Waste cement is a construction and demolition waste produced from old buildings' demolition and transformation. In recent years, the recycling of recycled concrete is limited to the use of recycled aggregate, and the research on the utilization of waste cement in waste concrete is scarce. This study explored the effective appliion of waste cement for the adsorption of cadmium (Cd2+) from ...
Crushing, bagging, and transportation of limestone increase the risk of chemical spread over a large area. It triggers a variety of problems, especially for soil and vegetation, because of its alkaline nature. Cement production plants are now considered a major source of metal pollution in the environment. They emit organic and inorganic chemicals in the form of metals and metalloids like Cu ...

Cadmium, zinc, copper and metallothionein levels in . 198871 The cadmium levels were low in the range of to μg/g. The concentration of metallothionein determined by the Hgmethod was high (– μmol Hg/g); it was mainly a Znthionein. The percentage of hepatic zinc bound in the MTfraction increased with the overall content of

Objective: The aim of this study was to show whether local appliion of cadmiumimpregnated bone cement can induce apoptosis and decrease the viability of residual osteosarcoma (OS) cells in nude mice. Methods: K7M2 tumorigenic OS cell line was cultivated in vitro. The xenograft tumor model was formed by subcutaneously adding the tumor cells to athymic nude mice.
wood), cement, and phosphate fertilizers. In these products, the presence of cadmium generally does not affect performance; rather, it is regarded as an environmental concern (International Cadmium Association, 2011). Cadmium is also produced from recycled materials (such as Ni– Cd batteries and manufacturing scrap) and some 121. IARC MONOGRAPHS – 100C residues ( cadmium .
Cementbased and pozzolanbased materials are mainly agents in S/S technology [58]. Recently, more rehavesearches been made on the of waste by magnesium potassium S/S phosphate cement (MKPC). MKPC, a ceramic matrix of magnesium potassium phosphate hydrate, has excellent densifiion and mechanical properties, such as reduced leach ability, higher propensity for binding with waste .
