In ancient times, the reduction process was carried out by heating PbO in a charcoal fire. Lead melts at 328 °C, so molten lead can easily be separated. Missouri, Idaho, Utah, and Colorado are the largest producers of lead in the United States. Wisconsin and Illinois were formerly important producers as well. In addition to the United States, the largest producers of lead are Australia, Canada, and Russia. [Pg.250]

The first centralized electric generating plant in the United States was Edison s three-unit steam-engine-based station, which suppHed electric power to light approximately 5000 electric lamps in a group of homes and businesses in New York City in 1882. Also in 1882, the first hydroelectric power plant went into operation in Appleton, Wisconsin, generating approximately 25 kW of power, enough to power more than 200 100-watt light bulbs. [Pg.1]

The main maple-symp-producing areas are located in the northeastern and midwestem United States and eastern Canada. In the United States, leading producing states in 1994 were Vermont (accounting for 33% of total production). New York (19%), Maine (11%), and Wisconsin (10%) (55). U.S. production and imports as weU as prices for maple symp are shown in Table 6. Total production in the United States and Canada for 1995 is estimated to be about 25 million kg (57). [Pg.296]

Provides regulator). information for the chemical process industiy. The ChemAlliance site was made possible in large part due to funding provided by the United States Environmental Protection Agency. ChemAlliance is a partnership between the Chemical Industiy, EPA s Office of Enforcement and Compliance Assurance, and the ChemAlliance staff who reside at Michigan Technological University, Pacific Northwest National Laborator)>, and University of Wisconsin. [Pg.308]

Material produced by Ruetgerswerke A. G. is satisfactory. This can be obtained in the United States from Terra Chemicals Inc., New York, New York Aldrich Chemical Co., Milwaukee 10, Wisconsin and K and K Laboratories Inc., Jamaica 33, New York. [Pg.81]

Groundwater has also been surveyed for methyl parathion. In a study of well water in selected California communities, methyl parathion was not detected (detection limit of 5 ppb) in the 54 wells sampled (Maddy et al. 1982), even though the insecticide had been used in the areas studied for over 15 years. An analysis of 358 wells in Wisconsin produced the same negative results (Krill and Sonzogni 1986). In a sampling of California well water for pesticide residues, no methyl parathion was detected in any of the well water samples (California EPA 1995). In a study to determine the residue levels of pesticides in shallow groundwater of the United States, water samples from 1,012 wells and 22 springs were analyzed. Methyl parathion was not detected in any of the water samples (Kolpin et al. 1998). In a study of water from near-surface aquifers in the Midwest, methyl parathion was not detected in any of the water samples from 94 wells that were analyzed for pesticide levels (Kolpin et al. 1995). [Pg.158]

Acrylonitrile is not a common contaminant of typical surface water or groundwater. In a state- wide survey of over 1,700 wells in Wisconsin, acrylonitrile was not detected in any sample (Krill and Sonzogni 1986). Acrylonitrile was detected in 46 of 914 samples of surface water and groundwater taken across the United States (Staples et al. 1985), generally at levels less than 10 ppb. [Pg.85]

If the phase diagram is viewed as a map (as suggested by Ball, 2000), similar to a map of the United States, with the different water phases (solid, liquid, gas) comparable to different states (i.e., Iowa, Illinois, and Wisconsin) and the phase boundaries as the state borders, we can envision... [Pg.13]

This paper is adapted from Chapter II of my Ph.D. dissertation at the University of Wisconsin-Madison, "Synthetic Food Colors in the United States A History Under Regulation" (1982). I wish to thank my major professor, Aaron Ihde, and the other official readers of the dissertation, John Parascandola and Stanley Schultz, for their helpful suggestions for improving the original draft. [Pg.154]

United States, but approximately 80% of it is produced commercially in Wisconsin (Kowalchik and Hylton 1987). [Pg.180]

The first of two stays of the senior author at Iowa State University was supported by a contract between Ae United Nations Industrial Development Organization and Ae National Chemical Laboratory, administered in the United States by the Carl Duisberg Society, Inc. This work was also supported by the Engineering Research Institute of Iowa State University. The authors thank Ron Niece, Cynthia Wadsworth, Nick Strickland, and Tony Grabski of the University of Wisconsin Biotechnology Center for providing confirmation of the amino acid sequence, and Brian Chait and Ron Beavis of Rockefeller University for attempting matrix-assisted laser desorption mass spectroscopy on Ac enzyme. This article is N(X Communication No. 4950. [Pg.424]

Table 4-1 reports the other facilities, besides Dupont, in the United States that produce and/or process 1,3-dinitrobenzene. The data reported in Table 4-1 are derived from the Toxics Release Inventory (TRI) of EPA (TRI92 1994). Only certain types of facilities were required to report to the TRI databank of EPA. Hence, this is not an exhaustive list. The Aldrich Chemical Company (Milwaukee, Wisconsin) and Janssen Chimica (Gardena, California) also produced 1,3-DNB for commercial sale and use (Van et al. 1991). 1,3,5-TNB has been manufactured commercially by Kodak Park Division (Rochester, New York) (OHM/TADS 1991). [Pg.74]

In the United States, the most remarkable lead region—and, according to Booth, probably the largest i n the known world—where the galena is disseminated in beds of greater or less extent, is in Wisconsin, Iowa, Illinois, Missouri, and Kentucky,... [Pg.461]

This chapter demonstrates the usefulness of stable isotopes in investigating groundwater-lake systems. The discussion emphasizes isotopic applications to groundwater-lake systems characteristic of the temperate glaciated regions of the north-central and northeastern United States. Thus, it is also applicable to similar systems in other glaciated parts of the world, such as the Scandinavian peninsula and northern Asia. The applications stem from our experience with lake systems in the lake district of north-central Wisconsin. As such, we restrict our discussion to shallow groundwater systems that are hydraulically connected to freshwater lakes. [Pg.75]

There are very many European localities, including Saxony Bohemia Switzerland Cornwall, in England Spain Sweden Japan and elsewhere, In the United States, sphalerite is found in Arkansas, Iowa, Wisconsin, Illinois, Colorado, New Jersey, Pennsylvania, Ohio, and especially in the area that includes parts of Kansas, Missouri, and Oklahoma. The word sphalerite is derived from the Greek, meaning treacherous, and its older name, blende, meaning blind or deceiving, refers to the fact that it was often mistaken for lead ore. [Pg.1532]
