  • The Thimerosal Controversy
    The Thimerosal Controversy Aimee Sutherland, VRG Research Assistant April 2013 Background In the early 1920s, a major public health concern was vaccine contamination with bacteria and other germs, which could result in the death of children receiving the vaccines from tainted vials. In the book “The Hazards of Immunization”, Sir Graham S. Wilson depicts an occurrence of contamination that happened in Australia in 1928 in which twelve out of twenty-one children died after receiving the vaccine for diphtheria due to multiple staphylococcal abscesses and toxemia (FDA). This incident spurred the development of preservatives for multi-dose vials of vaccine. In 1928, Eli Lilly was the first pharmaceutical company to introduce thimerosal, an organomercury compound that is approximately 50% mercury by weight, as a preservative that would thwart microbial growth (FDA). After its introduction as a germocide, thimerosal was often challenged for its efficacy rather than its safety. The American Medical Association (AMA) published an article that questioned the effectiveness of the organomercury compounds over the inorganic mercury ones (Baker, 245). In 1938 manufacturers were required to submit safety-testing information to the Food and Drug Administration (FDA). Although preservatives had already been incorporated into many vaccines, it was not until 1968 that preservatives were required for multi-dose vials in the United States Code of Federal Regulations (FDA). In 1970s the American population, increasingly concerned about environmental contamination with heavy metals, began to have reservations about the safety of organomercury and the controversy regarding thimerosal ensued after. The Controversy In 1990s, the use of thimerosal as a preservative became controversial and was targeted as a possible cause of autism because of its mercury content.

  • Low Molecular Weight Fluorescent Probes (Lmfps) to Detect the Group 12 Metal Triad
    chemosensors Review Low Molecular Weight Fluorescent Probes (LMFPs) to Detect the Group 12 Metal Triad Ashley D. Johnson, Rose M. Curtis and Karl J. Wallace * The Department of Chemistry and Biochemistry, The University of Southern Mississippi, Hattiesburg, MS 39406, USA; [email protected] (A.D.J.); [email protected] (R.M.C.) * Correspondence: [email protected]; Tel.: +1-601-266-4715 Received: 2 March 2019; Accepted: 19 April 2019; Published: 28 April 2019 Abstract: Fluorescence sensing, of d-block elements such as Cu2+, Fe3+, Fe2+, Cd2+, Hg2+, and Zn2+ has significantly increased since the beginning of the 21st century. These particular metal ions play essential roles in biological, industrial, and environmental applications, therefore, there has been a drive to measure, detect, and remediate these metal ions. We have chosen to highlight the low molecular weight fluorescent probes (LMFPs) that undergo an optical response upon coordination with the group 12 triad (Zn2+, Cd2+, and Hg2+), as these metals have similar chemical characteristics but behave differently in the environment. Keywords: chemosensors; fluorescence; recognition; sensing; group 12 metals (zinc; cadmium; and mercury) 1. Introduction Sensors are used in every aspect of modern life; for example, many modern households have a carbon monoxide sensor or a smoke detector installed. In industry, fiber-optic sensors are used for monitoring process variables, such as temperature, pressure flow, and the level of a liquid. The environment requires sensors to monitor toxic gases and air pollution, and in clinical applications for the detection of medical conditions, i.e., Type 1 diabetes. The field of sensor technology has rapidly been expanding over the last several decades, and the field can be categorized into two broad areas (1) chemical sensors and (2) biosensors.

Individual ionic OTC, OLC and OMC compounds were identified and their concentrations determined in the gas phase, aerosol particles, and bulk precipitation at a rural (Waldstein) and an urban (Bayreuth city) site in NE-Bavaria. At both sites, butyltins, methyltins, octyltins, trimethyllead and monomethylmercury concentrations in the gas phase were o100 pg mÀ3 (determined as corresponding Sn, Pb and Hg concentrations, respectively) with the dominance of tri- and di-substituted OTC and octyltins. The same species were found in bulk precipitation with concentrations o25 ng lÀ1 (Sn, Pb, Hg) with the dominance of mono-substituted OTC. In aerosols, only butyltins, dimethyltin and monomethyltin (o500 pg Sn mÀ3) were found and mono-substituted OTC predominated. No significant difference of concentrations of organometallic compounds in the atmosphere at the two sites was found. For OTC, the washout factors was in the order: mono-Xdi-4tri-substituted OTC, and the gas/ particle partition coefficients were mono-bdi-btri-substituted OTC.

ReceiuedAugust 24, 1973 Abstract: Reaction of alkylmercuric halides with sodium borohydride in dimethylformamide saturated with molecular oxygen producesalcohols and borate estersin good yields. The products obtained following reaction of neophylmercuric bromide (l), 1,7,7-trimethylbicyclol2.2.llheptyl-2-mercuricbromide (9), and endo- and exo-nor- bornyl-2-mercuric bromides (13 and l4) with borohydride in the presenceof oxygen are compatible with a reaction mechanism involving free, noncaged,alkyl radicals as intermediates. This mechanism finds further support in the observationsthat rcaction of I with borohydride and oxygen in solutions containing2,2,6,6-tetramethylpiperidoxyl radical leads to good yields of thc prodr-rctof coupling of neophyl radical with the nitroxyl.

One of the recom- mendations made by this meeting was that the international organizations of the United Nations family should assist in the collection and distribution of information on environmental mercury. Subsequently, the organizations concerned agreed that a handbook on mercury contamination would be es- pecially useful. This would deal with sources of mercury in relation to man and his environment; with physical and biological transfer processes that determine its distribution; with analytical methods for determining mercury and its compounds as environmental contaminants; with actual concentrations of mercury found in the environment, in living organisms and in man; and with its toxicology in animals and man.

  • Appendix 2 Case Study: Thimerosal and Mercury Toxicity in Humans
    Appendix 2 Case Study: Thimerosal and Mercury Toxicity in Humans The Preservative Thimerosal Thimerosal is a preservative that was invented in 1920 by the chemist, Eli Lilly, the founder of the pharmaceutical company of the same name (Kirby 2005 p48). It is an organomercurial compound that is almost 50% mercury by weight and metabolises to ethylmercury and thiosalicylate. Its brand name is Merthiolate and it is a cream- coloured water soluble crystalline powder (Kirby 2005). This preservative has never been tested for safety and effectiveness since it was first used in the 1930’s (FDA p1). The first requirement for preservatives to be included in the US Code of Federal Regulations (CFR) was in 1968 but preservatives were present in many products prior to this time. The CFR requires that ‘the preservative shall be sufficiently non-toxic so that the amount present in the recommended dose of the product will not be toxic to the recipient…’ (FDA p1). Yet the FDA does not test preservatives for safety and efficacy. FDA safety and effectiveness standards only apply to collecting safety and effectiveness data on the product that is being licensed not on the preservative that is in the product for licensing. Whilst the FDA states that the concentration of thimerosal in vaccines meets the preservative standards set by the United States Pharmacopeia these standards do not refer to the safety of the preservative – only to its effectiveness. In other words, it kills the specified challenge organisms and is able to prevent the growth of the fungi when it is at a concentration in the range of 0.001% - 0.01%.

An Abstract of The Study of Lanthanides for Organometallic and Separations Chemistry by Andrew Charles Behrle Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in Chemistry The University of Toledo December 2012 Part 1. The effective use of f-element complexes as catalysts for reactions such as hydroamination and hydrophosphination has been demonstrated in many recent reports. Unfortunately, the homoleptic starting materials underpinning this chemistry are generally derived from only a handful of ligands. That is, of the homoleptic lanthanide complexes that exist, the majority make use of alkylsilane (-CH2SiMe3), silylamide (- N(SiMe3)2), or benzyl (-CH2C6H5) derivatives. The paucity of tri-alkyl lanthanide complexes can be attributed to the required extended coordination sphere and high Lewis acidity or electrophilicity of these metals. While these properties make lanthanum alkyl complexes very reactive, in turn they also make their synthesis and manipulation quite challenging.

  • Synthesis and Reactivity of Group 12 Β-Diketiminate Coordination Complexes
    Synthesis and Reactivity of Group 12 β-Diketiminate Coordination Complexes By Dylan Webb A thesis Submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Masters of Science In Chemistry Victoria University of Wellington 2016 Abstract The variable β-diketiminate ligand poses as a suitable chemical environment to explore unknown reactivity and functionality of metal centres. Variants on the β-diketiminate ligand can provide appropriate steric and electronic stabilization to synthesize a range of β-diketiminate group 12 metal complexes. This project aimed to explore various β-diketiminate ligands as appropriate ancillary ligands to derivatise group 12 element complexes and investigate their reactivity. i A β-diketiminato-mercury(II) chloride, [o-C6H4{C(CH3)=N-2,6- Pr2C6H3}{NH(2,6- i i Pr2C6H3)}]HgCl, was synthesized by addition of [o-C6H4{C(CH3)=N-2,6- Pr2C6H3}{NH(2,6- i Pr2C6H3)}]Li to mercury dichloride. Attempts to derivatise the β-diketiminato-mercury(II) chloride using salt metathesis reactions were unsuccessful with only β-diketiminate ligand degradation products being observed in the 1H NMR. i A β-diketiminato-cadmium chloride, [CH{(CH3)CN-2,6- Pr2C6H3}2]CdCl, was derivatized to a i β-diketiminato-cadmium phosphanide, [CH{(CH3)CN-2,6- Pr2C6H3}2]Cd P(C6H11)2, via a lithium dicyclohexyl phosphanide and a novel β-diketiminato-cadmium hydride, [CH{(CH3)CN-2,6- i Pr2C6H3}2]CdH, via Super Hydride. Initial reactivity studies of the novel cadmium hydride with various carbodiimides yielded a β-diketiminato-homonuclear cadmium-cadmium i dimer, [CH{(CH3)CN-2,6- Pr2C6H3}2Cd]2, which formed via catalytic reduction of the cadmium hydride.
