1). The water quality data are consistent with improved water quality in the Hudson Raritan Estuary (HRE) since the enactment of the 1972 Clean Water Act [5,34]. However, some aquatic species can still be negatively affected by DO level as low as 3-4 ppm [35].…”

“…Sampling of publicly owned treatment works (POTWs), combined sewer overflows (CSOs) and storm water outfalls (SWOs) in the NY-NJ Harbor from 2000 to 2004 reported the presence of toxic heavy metals such as Cd, Pb, and Hg in the effluents, with typically the largest loads of the contaminants found in the effluents from the POTWs because of the volume of their discharge [32]. The elevated concentrations of heavy metals (arsenic, cadmium, copper, chromium, lead, mercury, nickel and zinc) in the Newark Bay Estuary has been reported, which currently pose a potential threat to the aquatic community [5,10,11]. For example, analysis of sediment cores taken from the tidal portion of the Passaic River during the early 1990s Rice et al (1999) reported trace element concentrations in 541 streambed-sediment samples (<63 µm size fraction; silt and clay) collected from 20 study areas across the contiguous United States [46].…”

“…The urban estuary is located in the heavily industrialized and densely populated New York-Newark-Jersey City metropolitan area. Historically, the coastal and marine waters of the estuary were known to support diverse populations of fish and shellfish, but the metropolitan region surrounding the urban estuary has been heavily impacted by both industrial and municipal activities [5]. During the 19th and 20th centuries, factories dumped large quantities of untreated waste into the lower portion of the Passaic and Hackensack Rivers to Newark Bay, which has left hotspots of toxic contaminants throughout the estuary's ecosystem [6,7].…”

Nutrients and Heavy Metals Contamination in an Urban Estuary of Northern New Jersey

Abstract:The Newark Bay Estuary in northern New Jersey contains one of the largest urban wetland complexes in the United States, but the majority of the wetlands and habitats have been lost due to urbanization and industrialization. Field and laboratory research was conducted to understand the impacts of human activities on the biogeochemistry of nutrients and heavy metals in the urban estuary. Concentrations of dissolved nutrients such as nitrate, ammonia, and phosphate were higher in the Hackensack River than in the Passaic River or the Newark Bay, while the Hackensack River was more deficient in dissolved oxygen. Sediment oxygen demand and mobilization of nutrients were higher in sediments with higher organic matter content as a result of microbial decomposition of organic matter. Heavy metals (Cr, Cu, Pb, and Zn) and organic matter were more enriched in finer sediment grains such as silt and clay. There were positive correlations among heavy metals as well as organic matter in sediments. The results suggest that fine grained sediments, which can be readily suspended and transported during tidal cycles, may play a significant role in biogeochemical cycling of nutrients and heavy metals in the urban estuary. It appears that the current sources of nutrients and heavy metals in the water and sediment of the Newark Bay Estuary are mainly domestic effluents from sewage treatment plants during non-storm periods as well as combined sewer overflows during storm events, but further research including more frequent and pervasive water and sediment quality monitoring during dry and wet periods is needed.
