  • The Persistence and Secondary Poisoning Risks of Sodium Monofluoroacetate (1080), Brodifacoum, and Cholecalciferol in Possums
    THE PERSISTENCE AND SECONDARY POISONING RISKS OF SODIUM MONOFLUOROACETATE (1080), BRODIFACOUM, AND CHOLECALCIFEROL IN POSSUMS C. T. EASON, G. R. WRIGHT, and L. MEIKLE, Manaaki Whenua - Landcare Research, P.O. Box 69, Lincoln, New Zealand. P. ELDER, Steroid and Immunobiochemistry Unit, Christchurch Health Laboratories, Christchurch Hospital, P.O. Box 151, Christchurch, New Zealand. ABSTRACT: To determine the risk of secondary poisoning for animals preying on sub-lethally poisoned brushtail possums, captive possums were treated with near-lethal doses of sodium monofluoroacetate (1080) or brodifacoum, and toxicant concentrations in blood and tissue were monitored over time. Sodium monofluoroacetate was rapidly eliminated from the blood (within three days). Brodifacoum was retained in the liver and, to a lesser extent, the muscle of possums for eight months after dosing. To determine the potential risk for animals scavenging on the carcasses of possums poisoned with cholecalciferol, cats were fed poisoned carcasses for six days. No changes in behavior, appetite, or body weight were observed. Serum calcium concentrations increased slightly, but remained within the normal range for cats.

  • First Evidence of Anticoagulant Rodenticides in Fish in German
    Environmental Science and Pollution Research https://doi.org/10.1007/s11356-018-1385-8 ADVANCEMENTS IN CHEMICAL METHODS FOR ENVIRONMENTAL RESEARCH First evidence of anticoagulant rodenticides in fish and suspended particulate matter: spatial and temporal distribution in German freshwater aquatic systems Matthias Kotthoff1 & Heinz Rüdel2 & Heinrich Jürling1 & Kevin Severin1 & Stephan Hennecke1 & Anton Friesen3 & Jan Koschorreck3 Received: 27 September 2017 /Accepted: 24 January 2018 # The Author(s) 2018. This article is an open access publication Abstract Anticoagulant rodenticides (ARs) have been used for decades for rodent control worldwide. Research on the exposure of the environment and accumulation of these active substances in biota has been focused on terrestrial food webs, but few data are available on the impact of ARs on aquatic systems and water organisms. To fill this gap, we analyzed liver samples of bream (Abramis brama) and co-located suspended particulate matter (SPM) from the German Environmental Specimen Bank (ESB). An appropriate method was developed for the determination of eight different ARs, including first- and second-generation ARs, in fish liver and SPM. Applying this method to bream liver samples from 17 and 18 sampling locations of the years 2011 and 2015, respectively, five ARs were found at levels above limits of quantifications (LOQs, 0.2 to 2 μgkg−1). For 2015, brodifacoum was detected in 88% of the samples with a maximum concentration of 12.5 μgkg−1. Moreover, difenacoum, bromadiolone, difethialone, and flocoumafen were detected in some samples above LOQ. In contrast, no first generation AR was detected in the ESB samples. In SPM, only bromadiolone could be detected in 56% of the samples at levels up to 9.24 μgkg−1.A temporal trend analysis of bream liver from two sampling locations over a period of up to 23 years revealed a significant trend for brodifacoum at one of the sampling locations.

Chapter 4 Pharmacokinetics of Anticoagulant Rodenticides in Target and Non-target Organisms Katherine E. Horak, Penny M. Fisher, and Brian Hopkins 1 Introduction The concentration of a compound at the site of action is a determinant of its toxicity. This principle is affected by a variety of factors including the chemical properties of the compound (pKa, lipophilicity, molecular size), receptor binding affinity, route of exposure, and physiological properties of the organism. Many compounds have to undergo chemical changes, biotransformation, into more toxic or less toxic forms. Because of all of these variables, predicting toxic effects and performing risk assess- ments of compounds based solely on dose are less accurate than those that include data on absorption, distribution, metabolism (biotransformation), and excretion of the compound.

THE EVALUATION OF ALTERNATIVE TOXINS TO SODIUM MONOFLUOROACETATE (1080) FOR POSSUM CONTROL CHARLES T. EASON, Forest Research Institute, P.O. Box 31-011, Christchurch, New Zealand ABSTRACT: Possum control in New Zealand is dependent on the use of sodium monofluroacetate (1080) and cyanide. Although 1080 is highly effective, its use is restricted to government staff. Cyanide is available for a wider group of licensed operators, but cyanide "shyness" reduces its effectiveness. An acute toxicity programme has been set up to identify non- anticoagulant toxins that could be used safely by farmers. Dose-ranging studies showed that possums are susceptible to cholecalciferol, calciferol, gliftor, alpha-chloralose, and nicotine, but not to bromethalin.

  • Question of the Day Archives: Monday, December 5, 2016 Question: Calcium Oxalate Is a Widespread Toxin Found in Many Species of Plants
    Question Of the Day Archives: Monday, December 5, 2016 Question: Calcium oxalate is a widespread toxin found in many species of plants. What is the needle shaped crystal containing calcium oxalate called and what is the compilation of these structures known as? Answer: The needle shaped plant-based crystals containing calcium oxalate are known as raphides. A compilation of raphides forms the structure known as an idioblast. (Lim CS et al. Atlas of select poisonous plants and mushrooms. 2016 Disease-a-Month 62(3):37-66) Friday, December 2, 2016 Question: Which oral chelating agent has been reported to cause transient increases in plasma ALT activity in some patients as well as rare instances of mucocutaneous skin reactions? Answer: Orally administered dimercaptosuccinic acid (DMSA) has been reported to cause transient increases in ALT activity as well as rare instances of mucocutaneous skin reactions. (Bradberry S et al. Use of oral dimercaptosuccinic acid (succimer) in adult patients with inorganic lead poisoning. 2009 Q J Med 102:721-732) Thursday, December 1, 2016 Question: What is Clioquinol and why was it withdrawn from the market during the 1970s? Answer: According to the cited reference, “Between the 1950s and 1970s Clioquinol was used to treat and prevent intestinal parasitic disease [intestinal amebiasis].” “In the early 1970s Clioquinol was withdrawn from the market as an oral agent due to an association with sub-acute myelo-optic neuropathy (SMON) in Japanese patients. SMON is a syndrome that involves sensory and motor disturbances in the lower limbs as well as visual changes that are due to symmetrical demyelination of the lateral and posterior funiculi of the spinal cord, optic nerve, and peripheral nerves.

  • Justification for the Renewal of the Approvals for the Anticoagulant
    Justification for the renewal of the approvals for the anticoagulant rodenticides brodifacoum, bromadiolone, chlorophacinone, coumatetralyl, difenacoum, difethialone, flocoumafen and warfarin Rodent control is essential, and in many cases a legal requirement, to prevent disease transmission, consumption and contamination of food and feedingstuffs, structural damage and to remove social abhorrence. Currently, the anticoagulant rodenticides (also referred to as AVKs) are the dominant and most effective substances for rodent control. Therefore, the current AVK active substances approved for PT 14 will continue to be essential for efficient and effective rodent control in order to maintain good public hygiene and protect public health. The original evaluations for first approval at EU level recognised the need of the AVKs. The corresponding Assessment Reports for the AVKs acknowledged this when they concluded that: According to the Annex I inclusion criteria referred to in Article 10 of the Directive and TNsG on Annex I inclusion, AVKs should not be included in Annex I. However, in the decision making also benefits of using the active substance in the biocidal products have to be considered (Paragraph 96 in Annex VI of the Directive). It is concluded that AVKs are needed as rodenticides for human hygiene and public health reasons. In this exceptional case the benefit should take precedence over the risks and AVKs should be included in Annex I. [The text above is a generalised extract based on the conclusions of the Assessment Reports of the AVKs] All of the AVKs meet one of the exclusion criteria under Article 5(1) of the Biocidal Products Regulation (BPR), which prohibits their approval unless one or more of the derogations provided for in Article 5(2) are met.
