Title: Novel tests for rapid detection of insecticide resistance in mosquito vectors. Final report, 15 June 1985-31 January 1989

Abstract

This project is concerned with the formulation of novel diagnostic tests for the detection of organophosphate (OP) resistance in individual mosquitoes. Emphasis was placed on the mechanisms of detoxification by esterases and of insensitive acetycholinesterase. Seven diagnostic tests have resulted from this research to date. Five concern esterases, and two insensitive acetylcholinesterase. An eighth procedure concerns the qualification of proteins in single insects and is used in conjunction with other tests to account for variations in the size of the test insect. Three of the tests developed for esterases (FP/Est, NC/Est and MT/Est) utilize the ability of these enzymes to hydrolyze naphthyl acetate, and two (Dot-Blot/Est and ELISA/Est) involve immunological reactions. The tests for insensitive acetylcholinesterase (NC/AChE and MT/AChE) utilize the differences in inhibitory properties of insecticides on insensitive and normal enzymes.

  • During this project, priority was given to research on the formulation of simple diagnostic tests for the detection of organophosphate (OP) resistance in individual mosquitoes. Emphasis was placed on the mechanisms of insensitive acetycholinesterase and of detoxification of OP's by esterases.
  • Factors affecting the formation of protective alumina scales on niobium-base alloys by selective oxidation have been investigated. Alumina cannot be formed in air at l atm. on binary Nb-A1 alloys at any N(Al). Theoretical knowledge of selective oxidation was applied to Nb-A1 alloys to alter behavior. The effects of Al content, temperature, atmosphere, third element additions, and microstructure on the transition from internal to external oxidation of aluminum was evaluated, and conditions under which protective alumina scales can form on Nb-A1 alloys were defined. Third element additions are required to form protective alumina. The most effective additions are those thatmore » can reduce the solubility and diffusivity of oxygen, enhance diffusion of A1, and limit transient oxidation. Additions of Ti, Cr, V and Si were identified as most promising for providing oxidation resistance in Nb-A1 alloys. The feasibility of forming compact, adherent alumina scales on Nb alloys at a minimum N(A1)=0.32 in air at 1100-1600 C was demonstrated. Alumina scale could not be formed below 1100 C. Preoxidation above 1100 C can be used to preform alumina scales that wil protect at lower temperatures, but is effective only if the alloy is not cooled to room temperature prior to exposure at lower temperatures. Rapid-solidification processing does not appear to offer any significant benefit.« less
  • The following report summarizes the development and validation of an analytical method for the analyses of soman (GD), mustard (HD), VX, and tabun (GA) in wastewater. The need for an analytical method that can detect GD, HD, VX, and GA with the necessary sensitivity (< 20 parts per billion (PPB))and selectivity is essential to Medical Research and Evaluation Facility (MREF) operations. The analytical data were generated using liquid-liquid extraction of the wastewater, with the extract being concentrated and analyzed by gas chromatography (GC) methods. The sample preparation and analyses methods were developed in support of ongoing activities within the MREF.more » We have documented the precision and accuracy of the analytical method through an expected working calibration range (3.0 to 60 ppb). The analytical method was statistically evaluated over a range of concentrations to establish a detection limit and quantitation limit for the method. Whenever the true concentration is 8.5 ppb or above, the probability is at least 99.9 percent that the measured concentration will be ppb or above. Thus, 6 ppb could be used as a lower reliability limit for detecting concentrations in excess of 8.5 ppb. In summary, the proposed sample extraction and analyses methods are suitable for quantitative analyses to determine the presence of GD, HD, VX, and GA in wastewater samples. Our findings indicate that we can detect any of these chemical surety materiel (CSM) in water at or below the established U.S. Army Surgeon General's safety levels in drinking water.« less
  • This report presents a state-of-the-art review of soil-washing technologies and their applicability to Superfund sites in the United States. The review includes Superfund site soil and contamination characteristics, as well as soil cleaning technologies, their principles of operation, and process parameters. The technical feasibility of using soil-washing technologies at Superfund sites in the United States is assessed. Contaminants are classified as volatile, hydrophilic, or hydrophobic organics; PCBs; heavy metals; or radioactive material. Soils are classified as either sand, silt, clay, or waste fill. Three generic types of extractive treatments are identified for cleaning excavated soils: water washing augmented with amore » basic or surfactant agent to remove organics, and water washing with an acidic or chelating agent to remove organics and heavy metals; organics-solvent washing to remove hydrophobic organics and PCBs; and air or steam stripping to remove volatile organics.« less
  • A practical synthesis of fluorine-containing phosphonic acids of the type, (HO)2P(O)(CF2)nP(O)(OH)2 (n = 1,2,3,4,6) has been developed from commercially available precursors. Preliminary electrochemical evaluation of (HO)2P(O)CF2CF2P(O)(OH)2 demonstrated the enhanced oxygen solubility of this acid, and the performance of this acid exceeded H3PO4 in short term fuel cell experiments. Methodology for the preparation of (HO)2P(O)CF2SO3H and F2C=CF(CF2)nP(O)(OH)2 (n = 0,1) has also been developed.
