  1. a = inductively coupled plasma mass spectrometry (ICP-MS) with prior ion chromatography
  2. b = value obtained from Sandel-Kolthoff
  3. c = value obtained from ICP-MS with prior alkaline extraction using tetramethylammonium hydroxide
  4. Figures refer to weights in mg/kg dry matter. Measures of iodine content with Sandel-Kolthoff are means ± SEM and (in brackets) the number of repeated runs. All other figures represent means of duplicate and triplicate measurements of the same pooled sample
