本研究旨在评估里海南部表层沉积物中砷（As）、铜（Cu）、铬（Cr）、钴（Co）、钒（V）、镍（Ni）、铅（Pb）和锌（Zn）的主要元素和重金属含量。沉积物中金属元素含量的顺序为：V> Cr > Zn > Ni > Co > Cu > Pb > As。元素之间的相关性表明，沉积物的TOM、粒度和化学成分是影响重金属分布的主要因素。根据污染负荷指数（PLI），部分采样点的沉积物受到污染。在一些采样点，镍、砷、铬和铜的浓度高于沉积物质量准则，这意味着这些金属可能产生不利影响。(c)2014爱思唯尔有限公司版权所有。
This study aimed to evaluate major elements and heavy metal concentrations of Arsenic (As), Copper (Cu), Chromium (Cr), Cobalt (Co), Vanadium (V), Nickel (Ni), lead (Pb) and Zinc (Zn) in surface sediments of the southern Caspian Sea. Metal contents in the sediment were observed in the order of: V> Cr > Zn > Ni > Co > Cu > Pb > As. Correlations between elements showed that sediment TOM, grain size and chemical composition are the main factors that influence the distribution of heavy metals. According to the pollution load index (PLI), sediments from some sampling sites were polluted. Concentrations of Ni, As, Cr and Cu were higher than sediment quality guidelines at some sampling sites, implying potential adverse impacts of these metals. (c) 2014 Elsevier Ltd. All rights reserved.
