| 摘 要： | 于2003-09-06现场采集样品,调查分析了胶州湾沉积物中基质结合态磷化氢的含量和分布.检测结果显示:磷化氢最高浓度达143.75ng/kg(干重).磷化氢在湾内沉积物中含量普遍高于湾外,受人类活动影响污染较为严重的养殖区、河口区等海域沉积物中磷化氢的含量明显高于湾中心和湾外等海域.分析磷化氢与其沉积环境的关系发现,沉积物中磷化氢的含量和分布受到沉积物中有机磷和氧化还原电位、沉积物组成等因素的影响.

| Abstract: | The distribution of matrix-bound phosphine in sediments was investigated in some selective sea areas of Jiaozhou Bay on Sep.6, 2003. Results show that the peak concentration of phosphine reachs to 143.75 ng/kg (dry weight). Moreover, an obvious regularity of distribution is observed that phosphine concentration in coastal sediments is higher than that in offshore's, and concentration within the Bay is higher than that of outside Bay. Results also reveal that phosphine concentration in such seriously polluted areas as culture farm and estuary is significantly higher than that in other investigated places. On the other hand, the relationship between phosphine and its sedimentary environment suggest that the phosphine concentration and distribution are mainly affected by the organic phosphorous, the redox potential and the sediment composition. |
