Considered too toxic for use as a food additive, [FAO/WHO food additives committee, 1966]. Formerly used as maturing agent and dough conditioner. Used at rate of 0.000025% and 0.000002% as prophylactic treatment for endemic goitre. Archaic use in medicine as a topical antiseptic. Oxidising agent in volumetric chemical analysis. SYNONYMS K-IO3, "iodic acid, potassium salt", "potassium iodate", "kalium jodatum" Section 2 - HAZARDS IDENTIFICATION CANADIAN WHMIS SYMBOLS EMERGENCY OVERVIEW RISK Contact with combustible material may cause fire. Harmful if swallowed. Risk of serious damage to eyes. Irritating to respiratory system and skin. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ■ Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. ■ Animal studies suggest iodates cause kidney damage and may cause blood cell damage. Large doses produce vomiting. EYE ■ If applied to the eyes, this material causes severe eye damage. SKIN ■ This material can cause inflammation of the skin oncontact in some persons. ■ The material may accentuate any pre-existing dermatitis condition. ■ Open cuts, abraded or irritated skin should not be exposed to this material. ■ Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ■ The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ■ Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled. CHRONIC HEALTH EFFECTS ■ Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. There is limited evidence that, skin contact with this product is more likely to cause a sensitization reaction in some persons compared to the general population. Based on experience with animal studies, there is a possibility that exposure to the material may result in toxic effects to the development of the fetus, at levels which do not cause significant toxic effects to the mother. Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the lung. Prime symptom is breathlessness; lung shadows show on X-ray. Iodine and iodides, may give rise to local allergic reactions such as hives, rupture of skin blood vessels, pain in joints or diseases of the lymph nodes. Iodine and iodides cause goiter and diminished as well as increased activity of the thyroid gland. A toxic syndrome resulting from chronic iodide overdose and from repeated administration of small amounts of iodine is characterized by excessive saliva production, head cold, sneezing, conjunctivitis, headache, fever, laryngitis, inflammation of the bronchi and mouth cavity, inflamed parotid gland, and various skin rashes. Swelling and inflammation of the throat, irritated and swollen eyes and lung swelling may also occur. Swelling of the glottis, necessitating a tracheotomy has been reported. Use of iodides in frequency can cause fetal death, severe goiter, hypothyroidism and the cretinoid appearance of the newborn.

Where Medical attention is not immediately available or where the patient is more than 15 minutes from a hospital or unless instructed otherwise: For advice, contact a Poisons Information Center or a doctor. Urgent hospital treatment is likely to be needed. If conscious, give water to drink. INDUCE vomiting with fingers down the back of the throat, ONLY IF CONSCIOUS. Lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. NOTE: Wear a protective glove when inducing vomiting by mechanical means. In the mean time, qualified first-aid personnel should treat the patient following observation and employing supportive measures as indicated by the patient's condition. If the services of a medical officer or medical doctor are readily available, the patient should be placed in his/her care and a copy of the MSDS should be provided. Further action will be the responsibility of the medical specialist. If medical attention is not available on the worksite or surroundings send the patient to a hospital together with a copy of the MSDS. EYE ■ If this product comes in contact with the eyes: Immediately hold eyelids apart and flush the eye continuously with running water. Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Continue flushing until advised to stop by the Poisons Information Center or a doctor, or for at least 15 minutes. Transport to hospital or doctor without delay. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. SKIN ■ If skin contact occurs: Immediately remove all contaminated clothing, including footwear Flush skin and hair with running water (and soap if available). Seek medical attention in event of irritation. INHALED ■ If fumes or combustion products are inhaled remove from contaminated area. Lay patient down. Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to hospital, or doctor, without delay. NOTES TO PHYSICIAN ■ Treatment regime for bromates may act as a guide for iodate poisonings. Syrup of ipecac or gastric lavage with tap water or perhaps a 1% solution of sodium thiosulfate Administer a demulcent and an analgesic like meperidine (Demerol). Avoid morphine. If readily available, the prompt use of hemodialysis or peritoneal lavage may serve to remove absorbed but unreacted iodate in significant amounts. Administer oxygen. If methaemoglobinaemia becomes severe a replacement transfusion with whole blood may become necessary. DO NOT attempt to correct methaemoglobinaemia with methylene blue as the dye may enhance the toxicity. Sodium thiosulfate solution (100 to 500 ml of 1%) by intravenous drip has been recommended by some authors. Correct dehydration by infusing intravenously a glucose solution (5% in water). Avoid electrolytes (except as above) unless acid-base imbalance or shock becomes severe. Supportive treatment of acute renal failure. [GOSSELIN et al, Clinical Toxicology of Commercial Products, Fifth Edition]. Toxic myocarditis may follow ingestion of oxidizing agents such as peroxides. -------------------------------------------------------------- BASIC TREATMENT -------------------------------------------------------------- Establish a patent airway with suction where necessary. Watch for signs of respiratory insufficiency and assist ventilation as necessary. Administer oxygen by non-rebreather mask at 10 to 15 l/min. Monitor and treat, where necessary, for pulmonary edema . Monitor and treat, where necessary, for shock. Anticipate seizures . DO NOT use emetics. Where ingestion is suspected rinse mouth and give up to 200 ml water (5 ml/kg recommended) for dilution where patient is able to swallow, has a strong gag reflex and does not drool. DO NOT attempt neutralization as exothermic reaction may occur. Skin burns should be covered with dry, sterile bandages, following decontamination. -------------------------------------------------------------- ADVANCED TREATMENT -------------------------------------------------------------- Consider orotracheal or nasotracheal intubation for airway control in unconscious patient or where respiratory arrest has occurred. Positive-pressure ventilation using a bag-valve mask might be of use. Monitor and treat, where necessary, for arrhythmias. Start an IV D5W TKO. If signs of hypovolemia are present use lactated Ringers solution. Fluid overload might create complications. Drug therapy

  • TITRATIONS with POTASSIUM IODATE Potassium Iodate Is a Fairly
    TITRATIONS WITH POTASSIUM IODATE Potassium iodate is a fairly strong oxidizing agent that may be used in the assay of a number of pharmaceutical substances, for instance : benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride and the like. Under appropriate experimental parameters the iodate reacts quantitatively with both iodides and iodine. It is, however, interesting to observe here that the iodate titrations may be carried out effectively in the presence of saturated organic acids, alcohol and a host of other organic substances. The oxidation-reduction methods with potassium iodate invariably based on the formation of iodine monochloride (ICl) in a medium of strong hydrochloric acid solution. Preparation of 0.05 M Potassium Iodate Potassium iodate is dried to a constant weight at 110°C to make it completely free from moisture and then brought to room temperature in a desiccator. It is pertinent to mention here that KIO3 is a very stable salt and may be obtained in a very pure form. Therefore, it is possible to prepare the standard solutions of KIO3 by dissolving the calculated weight of the salt in water and diluting the same to an approximate volume. Since, the normality of iodate solution varies significantly depending on the nature of the reaction, therefore, in usual practice standard iodate solutions of known molarity are used. The reduction of potassium iodate to iodide is usually not feasible in a direct titrimetric method (unlike the reduction of potassium bromate to bromide) and hence, has no viable application in the official procedures ...........................(a) In this type of reaction, 1 mol of KIO3 is 6 equivalent and a 0.05 M solution would be 0.3 N.

  • Consideration of Mandatory Fortification with Iodine for Australia and New Zealand Food Technology Report
    CONSIDERATION OF MANDATORY FORTIFICATION WITH IODINE FOR AUSTRALIA AND NEW ZEALAND FOOD TECHNOLOGY REPORT December 2007 1 Introduction Food Standards Australia New Zealand is considering mandatory fortification of the food supply in Australia and New Zealand with iodine. Generally, the addition of iodine to foods is technologically feasible. However, in some instances the addition of iodine can lead to quality changes in food products such as appearance, taste, odour, texture and shelf life. These changes will depend on the chemical form of iodine used as a fortificant, the chemistry of the food that is being fortified, the food processes involved in manufacture and possible processing interactions that could occur during distribution and storage. Many foods have been fortified with iodine and the potassium salts of iodine compounds have been used as the preferred form. 2 Forms of Iodine Iodine is normally introduced, or supplemented, as the iodide or iodate of potassium, calcium or sodium. The following table lists different chemical forms of iodine along with their important physical properties.

  • Potassium Iodate
    374 Potassium Iodate COHPONENTS: EVALUATOR: (1) Potassium iodate; KI03; [7758-05-6] H. Miyamoto Niigata University Niigata, Japan (2) Water; H20; [7732-18-5] and Mark Salomon US Army ET & DL Fort Monmouth, NJ, USA June, 1986 CRITICAL EVALUATION: THE BINARY SYSTEM Solubility data for KI03 in pure water have been reported in 30 publications (1-28, 35, 36). A summary of the solubility data over the temperature range 273-373 K is given in Table 1. Note that the data from references (15, 16, 20 and 31) have been compiled in the LiI03 chapter, and the data in reference (3) have been compiled in the NaI03 chapter. With the exception of the high temperature study of Benrath et al. (7) which employed the synthetic method, all other studies are based on the isothermal method. From Table 1 it is seen that a number of authors reported identical solubilities in more than one publication, and the evaluators have therefore treated these results as one independent measurement. Thus, at 298.2 K, the data in (3, 8, 10) have been treated as one independent solubility value as have the data reported in (17, 19, 23), and at 323.2 K in (18, 21, 26). Most authors reported the solid phase over the temperature range of 278-323 K as the anhydrous salt, and although Breusov et al. (11) and Benrath et al. (7) did not report the nature of the solid phases over the temperature range of 273-573 K, it probably is the anhydrous salt in all cases. In fitting the solubility data to the two smoothing equations, a number of data points were rejected as the differences in smoothed (calculated) solubilities differed from the experi­ mental values by more than 20 (where a is the standard error of estimate).

  • Haematoxylin Staining Methods
    Haematoxylin staining methods WOLF D. KUHLMANN , M.D. Division of Radiooncology, Deutsches Krebsforschungszentrum, 69120 Heidelberg, Germany Subsequent to immunohistological procedures, counterstaining of tissue sections is helpful for the study of histological and histopathological details. Generally, counterstains are used to obtain supplementary information to that of the primary stain. An effective counterstain should not intrude the major stain, i.e. the immunostained antigen in the tissue section. The right selection of a counterstain will result in important additional information. In most cases, the overall morphology of the tissue section or the staining of nuclear morphology is desired. For the latter, a variety of haematoxylin formulations exist. With our DAB reactions we obtain nice conterstains by using GILL ’S or MAYER ’S haematoxylins. Haematoxylin is obtained from the logwood Haematoxylon campechianum , a tree indigenous to Central America by several extraction and precipitation methods. Haematoxylin can be also produced synthetically, but the natural product is still the agent in common use. The dye was originally used for industrial purpose. In the first attempts to use haematoxylin as a direct dye for histological specimens only poor results were obtained. The potential for haematoxylin in microscopy has been first realized by F BÖHMER (1865) who combined a metallic mordant with haematoxylin to stain tissue sections adequately. Since then, haematoxylin dye solutions contain haematoxylin and an alum (hemalum, alum haematoxylin). Coupling of haematoxylin with a mordant is still the major form in which this dye is used. Many formulations have been devised in the meantime. They vary in the amount of haematoxylin, the type and quantity of aluminium salts, solvents, oxidizing agents and stabilizers.
