Page 16 INTRODUCTION Scope The objective of the study was to independently validate analytical method as given in the DAS study 171407 [1] for the determination of Florpyrauxifen benzyl (XDE-848 BE), X11438848 and X11966341 in compost in accordance to the guidance documents SANCO/825/00, rev. 8.1 [2] and SANCO/3029/99 rev. 4 of the European Commission [3], and OCSPP 850.6100 of the United States Environmental Protection Agency [4]. The limit of quantification was 0.00015 mg/kg for Florpyrauxifen benzyl (XDE-848 BE), 0.00045 mg/kg for X11438848 and 0.009 mg/kg for X11966341 Analytical Procedure Compost samples were extracted by shaking with acetonitrile/0.1N hydrochloric acid (90:10, v/v), centrifuging, and decanting into a separate tube containing QuEChERS Citrat kit. An aliquot of 1N HCl was added to the extract followed by centrifugation. After a portion of the organic layer was aliquoted, internal standard was added and the sample was evaporated to near dryness under a stream of nitrogen. 1N HCl was added and the samples were incubated for one hour at 80 °C. Ethyl acetate was added and the samples were transferred to a Supel QuE Z-Sep tube and centrifuged. After centrifuging, the samples were placed in a dry ice bath to flash freeze the aqueous layer and the organic layer was poured off into a glass tube. The samples were evaporated under a stream of nitrogen, reconstituted in methanol and 0.1% formic acid in water, and transferred into an autosampler vial for analysis. The samples were analyzed for XDE-848 BE and its metabolites by liquid chromatography with positive ion electrospray ionization tandem mass spectrometry Selectivity Quantification was performed by use of LC-MS/MS detection.

Solution Density Modelling for Single and Mixed Base Metal Electrolytes at Ionic Level
CORE Metadata, citation and similar papers at core.ac.uk Provided by Wits Institutional Repository on DSPACE SOLUTION DENSITY MODELLING FOR SINGLE AND MIXED BASE METAL ELECTROLYTES AT IONIC LEVEL Trevor Chagonda A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Metallurgical Engineering Johannesburg 2013 DECLARATION I declare that this research report is my own unaided work. It is being submitted in partial fulfilment of the requirements of the degree of Master of Science in Metallurgical Engineering at the University of Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination to any other university. ……………………………………. (Signature of Candidate) …………….. DAY OF ……………………………. YEAR …………………… ABSTRACT Solution density modeling is important in hydrometallurgical processes as accurate predictions of single and mixed electrolytes can be used in the design of equipment and their sizing, heat transfer calculations and choosing of materials for construction. This research project entails modeling of electrolyte solutions by extending the Laliberte and Cooper (compound level) model to ionic level where an electrolyte solution is modeled as a mixture of cations, anions and water molecules. This modeling predicts single and mixed electrolyte density as a function of electrolyte temperature in degrees Celsius; water, cation and anion apparent volumes in cubic centimeters; and their respective concentrations in the electrolyte as mass fractions. The model was developed by fitting single electrolyte density data reported in literature using the least squares method in Microsoft Excel®. The following 26 single electrolyte solutions were used in the fitting exercise: Al2(SO4)3, BaCl2, CaCl2, CdSO4, CoCl2, CuSO4, FeCl3, FeSO4, HCl, HCN, HNO3, K2CO3, LiCl, MgSO4, MnCl2, Na2SO3, NaF, NaI, NaOH, (NH4)2SO4, NiCl2, SrCl2, ZnCl2, ZnBr2, (NH4)2C2O4 and KNO2.

Human Health Criteria Options February 2017
Water Quality Policy 1-11 Updates Human Health Criteria February 2017 Outline of Issues covered: I. Background II. Factors to consider for the use of tissue samples Tissue sample representativeness Species to represent segment/site fidelity III. Factors to consider for the use of water samples IV. Lines of Evidence Tissue exposure concentration Drinking water exposure concentration Water column data DOH fish advisories Safe Drinking Water Act (SDWA) MCL values V. Weight of evidence VI. Category determinations I. Background The surface water quality standards include a section on toxic substances (WAC 173-201A-240) for the protection of designated uses. Numeric criteria have been developed for the designated uses of aquatic life and the protection of human health. Uses associated with human health are fish and shellfish harvesting (consumption of fish) and domestic water supply (drinking water). Human health-based water quality criteria used by the state prior to December 2016 were contained in the National Toxics Rule. Currently approved human health criteria (HHC) for Washington are a combination of state-adopted criteria and EPA promulgated criteria. In previous Water Quality Assessments, toxics data from fish tissue was used to assess for the protection of human health, deriving a Fish Tissue Equivalent Concentration (FTEC) as a means to back-calculate fish tissue pollutant concentrations to approximate surface water pollutant concentrations. This was done by applying bioconcentration factors (BCF) that were used to derive the HHC in the National Toxics Rule. The intent of the FTEC used for the past several years was to represent a water column criteria equivalent. On December 14, 2016, Ecology held a public dialogue session on human health criteria.

Ledgemont Laboratory, Kennecott Copper Corporation, Lexington, Massachusetts Received May 3, 1965 ABSTRACT A new calculation of the relation between the electrophoretic mobility and the/-- potential of a spherical colloid particle is presented. The model consists of a rigid, electrically insulating sphere surrounded by a Gouy-Chapman double layer. The ap- propriate differential equations (which account for both electrophoretic retardation and relaxation effect) have been solved without approximations on an IBM 704 com- puter. The theoretical assumptions and the basic equations ~re stated. A detailed account of the solutions of the equations is pub]ished elsewhere. The present paper contains the complete results. Comparison of these results with those of Overbeek ~nd of Booth shows that, %r high ~--potential ~nd 0.2 < ~a < 50, their approximations gen- erally overestimate the relaxation effect. The application to practical cases (espe- cially colloid particles in solutions of 1-1 electrolytes) is discussed extensively.

Calculating Water Quality-Based Effluent Limitations for Surface Water Discharges
BUREAU OF WATER QUALITY PROGRAM GUIDANCE Wastewater Policy and Management Team Wisconsin Department of Natural Resources 101 S. Webster Street, P.O. Box 7921 Madison, WI 53707-7921 Calculating Water Quality-Based Effluent Limitations for Surface Water Discharges 08/10/2020 EGAD Number: 3400-2020-13 This document is intended solely as guidance and does not contain any mandatory requirements except where requirements found in statute or administrative rule are referenced. Any regulatory decisions made by the Department of Natural Resources in any matter addressed by this guidance will be made by applying the governing statutes and administrative rules to the relevant facts. _____________________________________________________________________________________ APPROVED: Adrian Stocks 12/07/2020 _______________________________ __________ Adrian Stocks, Director Date Bureau of Water Quality Summary Section 283.13(5), Wis. Stats., requires that effluent limitations be established in permits for point source discharges to surface water to ensure that applicable state water quality standards are met. These types of effluent limitations are protective of water quality and are referred to as water quality- based effluent limits (WQBEL). The WQBEL calculation process completed by the Wisconsin Department of Natural Resources (the department) involves a site-specific evaluation of the discharge receiving water and effluent characteristics and comparison to state water quality standards. This guidance is intended for use by department staff who are responsible for calculating WQBELs. The document covers how WQBELs are calculated, how staff determine if limits are needed in permits, and how those limits should be expressed in WPDES permits for point source discharges to Wisconsin surface waters. The following guidance documents also provide information on WQBEL calculation procedures and are used by WQBEL calculation staff.

Corrosion and Deuterium Uptake of Zr-Based Alloys in Supercritical Water
CW-124680-CONF-001 UNRESTRICTED - ILLIMITÉ Corrosion and Deuterium Uptake of Zr-based Alloys In Supercritical Water D. Khatamian AECL, Chalk River Laboratories, Stn. 55 Chalk River, ON K0J 1J0, Canada [email protected] Abstract To increase the thermodynamic efficiency above 40% in nuclear power plants, the use of supercritical water as the heat transport fluid has been suggested. Zircaloy-2, -4, Zr-Cr-Fe, Zr-1Nb and Zr-2.5Nb were tested as prospective fuel cladding materials in 30 MPa D2O at 500 C. Zircaloy-2 showed the highest rates of corrosion and hydriding. Although Zr-Cr-Fe initially showed a very low corrosion rate, it displayed breakaway corrosion kinetics after 50 h exposure. The best-behaved material both from a corrosion and hydrogen uptake point of view was Zr-2.5Nb. However, the Zr-2.5Nb oxide growth rate was still excessive and beyond the current CANDU design allowance. Similar coupons, coated with Cr, were also tested. The coated layer effectively prevented oxidation of the coupons except on the edges, where the coating was thinner and had some flaws. In addition, the Cr-coated Zr-2.5Nb coupons had the lowest deuterium pickup of all the alloys tested and showed no signs of accelerated or non- uniform corrosion. CANDU–CANada Deuterium Uranium is a registered trademark of Atomic Energy of Canada Ltd. 2 CW-124680-CONF-001 UNRESTRICTED - ILLIMITÉ 1.0 INTRODUCTION In a nuclear power plant, increasing thermodynamic efficiency and simplifying plant design are the two major ways of reducing unit energy cost. To increase the thermodynamic efficiency above 40%, the use of high-pressure supercritical water at 500 C and above, as the heat transport fluid (HTF), has been suggested [1,2].
