“…For iodide, iodate, MIT, and DIT, the respective LODs were 2.64, 0.76, 0.78, and 0.50 ng/g and the corresponding LOQs were 6.29, 3.21, 1.10, and 0.72 ng/g. In comparison with previous studies employing an anion exchange column, the LOD and LOQ obtained herein were far lower (Romarís‐Hortas et al., ; Romarís‐Hortas et al., ; Zhang et al., ). The accuracy of the method was verified by employing a CRM.…”

“…To separate iodine using anion exchange HPLC‐ICP‐MS, certain mobile phases were screened in a prior study (Han et al., ; Romarís‐Hortas et al., ; Romarís‐Hortas et al., ; Zhang et al., ). Given that ammonium nitrate (NH 4 NO 3 ) dissolved in ultrapure water exhibited the most powerful elution power without overlap of the peaks, it was selected as the mobile phase.…”

The speciation in environmental water system was selected as target in this paper. The contents of total iodine and its speciation in environmental water system including groundwater, tap water, pure water, lake water, rain water, snow water and sea water which used as comparison with surface water had been discussed. As the results revealed, the contents and speciation of iodine in different environmental water system were different from each other. The region of Changchun of China was a section of moderate iodine which judged by tap water, ground water and lake water. However and the existent speciation of iodine in these three waters were IO3for tap water, Ifor ground water with nearly both were 100 % and IO3-, Iand other perhaps organics species for lake water, rain water, snow water and sea water.

“…In the past, iodine concentration or speciation has been measured in natural and drinking water (Chen et al, 2007;Liu et al, 2015;Wang and Jiang, 2008;Wei et al, 2007), precipitation (Gilfedder et al, 2007a;Yoshida et al, 2007), soil (Yoshida et al, 2007), animal and microalgae tissues (Hughes et al, 2006;Kaňa et al, 2015;Shah et al, 2005), edible salts (Yun et al, 2017;Zhang et al, 2010), and milk (Wang and Jiang, 2008). Previous measurements in ambient aerosols showed only three iodine species: I -, iodate (IO 3 -) and total soluble organic iodine (SOI) and their relative concentration and size distribution varied largely with locations (e.g.…”

<p><strong>Abstract.</strong> Intense new particle formation (NPF) events were observed in the coastal atmosphere during algae growth and farming season at Xiangshan Gulf of east China coast. High nucleation-mode iodine concentrations measured by ultra-performance liquid chromatography coupled with quadruple time-of-flight mass spectrometry (UPLC/Q-TOF-MS) confirmed that the NPF events were induced by iodine species. Farmed microalgae, as well as wild algae, could be an important NPF source in coastal areas of China. For the first time, we identified 5 inorganic iodine species, 45 organic iodine compounds (35 molecular formulas) and a group of iodide-organic adducts in ambient aerosols. The concentrations and size distributions of iodine species down to 10 nanometers were measured during the iodine-induced NPF, continental NPF and non-NPF days at the coastal site and compared to those at an inland site. The iodine in the above four types of aerosol samples were characterized by iodate, aromatic iodine compounds, iodoacetic acid/iodopropenoic acid and iodide-organic adducts, respectively. This study sheds light on the iodine sources, formation mechanism and its contribution to the coastal NPF in the context of heavy air pollution in eastern China.</p>
