一种海洋环境中易被忽略的磷化合物——磷化氢

PHOSPHINE, A PHOSPHORUS COMPOUND WHICH USED TO BE OVERLOOKED IN STUDY OF MARINE ENVIRONMENTAL SCIENCES

根据国内外最新研究进展 ,对以往海洋环境研究中往往忽略的一种磷化物———磷化氢 (Phosphine)的存在形式、分布特征、与其他形态之间的相互转化以及在磷的生物地球化学循环中的作用和地位等进行了综合评述。认为磷化氢是磷在海洋环境中普遍存在的一种形式 ,与磷的其他氧化形态之间存在着相互转化的关系 ,尽管目前对其转化机制、在磷循环中的地位和作用等方面尚不清楚 ,但磷化氢对海洋生物可利用性磷的贡献应是一个不可忽视的因子 ,在磷循环过程中应是重要的一环 ,在将来进一步深入讨论磷的生物地球化学过程。

Based on the updated development in domestic and abroad study on phosphine, we synthetically viewed that the existence, distribution, transformation of phosphine as well as the contribution in biogeochemical cycle of phosphorus in marine environment, which used to be overlooked in the studies. It was considered that phosphine is one of phosphorus compounds ubiquitous in marine environment. There is transformation between phosphine and other phosphorus compounds with different redox states. Although it is not very clear about the transformation mechanism, function etc., the contribution of phosphine to biologically available phosphorus and the effect of phosphine on phosphorus cycle should be taken into account in the future study of phosphorus biogeochemical cycle.
