This work investigated the distribution of matrix-bound phosphine in surface sediments of Jinpu Bay and associated environmental factors in summer, using the gas chromatography combined with a pulsed flame detector (GC-PFPD). It showed that phosphine ubiquitously presented in the sediments of Jinpu Bay. Contents of matrix-bound phosphine varied between 62. 58 and 190. 81 ng.kg-1, with the average value of 114.42 ng.kg-1. In addition, the spatial distribution of matrix-bound phosphine indicated that matrix-bound phosphine in inshore sediments had relatively higher contents than those in offshore sediments. Statistical analysis showed that matrix-bound phosphine significantly related to organic phosphorus and alkaline phosphatase activity ( R = 0. 882, P = 0. 01; R = 0. 819, P =0. 023). However, there were no correlations between matrix-bound phosphine and organic nitrogen, inorganic phosphorus and sediment grain sizes. These results implied that accumulation and distribution of matrix-bound phosphined were mainly affected by the decomposition of organic phosphorus by microorganisms.
本研究在夏季利用气相色谱联用脉冲火焰检测器（GC-PFPD），对金浦湾表层沉积物中与基质结合的磷化氢分布及相关环境因素进行了调查。结果表明，金浦湾沉积物中普遍存在磷化氢。与基质结合的磷化氢含量在62.58至190.81 ng·kg-1之间，平均值为114.42 ng·kg-1。此外，与基质结合的磷化氢的空间分布表明，近岸沉积物中与基质结合的磷化氢含量相对高于离岸沉积物。统计分析表明，与基质结合的磷化氢与有机磷和碱性磷酸酶活性显著相关（R = 0.882，P = 0.01；R = 0.819，P = 0.023）。然而，与基质结合的磷化氢与有机氮、无机磷和沉积物粒度之间没有相关性。这些结果表明，与基质结合的磷化氢的积累和分布主要受微生物对有机磷分解的影响。
