Abstract Even though seaweeds have been recognized as key players in the ocean-to-atmosphere transfer of iodine in other parts of the world, there is a complete lack of knowledge about iodine accumulation in seaweeds of the Arabian Gulf. Similarly, very little is known about fluorine in seaweeds, anywhere in the world. Given that the Arabian Gulf is of particular interest due to being an extreme environment, featuring some of the highest temperatures and salinities observed in any marine water body worldwide, this study endeavoured to conduct a preliminary survey of iodine and fluorine levels in 11 of the most common seaweed species in the region, supported by morphological and molecular (DNA barcode)-based identification. Iodine was determined by inductively-coupled plasma-mass spectrometry, while ion chromatography was employed for analysis of fluoride. Species surveyed included Iyengaria stellata, Padina boergesenii, Chondria sp. Dictyota dichotoma, Colpomenia sinuosa, Feldmannia indica, Codium papillatum, Sargassum ilicifolium, S. ilicifolium var. acaraeocarpum, Sargassum asperifolium and Sargassum aquifolium. The findings of S. ilicifolium and S. ilicifolium var. acaraeocarpum reported here are new records both for Kuwait and the Arabian Gulf. P. boergesenii and D. dichotoma are new records for Kuwait.

通过形态学和 DNA 条形码识别的阿拉伯湾海藻中的碘和氟浓度

摘要 尽管海藻已被认为是世界其他地区海洋到大气碘转移的关键参与者，但对阿拉伯湾海藻中碘的积累完全缺乏了解。同样，世界上任何地方对海藻中的氟知之甚少。鉴于阿拉伯湾是一个极端环境，具有在世界范围内任何海洋水体中观察到的最高温度和盐度，因此特别令人感兴趣，本研究努力对 11 个最重要的地区的碘和氟含量进行初步调查。该地区常见的海藻物种，由基于形态和分子（DNA 条形码）的识别支持。通过电感耦合等离子体质谱法测定碘，而离子色谱用于分析氟化物。调查的物种包括 Iyengaria stellata、Padina boergesenii、Chondria sp。Dictyota dichotoma、Colpomenia sinuosa、Feldmannia indica、Codium papillatum、Sargassum ilicifolium、S. ilicifolium v​​ar. acaraeocarpum, Sargassum asperifolium 和 Sargassum aquifolium。S. ilicifolium 和 S. ilicifolium v​​ar. 的发现。这里报告的 acaraeocarpum 是科威特和阿拉伯湾的新记录。P. boergesenii 和 D. dichotoma 是科威特的新记录。这里报告的 acaraeocarpum 是科威特和阿拉伯湾的新记录。P. boergesenii 和 D. dichotoma 是科威特的新记录。这里报告的 acaraeocarpum 是科威特和阿拉伯湾的新记录。P. boergesenii 和 D. dichotoma 是科威特的新记录。
