摘要

摘要: ²¹⁰Bi-²¹⁰Pb核素对被认为是一种新型的可以示踪海洋颗粒物动力学过程的良好示踪剂。由于²¹⁰Bi半衰期较短以及分析难度较大等限制因素的存在，人们对海洋中²¹⁰Bi的生物地球化学行为如何以及是否存在²¹⁰Bi-²¹⁰Pb活度不平衡现象这两个问题缺乏足够认知。本文于2017年5月5日至15日搭载基金委春季航次对长江口外东海赤潮爆发期间水体中溶解态和颗粒态（溶解态+颗粒态=总态）²¹⁰Po、²¹⁰Bi和²¹⁰Pb活度浓度及核素活度比进行了现场观测。结果显示，总态²¹⁰Po/²¹⁰Pb活度比在0.20到2.08之间变化，平均值为0.82±0.58（n=15）；总态²¹⁰Bi/²¹⁰Pb活度比在0.32到3.72之间变化，平均值为1.38±0.79（n=15），表明水体中普遍存在²¹⁰Po-²¹⁰Pb和²¹⁰Bi-²¹⁰Pb活度不平衡现象；而深层水体中存在明显的²¹⁰Po和²¹⁰Bi相对于²¹⁰Pb过剩的现象，表明²¹⁰Po和²¹⁰Bi伴随颗粒物在深层水体中发生再溶出现象。通过计算三种核素的分配系数和分馏因子，本文发现颗粒物在同时清除²¹⁰Po、²¹⁰Bi和²¹⁰Pb的过程中，倾向于优惠清除²¹⁰Po和²¹⁰Bi；与²¹⁰Po类似，²¹⁰Bi表现出比²¹⁰Pb更强的海洋颗粒物亲和活性特征，浮游植物爆发（生物量的增加）能促进²¹⁰Bi与²¹⁰Pb之间的分馏行为，支持了²¹⁰Bi-²¹⁰Pb可用于示踪海洋颗粒物过程的观点。

Abstract: The ²¹⁰Bi-²¹⁰Pb radionuclide pair is considered to be a new radiotracer for particulate carbon dynamics. Due to the very short half-life of ²¹⁰Bi and the difficulty of determination, we have very few knowledge about the biogeochemical behavior of ²¹⁰Bi in the ocean and whether there is a ²¹⁰Bi-²¹⁰Pb activity disequilibrium. This paper reported the observation results of dissolved and particulate ²¹⁰Po, ²¹⁰Bi, and ²¹⁰Pb and their activity ratios in seawaters in the East China Sea close to the Changjiang Estuary during a red tide event on the spring scientific cruise from May 5 to 15, 2017. The results showed that the ²¹⁰Po/²¹⁰Pb activity ratio varied from 0.20 to 2.08, with an average of 0.82±0.58 (n=15) and the ²¹⁰Bi/²¹⁰Pb activity ratio changed between 0.31 and 3.72, showing an average of 1.38±0.79 (n=15). This phenomenon indicates that the activity disequilibrium of ²¹⁰Po-²¹⁰Pb and ²¹⁰Bi-²¹⁰Pb was ubiquitous in the seawater. More specifically, there is an obvious ²¹⁰Po and ²¹⁰Bi excess relative to ²¹⁰Pb in deep seawater, which implied that ²¹⁰Po and ²¹⁰Bi might be released from sinking particles in the middle and deep layer of water column. By calculating the distribution coefficients and fractionation factors of ²¹⁰Po, ²¹⁰Bi, and ²¹⁰Pb, it was found that suspended particles in seawater tended to preferentially scavenge and remove ²¹⁰Po and ²¹⁰Bi, comparing with ²¹⁰Pb. Similar to ²¹⁰Po, ²¹⁰Bi showed a stronger particle affinity for marine suspended particles than ²¹⁰Pb, and the increase of phytoplankton biomass can promote the fractionation behavior between ²¹⁰Bi and ²¹⁰Pb, supporting the idea that ²¹⁰Bi-²¹⁰Pb can be used to trace particle processes in the ocean.
