Known Carcinogen: Chromium and Certain Chromium Compounds   (Site not responding. Last check: 2007-10-24) Chromium is used as an alloying and plating element on metal and plastic substrates for corrosion resistance in chromium- containing and stainless steels and in protective coatings for automotive and equipment accessories. Chromium trioxide is used in chromium plating and in the manufacture of chromated copper arsenate (NCI DCE, 1985c). Chromium (in the form of unidentified chromium compounds) is widely distributed in air, water, soil, and food. www.p2pays.org /ref/03/02845.htm   (2355 words)

Chromium   (Site not responding. Last check: 2007-10-24) Chromium is used as an alloying and plating element on metal and plastic substrates for corrosion resistance in chromium-containing and stainless steels, and in protective coatings for automotive and equipment accessories. Chromium phosphate is slightly soluble in cold water, soluble in acids and alkalies, and insoluble in acetic acid. Hexavalent chromium compounds are corrosive and cause chronic ulceration and perforation of the nasal septum. www.nsc.org /ehc/chemical/chromium.htm   (1646 words)

1998 TRI Data - Top Ten Companies The second largest component of ARMCO/AK’s TRI numbers (5.8 million pounds of the remaining 6.0 million pounds) are the result of the off-site disposal (.55 million) or Off-site transfer (5.2 million pounds) of metal compounds. Chromium, manganese and nickel are prevalent in the steel making industry and are emitted as a particulate. The bulk of the TRI numbers (6,510,000 million pounds of 6,770,000 million pounds) is the offsite transfer of metal compounds (primarily zinc). www.dep.state.pa.us /dep/deputate/pollprev/tri/TRI-companies.htm   (1261 words)

U.S. Patent: 5010152 - Polymerization process utilizing chromium on an acid agglomerated refractory gel - April 23, 1991 When the purpose is to produce a chromium olefin polymerization catalyst the chromium is preferably incorporated by simply utilizing a water soluble chromium compound which is coprecipitated with the refractory material. Chromium is generally present in an amount within the range of 0.001 to 10, preferably 0.1 to 5, more preferably about 1 weight percent based on the weight of the dried gel. Generally where chromium is to be converted to the hexavalent state the chromium-containing xerogel is heated in an oxygen-containing ambient, generally air at a temperature within the range of 300.degree. www.everypatent.com /comp/pat5010152.html   (8844 words)

TRI Explorer Report (COFA) TRI Explorer is using an interim data set that includes revisions submitted to EPA as of August 1, 2001 for the years 1988 to 1999 (i.e., revisions submitted to EPA after this time are not reflected in TRI Explorer reports). Users of TRI information should be aware that TRI data reflect releases and other waste management of chemicals, not exposure of the public to those chemicals. TRI data, in conjunction with other information, can be used as a starting point in evaluating exposures that may result from release and other waste management activities that involve toxic chemicals. www.leanweb.org /maps/ascensio.html   (437 words)

Chromium on mixed metal phosphate base with organoboron cocatalyst - Patent 4481302 A catalyst system according to claim 1 wherein the chromium of said chromium component is present in an amount within the range of 0.1 to 5 weight percent based on the weight of said xerogel base. With chromium on silica olefin polymerization catalysts, it has been found that a more economical route to olefin polymerization is to utilize a slurry system for the polymerization. The chromium compounds are used in amounts sufficient to give 0.001 to 10, preferably 0.1 to 5, more preferably about 1 weight percent chromium based on the weight of the xerogel base. www.freepatentsonline.com /4481302.html   (4840 words)

Feature Article - Chromium Plating Another way to produce microporous chromium is to lightly spray the surface of the chromium deposit with a hard, fine abrasive material such as 60- or 80-mesh alumina, or sand. A major distinction between trivalent chromium processes is the chemistry used to prevent the formation of hexavalent chromium at the anode during plating. The membrane prevents the migrating trivalent chromium ions in the solution from reaching the anode, thus preventing their oxidation to the hexavalent state. www.pfonline.com /articles/pfd0016.html   (3417 words)

JEA - TRI Each year since 1987 more than 23,000 companies have filed TRI reports on their total emissions of more than 600 different chemicals. TRI reports are filed with the Environmental Protection Agency (EPA). Mercury emissions by electric utilities are below TRI reporting requirements--our industry accounts for less than a third of all U.S. industrial mercury emissions--but Florida utilities are currently monitoring and reporting to the EPA under a different program. www.jea.com /community/education/enviroissues/tri.asp   (745 words)

Cobalt-aluminum-phosphorus-silicon-oxide molecular sieves - Patent 4744970 These compositions may be prepared hydrothermally from gels containing reactive compounds of cobalt, aluminum, phosphorus and silicon capable of forming framework tetrahedral oxides, and preferably at least one organic templating agent which functions in part to determine the course of the crystallization mechanism and the structure of the crystalline product. In the foregoing expression of the reaction composition, the reactants are normalized with respect to the total of "w", "x", "y" and "z" such that (w+x+y+z)=1.00 mole, whereas in the examples the reaction mixtures are expressed in terms of molar oxide ratios and may be normalized to the moles of P.sub.2 O.sub.5. This latter form is readily converted to the former form by routine calculations by dividing the number of moles of each component (including the template and water) by the total number of moles of cobalt, aluminum, phosphorus and silicon which results in normalized mole fractions based on total moles of the aforementioned components. www.freepatentsonline.com /4744970.html   (9642 words)

Gain Muscle Weight Without Nitric Oxide I tried fast reps, and I tried super-slow reps. I did 1 exercise per muscle, and I tried 6 different exercises per muscle. The supplement companies themselves say it, but they try to twist it by saying that "they want to ensure the effectiveness of these products and they want to 'help' bodybuilders by producing supplements that work". I am trying to decide whether or not to renew my subscription to Muscle and Fitness and Ironman (just for the pictures, and to laugh at all the useless articles), but why waste the money. www.fromskinnytomuscular.com /google-nitric-oxide.html   (8403 words)

Chromium may reduce risk of diabetes A new study presented at the 57th Annual Scientific Session of the American Diabetes Association Meeting in Boston, on June 23, 1997, demonstrated that daily supplementation with 1,000 micrograms of chromium supplied as chromium picolinate significantly enhanced the action of insulin. Insulin is the master metabolic hormone in our body and regulates blood sugar; chromium is an essential trace mineral required by humans in order for insulin to work properly. Also examined in these subjects (using a sophisticated imaging technique) was the amount of abdominal fat present at the beginning and end of the study. musclelink.net /chromium.html   (637 words)

Toxics Release Inventory (TRI) Form R The 1996 TRI Data Quality Report documents that, for the facilities surveyed, 100% of the stack emission factors derived by SIC 33 facilities were developed by the facilities themselves: no emission factor data was provided by the USEPA, trade associations or from any other source. Aluminum, copper, zinc, nickel, manganese, lead and chromium have been listed as SARA 313 toxic chemicals and these elements may be present in greater than “de minimus” concentrations for a given alloy. However, the aluminum fumes are converted to non-fibrous aluminum oxide so the amount of aluminum fume reported, by these companies, as released to the environment is zero. www.diecasting.org /information/tri   (2663 words)

Sticking PTFE to Frying Pans   (Site not responding. Last check: 2007-10-24) The reason aluminum doesn't rust is that a thin layer of aluminum oxide forms on the surface of the metal. If you blended, copolymerized, or better yet were able to sythesize a block copolymer of TFE with a monomer that would hydrogen bond with the aluminum oxide ie. You could pour a hot homogenous mixutre on the aluminium and upon cooling the mix would microphase seperate with the OH moeity concentrating on the metal surface and the CF migrating away from it. www.pslc.ws /mactest/ptfeidea.htm   (1383 words)
