... ABSTRACT The migration and enrichment of heavy metals have great influence on environment and ecosystem due to the increasing biological toxicity, resulting in serious environmental risk. This paper focuses on the vertical distribution of heavy metals in the water environment system...

... ABSTRACT With the rapid development of economy and the concentrated populations, more and more pollutants entry into the water environment in coastal areas of the Yangtze River Estuary. Field investigations were conducted twice in this study to evaluate the characteristics of heavy metals...

... ABSTRACT Nowadays, heavy metal pollution in seabed silt is becoming more and more serious. In this study, a new disposal method of using dredged sludge mud mixed with quicklime, sand and cement to produce bricks was proposed. Taking the water absorption and compressive strength of unburned...

... by-products such as fly ash (Fa), red mud (Rm), lime (L) and gypsum (G) is proposed and employed. Various mixtures of MDS were prepared with different proportions of Fa-RmLG. The settlement, leaching of heavy metals and the most important property, unconfined compressive strength were evaluated. As a result...

... Abstract This study investigated the influence of a giant tsunami by the earthquake along the Nankai Trough on the benthic environment in terms of heavy-metal pollution in Osaka Bay as a pilot ocean. The high-resolution tsunami-tide and particle tracking simulations demonstrated...

... be better if it could be effectively utilized as a recycled resource. Using ash as a fill material would be most effective because a large amount of it can be disposed at low cost. A series of unconfined compression tests and heavy metal leaching tests were carried out in order to examine the appropriate...

... ABSTRACT A solidification method by cement of dredged sludge has been performed in laboratory during last four years. The treated sludge is partially contaminated by some heavy metals. The objectives of the research program was to treat and reuse the solidified sludge as road or civil...

... of nutrients (silicates, nitrates, nitrites, and phosphates) and heavy metals (Cu, Zn, Pb, Cd) as well as the mineralogical and grain size composition of the discharged sediments were determined on material collected by sediment traps, water bottles, and a multiple corer. Preliminary data on characteristics...

... Our projects within the German research group for deep-sea environmental protection (TUSCH) investigate biogeochemical cycles in the bottom water - deep-sea floor interface and Its possible reactions to technical activities, especially binding and release of heavy metals. During research cruise...
