The material has NOT been classified as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence. EYE ! Although the material is not thought to be an irritant, direct contact with the eye may cause transient discomfort characterized by tearing or conjunctival redness (as with windburn). Slight abrasive damage may also result. SKIN ! The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting. ! 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 is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting. ! 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 ! 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. Exposure to the material may cause concerns for humans owing to possible developmental toxic effects, on the basis that similar materials tested in appropriate animal studies provide some suspicion of developmental toxicity in the absence of signs of marked maternal toxicity, or at around the same dose levels as other toxic effects but which are not a secondary non-specific consequence of other toxic effects. 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. Systemic rubidium produces altered behaviour and manic-depressive states, and impairs the uptake of iodine by the thyroid. The effect on renal function of solution of rubidium chloride infused close-arterially to the kidney has been studied in experiments on sheep. The material altered urine flow and electrolyte excretion by acting upon common mechanisms which were predominantly intra-renal and located in the proximal segment of the nephron. [Journal of Physiology, Vol.245, No1, 1975] Rats and mice that are not genetically or otherwise predisposed toward audiogenic seizures are rendered susceptible to auditory stimuli by chronic treatment with large doses of rubidium chloride. [Journal of Pharmacology and Experimental Therapeutics, Vol.194, No3, 1975]. 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.

  • The Densities and Cubical Coefficients of Expansion of the Halogen Salts of Sodium, Potas- Sium, Rubidium and Cesium
    BXPANSION OF THE HALOGEN SALTS OF SODIUM, WC. 259 3. No satisfactory explanation of the influence of the KI on the dBu- sion of iodine, is offered, though several possible explanations are con- sidered. UNIVERSITY,VIRGINIA. [CONTRIBUTIONFROM THE ‘I’.JEFFERSON COOLIDGE,JR., CHEMICALLABORATORY OF HARVARDCOLLEGE.] THE DENSITIES AND CUBICAL COEFFICIENTS OF EXPANSION OF THE HALOGEN SALTS OF SODIUM, POTAS- SIUM, RUBIDIUM AND CESIUM. BY GREGORYPAUL BAXTERAND CURTIS CLAYTON WALLACE. Received November 15. 1915. For purposes of computation in the preceding paper upon “Changes in Volume upon Solution in Water of the Halogen Salts of Alkalis” it was necessary to know the densities of the solid salts at different tempera- tures. Since neither these values nor the coefficients of expansion of the salts have been found with accuracy, the problem of determining the densi- ties over the ‘necessary range in temperature, and thus the coeffiuents of expansion, was undertaken. The method employed was that of displacement of toluene. In order to reduce the effect of the errors of experiment, a very considerable quantity of salt was used. Furthermore, especial pains were taken, first in drying the salt, and second, in freeing it as far as possible from entangled air when immersed in toluene in the pycnometer. The pycnometer itself, instead of being of the ordinary stoppered form for solids, was merely a 25 cc. graduated flask, the neck of which was very much constricted at one point to increase accuracy in adjusting the volume of its contents. The diameter of the constriction was about 2.5 mm. which secured an accuracy in setting of about 0.3 mg.

By ~VILLIAMNORMAN RAE. INa paper by Jackson and Derby on ferrous iodide (Amer. Chem. J., 1900, 24, 15), mention is made of the action of bromine vapour on solid ammonium iodide; these authors state that the ammonium iodide first turned black, but as the absorption went on it finally became converted into the scarlet ammonium bronio-iodo-bromide, NH,BrIBr. A curve constructed from the increase in weight of the ammonium iodide and the time of exposure to bromine showed that therel was a marked diminution in the speed of absorption after the first atom of bromine had been added, and they were unable to decide whether th4e black intermediate1 product was another compound, NH,BrI, or only a mixture of ammoniuni bromide and free iodine. The present investigation was under- taken in order to settle this point, and also to determine whether the action of bromine on other solid iodides follows a similar course. Ammonium bromo-iodo-bromide, NH,BrIBr, was prepared by dissolving the calculated quantities of ammonium bromide, iodine, and bromine in a small quantity of water; the solution was a deep ruby-red colour, and when left in a desiccator over phosphoric oxide slowly deposited crystals of the salt. A similar result was obtained starting with ammonium iodide and bromine. A specimen was analysed by adding a weighed quantity to a Published on 01 January 1915.
