摘要

沿海沉积物中的重金属会对人类健康和环境产生不利影响。采用标准、测量和测试计划(简称BCR)提出的前两步顺序萃取法,测定了从泰国普吉岛普吉岛湾采集的21份沉积物样品中Pb和Zn的分布和金属生物利用度。结果表明,Pb在第一馏分(BCR1)中形成弱络合物,占其总浓度(1.7 ~ 7.5 mg kg-1)的11.2% ~ 33%,而Zn在BCR1馏分中的含量为4.9% ~ 9.9%。结果表明,Pb容易进入食物链,其污染的主要原因与当地的人为活动和城市化影响有关,如渡轮码头、船坞和其他海上活动。同时,金属的富集因子表现为轻度到中度重度富集。沿沉积物剖面的金属浓度-深度关系表明,沉积物岩心各层金属浓度在45.4 ~ 88 mg Zn kg-1和12.7 ~ 44.5 mg Pb kg-1之间。根据沉积物岩心中重金属积累的变化,以及计算出的富集因子随深度的变化,我们可以了解普吉湾过去活动相关污染物的历史变化。

Spatial Distribution of Bioavailable Metal Concentrations and Total Metal Concentration-depth Relationship along the Sediment Profile within Phuket Bay
Heavy metals in coastal sediments can adversely affect human health and the environment. The distribution and metal bioavailability of Pb and Zn in 21 sediment samples collected from Phuket Bay, Phuket, Thailand using the first-two steps of sequential extraction proposed by the Standards, Measurements and Testing programme (known as BCR) was determined. The results showed that Pb formed weak complexes contributing up to 11.2% to 33% of its total concentration (1.7 to 7.5 mg kg-1) in the first fraction (BCR1), while Zn in the BCR1 fraction ranged from 4.9% to 9.9%. The results suggest that Pb could easily enter the food chain and the main cause of heavy metal contamination is related to local anthropogenic activities and effects of urbanization in the region, such as the ferry terminal, boatyards, and other maritime activities. Meanwhile, the enrichment factors of the metals showed minor to moderately severe enrichment. The metal concentration-depth relationship along the sediment profile showed metal concentration in each layer of the sediment core ranging from 45.4 to 88 mg Zn kg-1 and from 12.7 to 44.5 mg Pb kg-1. Based on the changes in heavy metal accumulation in the sediment core, and the calculated the enrichment factor versus depth, these allowed us to understand the historical variability in pollutant linked to past activities in Phuket Bay.
