backgrounds and objectives:today, one of the most important environmental issues is solid waste produced in dentistry that because of the presence of hazardous, toxic and pathogen agents has special importance. in this survey, solid waste produced in hamadan dentistry laboratories and practical dentist offices is studied.materials and methods: in this descriptive study, from 24 dentistry labora...
In this review, we provide a perspective on the science and technology of vitrification waste. First, background general classes wastes for which is currently used immobilization or proposed, including nuclear industrial hazardous wastes. Next, summarize issues surrounding solubility waste ions resulting uncontrolled crystallization phase separation. Some newer form designs propose controlled c...
899 The Hanford Site is 1517 km2 (586 mi2) in size, located in a sparsely populated area in the rain shadow of the Cascade Mountains, adjacent to the Columbia River in southeastern Washington State (Fig. 1). The Hanford Site was set aside in the early 1940s by the U.S. Government to perform a top-secret mission, the Manhattan Project, for production of plutonium for atomic weapons used to end W...
The later sections (6-9) deal with a few aspects of more direct environmental concern as sociated with nuclear-generated electricity. Topics will be dealt with briefly, or omitted entirely. On issues such as the likelihood of major reactor accidents long-term availability of assured fuel supply, adequate containment of wastes, and the real costs of nuclear-generated power, our lack of input ind...
New methods for the reduction and remediation of hazardous wastes like carcinogenic organic solvents, toxic materials, and nuclear contamination are vital to environmental health. Procedures for effective waste reduction, detection, and removal are important components of any such methods. Toward this end, polymeric smart materials are finding useful applications. Polymer-bound smart catalysts ...

Abstract—The contamination of significant quantities of soils and sediments with uranium and other actinide elements as a result of nuclear activity poses many environmental risks. The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a ...
