  • Nitric Oxide.Vp
    CHAPTER 5 Maple Leaf Foods, Toronto, Canada Brown Foundation Institute of Molecular Medicine, The University of Texas Health Science Center, Houston, TX 77030 ESPITE the many published reports on the beneficial properties of Dnitrite and nitrate in physiology, nitrite and nitrate in cured and pro- cessed meats continues to be perceived as harmful. The previous chapter revealed that certain foods, particularly green leafy vegetables are natu- rally enriched in nitrite and nitrate from growing in soil. However, en- riching meats with nitrite or nitrate during curing is perceived as harmful and advocated by some groups to be eliminated completely. The use of pure sodium nitrate in curing is now only a minor practice in the United States. The ingoing levels of sodium nitrite have been tightly controlled by the Food Safety and Inspection Service (FSIS) of the U.S. Depart- ment of Agriculture. To satisfy consumer demands for no added nitrite processed meats, efforts have recently been taken to creatively adjust the meat curing process by employing “nitrite free” organic vegetable pow- ders instead of directly adding sodium nitrite salts. Although the end re- sult is production of nitrite from the nitrate contained in the vegetable powders, a more “natural” or “organic” approach seems to appeal to con- sumers. This is primarily due to the public perception of nitrite and ni- trate. Reports about methemoglobinemia in infants (blue baby syndrome) caused by drinks or food prepared with nitrate-rich (and bac- terially contaminated) well water and vegetables, intentional and occu- pational intoxications in adults, increasing nitrate levels in soil and lakes as a result of fertilizer overuse, and the formation of potentially carcino- genic N-nitrosamines all contribute to the negative image that nitrite and nitrate have held in recent years.

  • Toxicological Profile for Cyanide
    CYANIDE 141 5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.1 PRODUCTION The demand for hydrogen cyanide in the United States during 2000 was 1.615 billion pounds, up slightly from 1.605 billion pounds in 1999 (CMR 2001). Production of hydrogen cyanide in 2003 was 2.019 billion pounds in the United States (FAS 2005). The demand for hydrogen cyanide was projected to be 1.838 billion pounds in 2004 (CMR 2001; NYSDOH 2005). Major producers of hydrogen cyanide are Adisseo USA, Inc. (Institute, West Virginia); Cyanco Co. (Winnemucca, Nevada); Cytec Industries (Waggoman, Louisiana); Degussa Corp.

(Orange, Texas and Victoria, Texas); Rhom and Haas Texas Inc. (Deer Park, Texas); Solutia, Inc. (Alvin, Texas); Sterling Chemicals, Inc. (Texas City, Texas); and Syngenta Crop Protection (St. Garbiel, Louisiana) (SRI 2005). The combined annual production capacity of these plants is approximately 2.036 billion pounds (SRI 2005). As of February 2005, the following companies produced other cyanide compounds in the United States (SRI 2005): ammonium Crompton, Taft, Louisiana; and Mallinckrodt, Inc., St. Louis, Missouri thiocyanate: cyanogen: Matheson Gas Products, Inc., Gloucester, Massachusetts potassium cyanide: DuPont Chemical Company, Memphis, Tennessee; and The Dow Chemical Company, Nashua, New Hampshire potassium silver Engelhard Corporation, Union, New Jersey; and Metalor Technologies USA, North cyanide: Attleboro, Massachusetts Facilities in the United States producing sodium cyanide and their annual capacity (in millions of pounds) in 2005 include: Cyanco Co., Winnemucca, Nevada (86); and E.I.

    CYANIDE AND CYANIDE COMPLEXES IN THE GOLD- MINE POLLUTED LAND IN THE EAST AND CENTRAL RAND GOLDFIELDS, SOUTH AFRICA. Elysee Bakatula Nsimba (0700692R) A dissertation submitted to the faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2009 CHAPTER ONE ─ INTRODUCTION 1.1 The history of mining on the Witwatersrand Basin The metropolis of Johannesburg, South Africa’s largest city and financial centre, owes its origin to the gold-bearing rocks of the Witwatersrand Basin (Figure 1.1). The basin-roughly oval in shape, approximately 350 km north east to south west direction and stretching over 150 km across-host seven major goldfields. Figure 1.1 The Witwatersrand basin (Viljoen and Reimold, 1999) 1 The gold-bearing conglomerate mined in the Witwatersrand Basin has a typical mineralogical composition of (Feather and Koen, 1975): • Quartz (70-90%); • Phyllosilicates (10-30%), consisting mainly of sericite, KAl 2(AlSi 3O10 )(OH) 2; • Accessory and minor minerals (1-5%). Some 70 different ore minerals have been identified in the conglomerates, the most abundant of which, after pyrite, are uranite (UO 2), brannerite (UTi 2O6), arsenopyrite (FeAsS), cobaltite (CoAsS), galena (PbS), pyrrhotite (FeS), gerdofite (NiAsS) and chromite (FeCr 2O4). Amalgamation Amalgamation was the principal gold recovery method used in South African gold mines at the start of mining in 1886. Crude amalgamation is still practiced by some artisanal gold miners in South Africa, mainly in the Mpumalanga Province. Unfortunately the method is in widespread use in some African countries (Sudan, Tanzania, D.R.

  • The Use of Sodium Cyanide in Wildlife Damage Management
    Human Health and Ecological Risk Assessment for the Use of Wildlife Damage Management Methods by USDA-APHIS-Wildlife Services Chapter VII THE USE OF SODIUM CYANIDE IN WILDLIFE DAMAGE MANAGEMENT May 2017 Peer Reviewed Final October 2019 THE USE OF SODIUM CYANIDE IN WILDLIFE DAMAGE MANAGEMENT EXECUTIVE SUMMARY USDA-APHIS Wildlife Services (WS) uses sodium cyanide (NaCN) to manage coyotes, red foxes, gray foxes, arctic foxes, and wild dogs that prey upon livestock, poultry, and federally designated threatened and endangered species or animals that are vectors of disease. This human health and ecological risk assessment is an evaluation of the risks to human health, nontarget animals, and the environment from NaCN use by WS. WS uses the M-44, the name for the ejector device that delivers a single dose NaCN from a capsule, to target canids. The M-44 is spring-activated and is actuated when an animal pulls up on the capsule holder; a plunger propelled by the spring breaks through a capsule with dry NaCN to deliver the contents into the mouth of an animal. The WS applicator baits the M-44 capsule holder sides to attract target canids. Sodium cyanide reacts rapidly with moisture in the mouth or mucus membranes of the nose and eyes to form hydrogen cyanide (HCN), a toxicant. One NaCN capsule contains enough cyanide to be lethal to animals through oral contact, inhalation contact, and moist dermal pathway contact. WS annually averaged the known take of 13,959 target canids and 362 nontarget species with NaCN between FY11 and FY15, recording 1,548,000 Method Nights with M-44s in 17 States.
