Abstract

ABSTRACT Concentrations of trace elements in Late Pleistocene lake sediments from two localities in West Flanders (Belgium) were studied using inductively coupled plasma-mass spectrometry. The studied sediments were deposited during the transition of the Allerød to the Younger Dryas. Trace elements enter lake environments from a variety of sources, but mostly from bedrock weathering in catchments and as wind-blown dust particles. These sources create a natural trace element background in lake sediment records. The concentration and distribution of trace elements across the studied lake sediment sequences display features consistent with inputs of materials other than those from soil or bedrock. Input from volcanic eruptions, biomass burning and meteorite impacts should be considered among the main sources of non-anthropogenic contamination of lake environments.

比利时西佛兰德斯晚更新世湖泊沉积物古污染地球化学记录

采用电感耦合等离子体质谱法研究了比利时西佛兰德斯两个地区晚更新世湖泊沉积物中微量元素的浓度。所研究的沉积物沉积于阿勒谷期到新仙女木期的过渡时期。微量元素从各种来源进入湖泊环境，但主要来自集水区的基岩风化和风吹的尘埃颗粒。这些来源在湖泊沉积物记录中创造了自然的微量元素背景。研究的湖泊沉积物层序中微量元素的浓度和分布与土壤和基岩以外的物质输入特征一致。火山喷发、生物质燃烧和陨石撞击等是非人为污染湖泊环境的主要来源。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
