... Randle Reef is an area of severely contaminated sediment located in Hamilton Harbour at the western end of Lake Ontario in Canada. The Randle Reef Sediment Remediation Project work area consists of approximately 60 ha of the harbour bottom that are severely contaminated with polycyclic aromatic...

... Eutrophication and contaminated sediments are preoccupying issues in aquatic ecosystems and water resources protection. Saint-Augustin Lake (Quebec, Canada) is affected by both problems (eutrophication and contaminated sediment) and the presence of de-icing salts. According to sustainable...

... of 1.0 VDC/cm was optimal for the approximately 70 % removal of the initial contamination. The reason for the remaining mercury in the sediment could be the presence of CaO, other metals, and organic compounds. electrokinetic remediation contaminated sediments mercury tailing dam gold mine...

... The Taranto harbor area is included in the Italian National Priority List of contaminated sites. For the enlargement works of the fourth quay in the Taranto harbor, the remediation of contaminated sediments shall be carried out. The existing jetty was devoted to unloading of iron ore...

... Solutions to heavy metal-contaminated sediment require the understanding of the availability of heavy metals, interaction of the contaminants with soil and sediment particles, and metal retention mechanisms, which are complicated phenomena. The objective of this investigation was to study...

... This paper describes the lasting effect of sand capping techniques on nutrient release reduction from contaminated sediments. Bottom sediments in Tokyo Bay are very contaminated as the results of eutrophication behavior. From the sediments, a large amount of nutrients are released into seawater...

... In this paper, an in situ bioremediation method is proposed for dioxin contaminated sediments and its efficiency is assessed in laboratory tests including microbial analysis. The main outcomes of this research are (1) Proposal of an in situ bioremediation method using anaerobic micro-organisms...

... The upper section of the Saguenay Fjord was impacted by a catastrophic flood in July 1996. Contaminated sediments were capped by a layer of clean silty post-glacial sediments with background levels of trace metals and polycyclic aromatic hydrocarbons (PAHs). The capping layer was characterized...

.... The environmental concern associated with the harbour can be best viewed as a historical contaminated sediment problem. Approximately 90 000 m 3 of sediment located in Port Hope Harbour's turning basin and west slip are contaminated by uranium and thorium series radionuclides, heavy metals, and PCBs...

... A test method was developed to assess the toxicity of freshwater dredged sediments. Toxicity of contaminated sediments was detected by monitoring survival and growth of fathead minnows ( Pimephales promelas ), emergence and egg hatchability of midges ( Paratanytarsus parthenogenica ), survival...
