It serves as the source of names chosen for use in all agency documents and internal communications. Chemicals are listed, alphabetically by preferred name, in the body of the glossary. The preferred name is printed in bold-face type, as is the CAS Registry number assigned by Chemical Abstracts Service (not available for some entries). Alternate names are identified by type of name. An index provides a cross-reference to the preferred name for each alternate name. Use the index to find the name used for any chemical in the body of the Glossary. Then find the main entry for that chemical to obtain additional alternate names and other information. The glossary includes parent pesticides with U.S. tolerances on foods or feeds (40 CFR 180, 185, 186), or with temporary or pending tolerances. It also includes pesticides which previously had U.S. tolerances, those known or suspected of being used on foods in other countries, and those for which common names have recently been approved by ANSI and/or ISO. Absence of a chemical which meets these criteria is either inadvertent or results from failure to locate sufficient information for entry. The glossary contains only limited entries for pesticide components, metabolites, breakdown products, or impurities; see page iii for directions on how to obtain information about additional chemicals in these categories. The glossary also contains only selected industrial chemicals, usually those known to be detected during analysis of foods for pesticide residues. Preferred names were chosen according to the following sequence: • ANSI (American National Standards Institute) approved common name • ISO (International Standards Organization) approved common name • other common names • acronym or other term which has gained general acceptance • chemical name if sufficiently short • trade name In some cases where no ANSI or ISO name exists, the preferred name was chosen from among several possibilities because it has already been used within the agency for a period of time. Other Information The following additional information is included, if available, for each chemical: Use: most common use of pesticide; left blank for components, metabolites, etc. Category: parent, metabolite, etc. Molecular Formula: Numbers are not subscripted. LMS Code: as used by FDA to report analytical results. Tolerances: references to 40 CFR 180 and 40 CFR 185-86; also notes temporary, pending, or revoked tolerances and indicates use in other countries (“foreign use”). October 2001 page i Naming Conventions Names proposed as ANSI common names, but not yet approved, are not normally used. When exceptions are made, the notation “(prop)” is included with the name. Names proposed as ISO common names and considered acceptable by mail ballot are used, even when they have not yet appeared in a Draft Addendum to ISO document 1750, Pesticides and other agrochemicals—Common names. Names approved as ISO common names but designated as unacceptable in the U.S. are listed in the Glossary but are not used as preferred names, even when no ANSI name exists. Certain “other” names are entered for explanatory purposes, e.g., “captan metabolite”, “chlordane component”. In some cases, these names will occur once for each of the chemicals to which they refer. Chemical names which follow the nomenclature rules of the Chemical Abstracts Service’s 9th Collective Index (9CI) are used for all entries for which such a name exists. In certain cases, other chemical names are also included; these are labelled as “other” names. Chemical names are entered in direct order. Exceptions to this rule include the following stereochemical descriptors, which are printed after the name following a comma: • cis- and trans- • alpha, beta, etc., (sometimes abbreviated to A, B, etc. for space considerations) • o-, m-, and p- •(±)-, (+), and (-) • (E)- and (Z)- • endo- and exo- • (R)- and (S)- • D- and L- Note that alpha, beta, and other descriptors are also used as locants in some names; in these cases, the terms are not abbreviated and are not placed at the end of the name. When other descriptors appear elsewhere than at the beginning of the name, or if placing them at the end of a very long name would cause confusion, they have been left in place. Names are alphabetized by computer according to the following sequence: space ! + # $ % & + ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ] An “=” is used to create an artifical line break in a long chemical name; no space or hyphen occurs in the actual name at that point. Second and subsequent lines of long names are indented in order to avoid confusion when there are two or more names within a category, e.g., more than one 9CI or Other name. page ii October 2001 Acknowledgement This Glossary was developed by Bernadette McMahon, formerly of FDA Division of Pesticides and Industrial Chemicals. Ann Marie Poulsen and John J. Jennings, Jr. of Division of Information Resources Management, Library and Information Resources Branch, provided on-line searches of Chemical Abstracts Service information, as well as invaluable advice about the esoterica of chemical nomenclature. Corrections Report corrections, additions or comments on the FDA Glossary of Pesticide Chemicals to: Carolyn Makovi, FDA Division of Pesticides and Industrial Chemicals, HFS-337, 200 C Street SW, Washington, DC 20204; Email: [email protected]. Database Files As previously noted, only limited entries exist in the Glossary for pesticide components, metabolites, breakdown products, and impurities. More complete listings are available in files FDA makes available in a format suitable for creating databases. For example, this Glossary contains entries for 1022 chemicals (with 5688 alternate names); the 2001 version of the database files contains records for approximately 1900 chemicals. Also available in the database files is other information useful to the laboratory or administrator dealing with pesticides. Particular emphasis is given to data on the behavior of chemicals in FDA multiresidue analytical methods published in Pesticide Analytical Manual Vol. I (PAM I). FDA provides the database files in electronic format on the Internet for access via World Wide Web. Basic information about the files, how to obtain them, and how to use them follows. Explanatory files that accompany the data files provide more details. What the Files Are The following two sets of files are available, each in compressed .exe form. These can be decompressed on Windows systems by double-clicking, and on Macintosh systems by use of Stuffit Expander; access to this decompression software is provided.

  • Appendix H EPA Hazardous Waste Law
    Appendix H EPA Hazardous Waste Law This Appendix is intended to give you background information on hazardous waste laws and how they apply to you. For most U.S. Environmental Protection Agency (EPA) requirements that apply to the University, the Safety Department maintains compliance through internal inspections, record keeping and proper disposal. In Wisconsin, the Department of Natural Resources (DNR) has adopted the EPA regulations, consequently EPA and DNR regulations are nearly identical. EPA defines This Appendix only deals with "hazardous waste" as defined by the EPA. hazardous waste as Legally, EPA defines hazardous waste as certain hazardous chemical waste. This hazardous chemical Appendix does not address other types of regulated laboratory wastes, such as waste; radioactive, infectious, biological, radioactive or sharps. Chapter 8 descibes disposal procedures infectious and biohazardous waste for animals. Chapter 9 describes disposal procedures for sharps and other waste that are regulated by can puncture tissue. Chapter 11 discusses Radiation and the Radiation Safety for other agencies. Radiation Workers provides guidelines for the disposal of radioactive waste. Procedures for medical waste are written by the UW Hospital Safety Officer. The Office of Biological Safety can provide guidance for the disposal of infectious and biological waste. EPA regulations focus on industrial waste streams. As a result, many laboratory chemical wastes are not regulated by EPA as hazardous chemical waste. However, many unregulated chemical wastes do merit special handling and disposal If a waste can be procedures. Thus, Chapter 7 and Appendix A of this Guide recommend disposal defined as: procedures for many unregulated wastes as if they were EPA hazardous waste.

Introduction The successful use of pesticides around the world has been due to their excellent control of pests such as insects, algaes, bacterias, viruses, rodents, or nematodes in agriculture, medicine, household, and industry. Since 9 of the 12 most dangerous and persistent organic pollutants are pesticides, therefore their qualitative and/or quantitative detection continue being one of the most strategic technological areas, given that these can be found in substances in contact with humans and other animals. The effects associated with their consumption and control, are related to human health and environmental toxicity. One of the most important contributions of the environmental chemistry is the control of pesticide residues and metabolites in food, water and soil; where plants, animal and human contacts are possible. Several methods to detect pesticides have been developed, chromatographic methods such as gas chromatography (GC) and high performance liquid chromatography (HPLC), which are coupled with mass spectrometry (MS).

  • Enzymatic Degradation of Organophosphorus Pesticides and Nerve Agents by EC: 3.1.8.2
    catalysts Review Enzymatic Degradation of Organophosphorus Pesticides and Nerve Agents by EC: 3.1.8.2 Marek Matula 1, Tomas Kucera 1 , Ondrej Soukup 1,2 and Jaroslav Pejchal 1,* 1 Department of Toxicology and Military Pharmacy, Faculty of Military Health Sciences, University of Defence, Trebesska 1575, 500 01 Hradec Kralove, Czech Republic; [email protected] (M.M.); [email protected] (T.K.); [email protected] (O.S.) 2 Biomedical Research Center, University Hospital Hradec Kralove, Sokolovska 581, 500 05 Hradec Kralove, Czech Republic * Correspondence: [email protected] Received: 26 October 2020; Accepted: 20 November 2020; Published: 24 November 2020 Abstract: The organophosphorus substances, including pesticides and nerve agents (NAs), represent highly toxic compounds. Standard decontamination procedures place a heavy burden on the environment. Given their continued utilization or existence, considerable efforts are being made to develop environmentally friendly methods of decontamination and medical countermeasures against their intoxication. Enzymes can offer both environmental and medical applications. One of the most promising enzymes cleaving organophosphorus compounds is the enzyme with enzyme commission number (EC): 3.1.8.2, called diisopropyl fluorophosphatase (DFPase) or organophosphorus acid anhydrolase from Loligo Vulgaris or Alteromonas sp. JD6.5, respectively. Structure, mechanisms of action and substrate profiles are described for both enzymes. Wild-type (WT) enzymes have a catalytic activity against organophosphorus compounds, including G-type nerve agents. Their stereochemical preference aims their activity towards less toxic enantiomers of the chiral phosphorus center found in most chemical warfare agents. Site-direct mutagenesis has systematically improved the active site of the enzyme. These efforts have resulted in the improvement of catalytic activity and have led to the identification of variants that are more effective at detoxifying both G-type and V-type nerve agents.

Standard therapy with atropine and established oxime-type enzyme reactivators is unsatisfactory. Experimental data indicate that superior therapeutic results can be obtained when reversible cholinesterase inhibitors are administered before OPC exposure. Comparing the protective efficacy of five such cholinesterase inhibitors (physostigmine, pyridostigmine, ranitidine, tacrine, or K-27), we observed best protection for the experimental oxime K-27.

  • View Is Primarily on Addressing the Issues of Non-Permanently Charged Reactivators and the Development of Treatments for Aged Ache
    Design, Synthesis, and Evaluation of Therapeutics for the Treatment of Organophosphorus Poisoning by Nerve Agents and Pesticides Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Andrew Joseph Franjesevic Graduate Program in Chemistry The Ohio State University 2019 Dissertation Committee Professor Christopher M. Hadad, Advisor Professor Thomas J. Magliery Professor David Nagib Professor Jonathan R. Parquette Copyrighted by Andrew Joseph Franjesevic 2019 2 Abstract Organophosphorus (OP) compounds, both pesticides and nerve agents, are some of the most lethal compounds known to man. Although highly regulated for both military and agricultural use in Western societies, these compounds have been implicated in hundreds of thousands of deaths annually, whether by accidental or intentional exposure through agricultural or terrorist uses. OP compounds inhibit the function of the enzyme acetylcholinesterase (AChE), and AChE is responsible for the hydrolysis of the neurotransmitter acetylcholine (ACh), and it is extremely well evolved for the task. Inhibition of AChE rapidly leads to accumulation of ACh in the synaptic junctions, resulting in a cholinergic crisis which, without intervention, leads to death. Approximately 70-80 years of research in the development, treatment, and understanding of OP compounds has resulted in only a handful of effective (and approved) therapeutics for the treatment of OP exposure. The search for more effective therapeutics is limited by at least three major problems: (1) there are no broad scope reactivators of OP-inhibited AChE; (2) current therapeutics are permanently positively charged and cannot cross the blood-brain barrier efficiently; and (3) current therapeutics are ineffective at treating the aged, or dealkylated, form of AChE that forms following inhibition of of AChE by various OPs.
