Since the detection limit of the longer light path was expected to be lower for homogeneous distributed trace gases, we performed measurements on the short Marine aerosol is highly enriched in iodine, mostly in the form of iodate (IO3–) ions, compared to its relative abundance in seawater. This paper describes a laboratory study of the photochemical reduction of IO3– in the presence of humic acid. Spectroscopic analysis showed that ∼20% of IO3– was converted to "free" iodide (I–) ions and this fraction remained constant as a

Active molecular iodine photochemistry in the Arctic

Snowpack Molecular Iodine Production. Here we report observations of I 2 and snowpack I − in the Arctic. Gas-phase I 2 was observed in the snowpack interstitial air at 10 cm below the sunlit snowpack surface on February 1 and 2, 2014, near Utqiaġvik, AK ().I 2 mole ratios in the snowpack interstitial air peaked at 2.7–5.1 ppt in the early afternoon, just following the solar radiation

There is a continuous circulation of iodine at the surface of the earth. Vegetation absorbs iodine from the atmosphere and the soil, and animals obtain it from vegetation. The crust of the earth yields fresh supplies as it weathers, and rain washes it into the soil and

Speciation of iodine in a soil−water system was investigated to understand the mechanism of iodine mobility in surface environments. Iodine speciation in soil and pore water was determined by K-edge XANES and HPLC−ICP-MS, respectively, for samples collected at a depth of 0−12 cm in the Yoro area, Chiba, Japan. Pore water collected at a 0−6 cm depth contained 50%−60% of organic iodine

Iodine is a key component to health. Since your body can't produce it, you must get it from your diet. Iodine exhibits activity against bacteria, mould, yeasts, protozoa, and many viruses; indeed, of all antiseptic preparations suitable for direct use on humans and

2000/4/1While qualitative description of the distribution of iodine in the oceans exists (see Wong, 1991), there is uncertainty about the various mechanisms which interconvert iodine species; the quantitative modelling of iodine in marine systems is in its infancy (, ).

Microchemical imaging of iodine distribution in the brown

The distribution of iodine clearly shows a huge, decreasing gradient from the meristoderm to the medulla. The contents of iodine reach very high levels in the more external cell layers, up to 191 +/- 5 mg g(-1) of dry weight in stipe sections.

iodine, added in the form of iodate without stabilizers, is relatively meagre, but indicates iodine losses ranging from around 5% to 66% after 12 months. The studies undertaken between 1923 and 1996, are difficult to compare. Variation between rates of iodine

Iodine can be liberated from iodides by other oxi-dizing agents, such as As5+, Sb 5+, Bi, Cu2+, Cr6+, K 3Fe(CN) 6 (potassium ferricyanide), HNO 3, Cl 2, H 2O 2, or ozone. In each of these approaches, the resulting free iodine is titrated and the end point is

Background.The Barrow-in-Furness stable iodine (potassium iodate) tablet pre-distribution scheme was the first of its kind to be introduced to protect the population living around a fixed site nuclear facility in the United Kingdom. Pre-distribution schemes have

Iodine in the ocean is important because small emissions of iodine species to the atmosphere have a significant impact on ozone and air quality. Iodine is converted between two chemical forms by phytoplankton and bacteria, but only one chemical form (iodide) results in atmospheric emissions.
