2001年12月份在我国胶州湾东北部沉积物中检测出磷化物的一种新的存在形式——基质结合态磷化氢,并对其含量、分布等进行了分析和研究.发现其浓度随沉积物取样深度和站位的不同而变化,通常底层沉积物磷化氢含量高于表层沉积物,PH3最高浓度可达685 ng/kg(干重),远远高于目前文献所报道的在湖泊、稻田、垃圾场等陆源中基质结合态磷化氢的浓度.相关分析表明,该磷化氢浓度与沉积物无机磷浓度没有明显的相关性,与沉积物底层有机磷浓度具有较好的线性相关性,R2达0.83.胶州湾沉积物中的磷化氢主要来源于厌氧环境下的有机磷化合物分解,其含量与有机磷浓度和厌氧环境有关.
In December 2001, a new form of phosphide, matrix-bound phosphine, was detected in the sediments of the northeastern Jiaozhou Bay in our country, and its content and distribution were also analyzed and studied. Sediment sampling depth and station varies, usually the bottom sediment phosphine content higher than the surface sediment, PH3 maximum concentration of up to 685 ng / kg (dry weight), much higher than currently reported in the literature Lakes, paddy fields, landfills, etc. The correlation analysis showed that there was no significant correlation between the concentration of phosphine and the concentration of inorganic phosphorus in the sediments, which was in good agreement with the concentration of organic phosphorus in sediments R2 was 0.83.The phosphine in the sediments of Jiaozhou Bay mainly came from decomposition of organophosphorus compounds in anaerobic environment, and its content was related to the concentration of organic phosphorus and the anaerobic environment.
