我们监测了21种微量元素的浓度在西北地中海沿岸生态系统（意大利）的浮游动物样品。在过去的20年里，这一地区一直是重要的人为影响的目标，包括海上交通和大量的工业活动。浮游动物有助于将微量金属转移到更高的营养级，是海洋环境中金属基线研究的建议类别之一。必需微量元素（As，Cu，Mn，Zn，Fe，Mo，Co，Cr，Se，Ni）和非必需微量元素（Al，Be，Cd，Pb，Sb，Sn，V）在浮游动物样品中的浓度一般不受关注，但在不同季节和不同水深之间表现出重要的变化。浮游动物被认为是一个重要的积累金属，生物积累系数的范围为28（钴）至10，9015（铁）在海洋表层沃茨，随着水深的增加值。浮游动物是评估海洋环境中金属污染及其影响的有用生物指示物。(C)2016爱思唯尔有限公司版权所有
We monitored the concentration of 21 trace elements in zooplankton samples collected in a Northwestern Mediterranean coastal ecosystem (Italy). In the last 20 years, this area has been the target of important anthropogenic impacts including maritime traffic and substantial industrial activities. Zooplankton contributes to the transfer of trace metals to higher trophic levels and constitute one of the recommended groups for the baseline studies of metals in the marine environment. The essential trace elements (As, Cu, Mn, Zn, Fe, Mo, Co, Cr, Se, Ni) and the nonessential trace elements (Al, Be, Cd, Pb, Sb, Sn, V) were generally found at concentrations of no concern in the analyzed zooplankton samples, but showed important variations between seasons and different water depths. The zooplankton was found to be a significant accumulator of metals, and bioaccumulation factors were in the range of 28 (Co) to 10,9015 (Fe) in marine surficial waters, with increasing values at increasing water depth. Zooplankton is a useful bioindicator to assess metal contamination and its impact in the marine environment. (C) 2016 Elsevier Ltd. All rights reserved.
