Abstract. Iodine compounds destroy ozone (O3) in the global troposphere and form new aerosols, thereby affecting radiative balance. However, few reports have described latitudinal distribution of atmospheric iodine compounds. This work monoxide (IO) measurements taken over unprecedented sampling areas from Arctic to Southern Hemisphere spanning sea surface temperatures (SSTs) approximately 0 31...

A detailed set of reactions treating the gas and aqueous phase chemistry of the most important iodine species in the marine boundary layer (MBL) has been added to a box model which describes Br and Cl chemistry in the MBL. While Br and Cl originate from seasalt, the I compounds are largely derived photochemically from several biogenic alkyl iodides, in particular CH2I2, CH2ClI, C2H5I, C3H7I, or...

The most commonly-used test for determining the serum concentration of thyroid hormones is the protein-bound iodine analysis (PBI) which measures the serum's entire organic and some inorganic iodide concentration. Since it is desired to measure only that portion of the serum iodine which is in the thyroxine molecule, this test may be misleading. The method of PBI determination rou tinely used i...

When I(131)-albumin is given intravenously to rabbits, the radioactive breakdown products that are released into the plasma and urine can be extracted into acetone. Paper chromatography and paper electrophoresis show that about 80 per cent of these are I(131)-iodide and the remainder are organic I(131)-iodine compounds. When I(131)-iodide is given to rabbits taking iodide in their drinking wate...

The method cannot be used to measure the amount of each 13II-labelled compound quantitatively because of the losses of organic radioiodine (see Table 1) at each step. Quantitative analyses of the organic radioiodine fraction is probably best performed by removal of iodide on a column of silver chloride followed by butanol extraction and paper chromatography of the remaining organic iodine compo...

The (ab initio) effective potential method developed previously has been applied to several molecules in order to establish a basis set and effective potential for iodine and to examine aspects of the potential surfaces of hypervalent compounds of iodine. Implied lone-pair stereochemical activity is found to agree well with experiment. Results for the structures and force constants closely rese...

The possibilities of application of iodine as a titrant in determination of sulfur compounds have been presented. The influence of the reaction medium, the nature of compounds, and the thiol–thione tautomerism on the reaction stoichiometry of sulfur compounds with iodine has been discussed. The conditions of volumetric titration with visual and potentiometric end-point detection and coulometric...

BACKGROUND AND OBJECTIVES Iodine nutritional status in pregnant women is important for neuronal development of the fetus, and may vary depending on the geographic area. Thyroid function and urinary iodine excretion were therefore assessed in pregnant women from three different provinces of a large Spanish autonomous community. PATIENTS AND METHODS A descriptive study was conducted in the thre...
