“…For I in the soil [156]. It is expected that the water soluble and exchangeable 129 I can easily be taken up by plants through root, while bound in other fractions, such as organic, oxides and minerals is more difficult to be taken up.…”

“…Several methods of ion chromatography (IC), liquid chromatography (LC), size-exclusion chromatography (SEC) and capillary electrophoresis (CE) coupled with different detection methods for iodine and bromine speciation have appeared, including UV detection, 2,6,7 inductively coupled plasma optical emission spectrometry (ICP-OES), 8,9 and inductively coupled plasma mass spectrometry (ICP-MS). 2,[9][10][11][12][13][14][15][16] However, all four species, namely Br − , BrO3 − , I − and IO3 − , have not been reported using a single procedure.…”

An inductively coupled plasma mass spectrometer (ICP-MS) was used as an ion chromatographic detector for the speciation of iodine and bromine. Gradient elution using NH4NO3 at pH 10 allowed the chromatographic separation of ionic iodine (I − and IO3 − ) and bromine (Br − and BrO3 − ) species in less than 8 min. Effluents from the ion-exchange column were delivered to the nebulization system of ICP-MS for the determination of I and Br. The potentially interfering 38 Ar 40 ArH + and 40 Ar 40 ArH + at the bromine masses m/z 79 and 81 were significantly reduced in intensity (by approximately two orders of magnitude) by using 0.6 mL min −1 O2 as a reactive cell gas in the dynamic reaction cell (DRC). Moreover, the signal-to-background ratio at iodine mass m/z 127 increased significantly when O2 was used as the reaction gas. The detection limits were in the range of 0.001 -0.002 and 0.03 -0.04 ng mL −1 for various I and Br compounds, respectively, based on the peak height. The relative standard deviation of the peak areas for five injections of a 2 ng mL −1 I − , IO3 − and 20 ng mL −1 Br − , BrO3 − mixture was in the range of 3 -4%. The concentrations of I and Br compounds have been determined in selected water and urine samples. The spike recoveries were in the range of 94 -102% for all of the determinations. This method has also been applied to determine various I and Br compounds in an NIST RM 8435 whole-milk powder reference material and a seaweed sample obtained locally. A microwave-assisted extraction method was used to extract these compounds, which were quantitatively leached with a 10% mass/volume (m/v) tetramethylammonium hydroxide (TMAH) solution in a focused microwave field within a period of 6 min. The major components of I and Br in milk powder and seaweed were I − and Br − .

“…In addition, the organic I species in human metabolic waste is transformed to I − by the time it leaves the body via urine (Michalke and Schramel, 1999). If no crops provided I (grain fraction = 1), then plant productivity would drop 10% within seven years at a corresponding nutrient solution concentration of 3.4 µM I − .…”

Nutrient recycling in a space-based Bioregenerative Life Support System (BLSS) will require an understanding of nutrient dosage effects on crop production, plant tissue partitioning, and geochemical fates within crop systems. Sodium (Na + ), fluoride (F − ), and iodide (I − ) are found in human waste streams. These elements were examined using crops in hydroponic systems. Lettuce, radish, spinach, and beet were used to study Na
