Concentrations of total and organic mercury, cadmium, lead, copper, iron, manganese and zinc were determined in the muscular tissue of 135 specimens of Aristeus antennatus (Risso, 1816) collected during a 3-year period in the Ligurian sea (NW Mediterranean). The aim of the present work was to study the relationships between the concentrations of these trace elements and the main biological parameters characterising the organisms, i.e. sex and size with special attention to the sexual maturity of the female specimens. Mercury is the only element showing a significant correlation with the size of the specimens, and for this reason it could give some indications about the age of the shrimps. However, comparison between females collected at four different reproductive phases shows that reproductive individuals are characterised by higher levels of mercury with respect to non-reproductive individuals of the same size.
在三年时间里于利古里亚海(地中海西北部)采集了135份触角真虾(阿里斯提乌斯触角虾,里索,1816年)样本,测定了其肌肉组织中总汞、有机汞、镉、铅、铜、铁、锰和锌的含量。本研究的目的是探讨这些微量元素的含量与表征生物体的主要生物学参数之间的关系,即性别和大小,特别关注雌性样本的性成熟情况。汞是唯一与样本大小呈现显著相关性的元素,因此它可以为虾的年龄提供一些线索。然而,对处于四个不同生殖阶段的雌性样本进行比较发现,与相同大小的未生殖个体相比,处于生殖期的个体汞含量更高。
