根据国内外文献总结了海洋生态系统中主要碘形态分布及其相互转化的研究进展。溶解无机态碘的两种主要形式(碘酸根IO3-及碘离子I-)之间随着海水物理化学性质的改变而发生的形态转换是海洋生态学家相对最为关注的热点问题。研究者们对其反应机理开展了各自的研究,认为其中IO3-的还原机理包括:浮游植物生长调控、细菌活动、硫化物及光化学反应;I-的氧化包括光化学途径及细菌活动等。本文还就海洋生态系统中有关碘的深入研究提出了展望。
According to the literature at home and abroad, the research progress of the distribution and transformation of the main iodine in marine ecosystem is summarized. The morphological transition between the two major forms of dissolved inorganic iodine (iodate IO3- and iodide I-) with the change of the physicochemical properties of seawater is a relatively hot issue of the greatest concern to marine ecologists. Researchers have carried out their own research on the reaction mechanism, which IO3-reduction mechanism that includes: phytoplankton growth and regulation, bacterial activity, sulfide and photochemical reactions; I-oxidation, including photochemical pathways and bacterial activity. The paper also put forward a prospect on the further research on iodine in marine ecosystem.
