This study examines the effectiveness of remediating a well-recognized case of heavy metal pollution at Foundry Cove (FC), Hudson River, New York. This tidal freshwater marsh was polluted with battery-factory wastes (1953-1979) and dredged in 1994-1995. Eight years after remediation, dissolved and particulate metals (Cd, Co, Cu, Pb, Ni, and Ag) were found to be lower than levels in the lower Hu...

In the long term, the main source of contaminants in the Housatonic River is the bottom sediments (both those in the river and in the floodplain). In this long term, environmental conditions will change with time and will be different than they are at present, especially because of and after remediation. For purposes of predicting water quality, it is therefore essential to accurately determine...

This study was designed to assess whether the removal of endocrine disrupting chemicals (EDCs) and other substances from a Waste Water Treatment Works (WWTW) effluent (receiving water: R. Ray, Swindon, UK) by granular activated carbon (GAC) affected biomarkers of exposure to EDCs [vitellogenin (VTG) and spiggin] in male and female three-spined sticklebacks in the receiving water. A nearby river...

Bacteria exhibit the ability to metabolize a wide array of contaminants and, as a result, reduce their toxicity to wildlife and humans. The general goal of this project was to design and evaluate, as a proof-of concept, a DNA microarray assay to evaluate bacterial detoxification mechanisms in contaminated sediments. The assay consists of 100 probes that measure activity of bacterial remediation...

Abstract The purpose of this research was to evaluate the potential plant-immobilized bacterial cells synergism for enhanced remediation polluted river water. water sample collected from Kalyani river, Uttarakhand, India and characterized by high concentration COD (1010 mg/l), BOD (230 NO3−-N (30 PO43−-P (48.9 Pb (1.028 mg/l). This treated on a lab scale with immobilized Epipremnum aureum in va...

Self-healing, one of the four key properties characterizing Autonomic Systems, aims to enable large-scale software systems delivering complex services on a 24/7 basis to meet their goals without any human intervention. Achieving self-healing requires the elicitation and maintenance of domain knowledge in the form of 〈service failure diagnosis, remediation strategy〉 patterns, a task which can be...

The Yellow River Delta (YRD) is an important agricultural and ecological base that is being threatened by crude oil contamination. The remediation of the YRD can be potentially assisted by biosurfactants. Three native unknown biosurfactant-producing bacteria have been isolated (L1, L2, L3). In this paper, we measured the emulsification properties of the three biosurfactants in terms of emulsifi...

Approaches to cognitive remediation have differed across studies. Most of the larger studies have concentrated on group treatments designed without the benefit of recent laboratory-based studies. The current study describes a randomized trial of an intensive cognitive remediation program involving individual daily sessions of 1 hour for up to 3 months. It targets executive functioning deficits ...

An important motivation for the implementation of the Water Framework Directive is the creation of non-market environmental benefits, such as improved ecological quality, or greater opportunities for open-access river recreation via microbial pollution remediation. Pollution sources impacting on ecological or recreational water quality may be uncorrelated, but non-market benefits arising from r...
