摘要

本研究旨在评估法罗湖中五步蛇(Mytilus galloprovincialis)和笛鲷(Tapes decussatus)血淋巴和体液中砷(As)、铜(Cu)、锌(Zn)、镉(Cd)、铅(Pb)和汞(Hg)的潜在生物累积性。由于城市和农业污染源的输入以及较低的水交换率,该湖特别容易积累对水生生物具有潜在毒性的物质。来自第勒尼安海、墨西拿海峡的咸水和来自丘陵含水层的淡水共同在湖中形成了咸水条件,导致该地区的商业贝类产量很高。使用单四极电感耦合等离子体质谱仪测定了砷、镉、铜、铅和锌;使用直接汞分析仪 (DMA-80) 测定了汞。此外,还测定了法鲁湖水的理化参数。使用 GraphPad Prism 9.0(GraphPad 软件公司,美国马萨诸塞州波士顿)进行了统计分析,并采用了 Shapiro-Wilk 正态性分析方法。在作为 "生物指标 "的贻贝和 Tapes decussatus 中,镉、汞和铅的浓度低于允许的最高残留限量,这表明法罗湖没有受到这些污染物污染的风险,而且,根据法规限制,消费者的健康不会受到影响。

Heavy Metals Bioaccumulation in Mytilus galloprovincialis and Tapes decussatus from Faro Lake (Messina), Italy.

The aim of this study was to evaluate the potential bioaccumulation of arsenic (As), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb) and mercury (Hg) in the haemolymph and corpus of Mytilus galloprovincialis and Tapes decussatus from Lake Faro. The lake is particularly prone to the accumulation of substances that are potentially toxic to aquatic organisms, due to the input of pollutants from urban and agricultural sources and the low rate of water exchange. The combination of saltwater from the Tyrrhenian Sea, the Strait of Messina and freshwater from hilly aquifers has created brackish conditions in the lake, resulting in an area of high commercial shellfish productivity. As, Cd, Cu, Pb and Zn were determined using a single quadrupole inductively coupled plasma mass spectrometer; Hg was determined using a direct mercury analyser (DMA-80). Physicochemical parameters of the water from Lake Faro were also performed. Statistical analysis was carried out using GraphPad Prism 9.0 (GraphPad Software, Inc., Boston, MA, USA) and Shapiro-Wilk normality was applied. Concentrations of Cd, Hg and Pb below the permitted MRLs in Mytilus galloprovincialis and Tapes decussatus used as ''biological indicators'' show that Lake Faro is not at risk of contamination by these pollutants and, moreover, is free of health problems for the consumer based on regulatory limits.

期刊介绍: Biological Trace Element Research provides a much-needed central forum for the emergent, interdisciplinary field of research on the biological, environmental, and biomedical roles of trace elements. Rather than confine itself to biochemistry, the journal emphasizes the integrative aspects of trace metal research in all appropriate fields, publishing human and animal nutritional studies devoted to the fundamental chemistry and biochemistry at issue as well as to the elucidation of the relevant aspects of preventive medicine, epidemiology, clinical chemistry, agriculture, endocrinology, animal science, pharmacology, microbiology, toxicology, virology, marine biology, sensory physiology, developmental biology, and related fields.
