Determination of the Residual Efficacy of Carbamate and Organophosphate
Yewhalaw et al. Malar J (2017) 16:471 DOI 10.1186/s12936-017-2122-3 Malaria Journal RESEARCH Open Access Determination of the residual efcacy of carbamate and organophosphate insecticides used for indoor residual spraying for malaria control in Ethiopia Delenasaw Yewhalaw1,2†, Meshesha Balkew3†, Josephat Shililu4, Sultan Suleman5, Alemayehu Getachew4, Gedeon Ashenbo4, Sheleme Chibsa6, Gunawardena Dissanayake6, Kristen George7, Dereje Dengela8, Yemane Ye‑Ebiyo4 and Seth R. Irish9* Abstract Background: Indoor residual spraying is one of the key vector control interventions for malaria control in Ethiopia. As malaria transmission is seasonal in most parts of Ethiopia, a single round of spraying can usually provide efective protection against malaria, provided the insecticide remains efective over the entire malaria transmission season. This experiment was designed to evaluate the residual efcacy of bendiocarb, pirimiphos-methyl, and two doses of pro‑ poxur on four diferent wall surfaces (rough mud, smooth mud, dung, and paint). Filter papers afxed to wall surfaces prior to spraying were analyzed to determine the actual concentration applied. Cone bioassays using a susceptible Anopheles arabiensis strain were done monthly to determine the time for which insecticides were efective in killing mosquitoes. Results: The mean insecticide dosage of bendiocarb applied to walls was 486 mg/m2 (target 400/mg). This treat‑ ment lasted 1 month or less on rough mud, smooth mud, and dung, but 4 months on painted surfaces. Pirimiphos- methyl was applied at 1854 mg/m2 (target 1000 mg/m2), and lasted between 4 and 6 months on all wall surfaces. Propoxur with a target dose of 1000 mg/m2 was applied at 320 mg/m2, and lasted 2 months or less on all surfaces, except painted surfaces (4 months). -

Florida State Emergency Response Commission
Florida State Emergency Response Commission Sub-Committee on Training (SOT) HAZARDOUS MATERIALS MEDICAL TREATMENT PROTOCOLS Version 3.3 TOXIDROMES Toxidromes are clinical syndromes that the patient presents with. These patterns of signs and symptoms are essential for the successful recognition of chemical exposure. The toxidromes identified in this protocol are chemical exposure based while others such as the opioids are found within general medical protocol. These chemical toxidromes are identified clinically into five syndromes: Irritant Gas Toxidrome Asphyxiant Toxidrome Corrosive Toxidrome Hydrocarbon and Halogenated Hydrocarbons Toxidrome Cholinergic Toxidrome Each can present as a clinical manifestation of the chemical/poisoning involved with some cross-over between toxidromes. This list combines the toxic syndromes found within NFPA 473 (A.5.4.1(2) and traditional syndromes.

CC BY 4.0 License. 52 Abstract 53 54 Condensed phase uptake and reaction are important atmospheric removal processes for reduced nitrogen 55 species, isocyanic acid (HNCO), methyl isocyanate (CH3NCO) and cyanogen halides (XCN, X =Cl, Br, I), yet many 56 of the fundamental quantities that govern this chemistry have not been measured or are understudied. Solubilities 57 and first-order reaction rates of these species were measured for a variety of solutions using a bubble flow reactor 58 method with total reactive nitrogen (Nr) detection. The aqueous solubility of HNCO was measured as a function of 59 pH, and exhibited the classic behavior of a weak acid, with an intrinsic Henry’s law solubility of 20 (±2) M/atm, and -4 60 a Ka of 2.0 (±0.28) ×10 M (which corresponds to pKa = 3.7 ±0.06) at 298K. -
Hydroxyacetonitrile (HOCH2CN) As a Precursor for Formylcyanide (CHOCN), Ketenimine (CH2CNH), and Cyanogen (NCCN) in Astrophysical Conditions

Danger1, F. Duvernay1, P. Theulé1, F. Borget1, J.-C. Guillemin2, and T. Chiavassa1 1 Aix-Marseille Univ, CNRS, PIIM UMR 7345, 13397 Marseille, France e-mail: [email protected] 2 Institut des Sciences Chimiques de Rennes, École Nationale Supérieure de Chimie de Rennes, CNRS, UMR 6226, Avenue du Général Leclerc, CS 50837, 35708 Rennes Cedex 7, France Received 8 June 2012 / Accepted 19 November 2012 ABSTRACT Context. The reactivity in astrophysical environments can be investigated in the laboratory through experimental simulations, which provide understanding of the formation of specific molecules detected in the solid phase or in the gas phase of these environments. In this context, the most complex molecules are generally suggested to form at the surface of interstellar grains and to be released into the gas phase through thermal or non-thermal desorption, where they can be detected through rotational spectroscopy. Here, we focus our experiments on the photochemistry of hydroxyacetonitrile (HOCH2CN), whose formation has been shown to compete with aminomethanol (NH2CH2OH), a glycine precursor, through the Strecker synthesis. Aims. We present the first experimental investigation of the ultraviolet (UV) photochemistry of hydroxyacetonitrile (HOCH2CN) as a pure solid or diluted in water ice. Methods. We used Fourier transform infrared (FT-IR) spectroscopy to characterize photoproducts of hydroxyacetonitrile (HOCH2CN) and to determine the different photodegradation pathways of this compound. To improve the photoproduct identifications, irradiations of hydroxyacetonitrile 14N and 15N isotopologues were performed, coupled with theoretical calculations. -

Chlorpyrifos, Part 1: Toxicology
JOURNAL OF PESTICIDE REFORM/ WINTER 1994 • VOL.14, NO. 4 ■ INSECTICIDE FACTSHEET CHLORPYRIFOS, PART 1: TOXICOLOGY The broad spectrum organophosphate insecticide chlorpyrifos is the most widely used insecticide in the U.S. Total use is estimated at almost 30 million pounds per year. Like all organophosphate insecticides, chlorpyrifos affects the nervous system by inhibiting an enzyme that is important in the transmission of nerve impulses. Symptoms of acute poisoning include headache, nausea, muscle twitching, and convulsions. Chlorpyrifos poisonings are reported to state and federal agencies more often than poisonings of almost every other insecticide. In both laboratory animals and humans, chlorpyrifos can also cause delayed effects on the nervous system. Some effects have been measured years after exposure. Human birth defects have been associated with exposure to chlorpyrifos products. In pregnant laboratory animals, chlorpyrifos exposure caused fetal death. Pups that did survive were smaller pups and did not survive as well as pups from unexposed mothers. Chlorpyrifos also affects the male reproductive system; exposure to a chlorpyrifos product has caused death of cells in male rat testes and a decrease in sperm production in cattle. Chlorpyrifos has caused genetic damage in human blood and lymph cells, mice spleen cells, and hamster bone marrow cells. Immune system abnormalities have been reported from patients exposed to chlorpyrifos. Many individuals report developing sensitivities to a broad array of substances following chlorpyrifos exposure. The second part of this factsheet will discuss human exposure to chlorpyrifos and the ecological effects of chlorpyrifos.
