Abstract
As part of a programme investigating the fate of transuranium nuclides discharged to coastal waters we have studied the effects of benthic animals on plutonium redistribution in Irish Sea sediments. From analyses of burrow linings of the large echiuroid Maxmulleria lankesteri, which penetrates to depths exceeding 40 cm, we now show that this animal may have a significant effect on the removal of plutonium to deeper layers in the sea bed.
摘要
作为一项调查排放到沿海水域的超铀核素归宿的计划的一部分，我们研究了底栖动物对爱尔兰海沉积物中钚再分布的影响。通过对大型螠虫类动物兰氏大螠（Maxmulleria lankesteri）洞穴衬里的分析，这种螠虫能钻入超过40厘米深的海底，我们现在表明这种动物可能对将钚转移到海床更深层有显著影响。
