Background & Aims: Cement industry is very contaminated. Contaminants resulting from industries include dust, carbon compounds, sulfur and nitrogen. The purpose of this study was to evaluate the output of pollutants from cement plants in soil samples and leaf tree species. Methods: This study descriptive-analytic was designed tree species, plants and soil around the plant.
Information on production and production capacities for energy minerals is also available in the country chapters of the USGS Minerals Yearbook.Nonfuel minerals - alphabetical index to publications, contacts, and links to more information
Corium, also called fuel containing material (FCM) or lava-like fuel containing material (LFCM), is a lava-like material created in the core of a nuclear reactor during a meltdown accident.. It consists of a mixture of nuclear fuel, fission products, control rods, structural materials from the affected parts of the reactor, products of their chemical reaction with air, water and steam, and, in ...
Cesium in the Environment. Because Cs-137 bonds with chlorides to make a crystalline powder, it reacts in the environment like table salt (sodium chloride): Cesium moves easily through the air. Cesium dissolves easily in water. Cesium binds strongly to soil and concrete, but …
The Mineral Commodity Summaries publication is part of the core function of the minerals information activities transferred from the U.S. Bureau of Mines to the USGS in 1996. These publications are now the responsibility of the Minerals Information Team (MIT). These publications cover mineral commodities and are published annually.
Inspection Procedures for Construction Sites Using Portland Cement. (April 16, 2007). Instructs OSHA compliance officers not to apply new 29 CFR 1926.1126 for construction site exposures to portland cement. Portland cement is specifically excluded from that standard, even though cement may have trace amounts of chromium (VI).
The Minerals Yearbook is an annual publication that reviews the mineral industry of the United States and foreign countries. It contains statistical data on materials and minerals and includes information on economic and technical trends and developments. The yearbook is published in three volumes: Volume I, Metals and Minerals; Volume II, Area Reports, Domestic; and Volume III, Area Reports ...
weak chemical interaction with the cement matrix [2,3]. Consequently, there are safety and economic incentives for the extraction of uranium, mercury and cesium before subjecting the cemented waste to a stabilization process. The technology for recovering uranium from its most common ores is well established and a

marketing and use of cement and cement-containing preparations: Cement and cement-containing preparations may not be used or placed on the market, if they contain, when hydrated, more than 0.0002% (2 ppm) soluble chromium (VI) of the total dry weight of the cement. 1 Chromate reduction By adding a reducing agent, such as ferrous sulfate, the
Caesium chloride or cesium chloride is the inorganic compound with the formula Cs Cl.This colorless solid is an important source of caesium ions in a variety of niche applications. Its crystal structure forms a major structural type where each caesium ion is coordinated by 8 chlorine ions.
INTRODUCTION. The purpose of this review is to summarize information related to hexavalent chromium, Cr (VI), in the portland cement industry. The catalyst for initiating this project was the content restrictions and labeling/marketing of cements based on the level of Cr (VI) in cement in Europe, and the potential for a similar situation in North America in the near future.

Conclusions: According to the findings of this study, we can conclude that dust subsides the leaves of three species of oak and black Talo and reed which contain considerable concentrations of metals such as silver, barium, bismuth, cesium, chromium, cobalt, cadmium and arsenic. Keywords: Cement, Pollutants, Tree Species, Golestan Province. 1.
Chromium is a member of group 6, of the transition metals. Chromium(0) has an electron configuration of [Ar]3d 5 4s 1, owing to the lower energy of the high spin configuration. Chromium exhibits a wide range of oxidation states, but chromium being ionized into a cation with a positive 3 charge serves as chromium's most stable ionic state.
