  • P-Listed Hazardous Wastes
    P-Listed Hazardous Wastes The Environmental Protection Agency (EPA) has identified a number of chemicals on the EPA “P-list” that present an especially acute hazard when disposed of as hazardous waste. Because of their acute hazards, there are more stringent requirements when disposing of these wastes: ►Container size: When collecting p-listed chemicals as waste, the volume of the hazardous waste container must not exceed one quart (approximately one liter). ►Empty containers: Empty containers that held p-listed chemicals must also be disposed of as hazardous waste. They are not allowed to be washed or re-used. ►Contaminated materials: Disposable materials that become contaminated with p-listed chemicals (e.g. gloves, weighing boats, etc.) must also be disposed of as hazardous waste. Non-disposable materials must be “triple-rinsed”, or rinsed three times to remove the contamination. This rinsate must be collected as hazardous waste. Materials contaminated with p-listed chemicals may not be washed or re-used until they have been triple-rinsed. Remember: - Label the waste as hazardous waste. Most common p-listed wastes Just like all other hazardous wastes, p-listed Chemical CAS number wastes must be labeled with the words Acrolein 107–02–8 “hazardous waste”, the complete chemical Allyl alcohol 107–18–6 name, and the associated hazard Arsenic compounds Varies characteristics (e.g., ignitable, corrosive, Inorganic cyanide Varies toxic, or reactive). salts Carbon disulfide 75-15-0 - Use disposable materials whenever Cyanogen and 460-19-5, 506-77-4 possible. Triple-rising non-disposable Cyanogen Chloride material generates a lot of waste, which can 2,4-Dinitrophenol 51–28–5 be difficult to dispose of safely.

  • Effect of Vitamin D on Chronic Behavioral and Dental Toxicities of Sodium Fluoride in Rats
    Fluoride Vol. 36 No. 3 189-197 2003 Research Report 189 EFFECT OF VITAMIN D ON CHRONIC BEHAVIORAL AND DENTAL TOXICITIES OF SODIUM FLUORIDE IN RATS Perumal Ekambaram,a Vanaja Paulb Chennai (Madras), India SUMMARY: Adult female Wistar rats were treated daily for 60 days with so- dium fluoride (500 ppm NaF = 226 ppm fluoride ion) in drinking water, alone or in combination with vitamin D (200 IU/kg by oral intubation). Throughout the period, food intake was measured daily. Body weight gain, exploratory motor activity (EMA) rota-rod motor coordination, dental structure, brain acetylcho- linesterase (AchE) activity, and serum fluoride and serum calcium concentra- tion were determined 24 hr after the last treatment. Serum fluoride concentra- tion increased markedly in the NaF-treated animals and was accompanied by decreased food intake, reduced body weight gain, impairment of EMA and motor coordination, dental lesions, inhibition of brain AchE activity, and hy- pocalcemia. Administration of vitamin D along with NaF prevented hypocal- cemia. However, the toxic action fluoride on motor coordination, brain AchE activity, and the teeth was not prevented in these animals, probably because vitamin D is not able to decrease the level of fluoride in the serum. Therefore, vitamin D has only limited value as a protective dietary factor against chronic toxic effects of fluoride. Keywords: Dental lesions; Fluoride toxicity; Locomotor behavior; Rat toxicity; Serum calcium; Serum fluoride; Vitamin D. INTRODUCTION Fluorides are naturally occurring contaminants in the environment.1 Pro- longed ingestion of drinking water containing 1–3 ppm of fluoride ion pro- duces deleterious effects on skeletal, dental,1 and soft tissues,2,3 enzyme ac- tivities,4 and locomotor behavior5 in animals.

  • Proceedings of the Indiana Academy Of
    Preliminary Tests with Systemic Insecticides 1 George E. Gould, Purdue University A systemic insecticide is one that is absorbed by the plant and translocated in the sap so that parts of the plant other than those treated become toxic to sucking insects. This type of insecticidal action was demonstrated for selenium compounds by Gnadinger (1) and others as early as 1933. These compounds were never used extensively as quantities of the material dangerous to humans accumulated in sprayed plants or in plants grown in treated soils. Recently German chemists have developed a number of phosphorus compounds that show systemic action. In our tests three of these compounds have been tried in com- parison with three related phosphorus compounds for which no systemic action has been claimed. The development of these systemic and other phosphorus compounds have been based on the discoveries of the German chemist Schrader in 1942 (German patent 720,577). After World War II this information became available to the Allied Governments and soon numerous com- pounds were released for experimental purposes. At present three of the non-systemic compounds, parathion, hexaethyl tetraphosphate and tetraethyl pyrophosphate, are available commercially. The first of the systemics tested was C-1014, a formulation similar to Pestox 3 (octa- methylpyrophosphoramide) which has been used in England. The other two in our tests were Systox with its active ingredient belonging to a trialkyl thiophosphate group and Potasan, diethoxy thiophosphoric acid ester of 7-hydroxy-4-methyl coumarin. Two additional phosphorus com- pounds used in some tests included Metacide, a mixture containing 6.2% parathion and 24.5% of 0, O-dimethyl O-p-nitrophenyl thiophos- phate, and EPN 300, ethyl p-nitrophenyl thionobenzine phosphonate.

  • ADA Fluoridation Facts 2018
    Fluoridation Facts Dedication This 2018 edition of Fluoridation Facts is dedicated to Dr. Ernest Newbrun, respected researcher, esteemed educator, inspiring mentor and tireless advocate for community water fluoridation. About Fluoridation Facts Fluoridation Facts contains answers to frequently asked questions regarding community water fluoridation. A number of these questions are responses to myths and misconceptions advanced by a small faction opposed to water fluoridation. The answers to the questions that appear in Fluoridation Facts are based on generally accepted, peer-reviewed, scientific evidence. They are offered to assist policy makers and the general public in making informed decisions. The answers are supported by over 400 credible scientific articles, as referenced within the document. It is hoped that decision makers will make sound choices based on this body of generally accepted, peer-reviewed science. Acknowledgments This publication was developed by the National Fluoridation Advisory Committee (NFAC) of the American Dental Association (ADA) Council on Advocacy for Access and Prevention (CAAP). NFAC members participating in the development of the publication included Valerie Peckosh, DMD, chair; Robert Crawford, DDS; Jay Kumar, DDS, MPH; Steven Levy, DDS, MPH; E. Angeles Martinez Mier, DDS, MSD, PhD; Howard Pollick, BDS, MPH; Brittany Seymour, DDS, MPH and Leon Stanislav, DDS.

The question is whether these admissions are indeed necessary. Objective The aim of this study was to develop a model that predicts the need of ICU treatment (receiving mechanical ventilation and/or vasopressors <24 h of the ICU admission and/or in- hospital mortality). Materials and methods We performed a retrospective cohort study from a national ICU-registry, including 86 Dutch ICUs. We aimed to include only observational admissions and therefore excluded admissions with treatment, at the start of the admission that can only be applied on the ICU (mechanical Current Awareness in Clinical Toxicology is produced monthly for the American Academy of Clinical Toxicology by the Birmingham Unit of the UK National Poisons Information Service, with contributions from the Cardiff, Edinburgh, and Newcastle Units.
