Levels of trace metals (Cd, Cr, Cu, Fe, Ni, Pb, Mn, and Zn) were measured in soft tissues and external tubes of the Mediterranean fanworm, Sabella spallanzanii (Gmelin, 1791), to evaluate its suitability as a biomonitor of metal pollution. Study was conducted in the coastal area of the eastern Adriatic Sea. Polychaetes were collected from two locations, a site located in a local marina and an unpolluted control site. Results indicate that S. spallanzanii has the capacity to accumulate metals in soft tissues as well as in tubes. The levels of most metals were considerably higher in tubes compared to soft tissues, indicating long-term accumulation of metals in tubes. High levels of several metals (Cu, Zn, Cr, Pb and Fe), found in soft tissues and tubes sampled at the marina site, reflect the elevated contaminant levels in the marina, associated with the use of antifouling agents, paints, petrol additives, and ship maintenance activities. Metal concentrations in tissues and tubes generally decreased with size, indicating the influence of growth and metabolic rates on trace metal uptake. Trace metal levels found in S. spallanzanii tissues were comparable to the levels found in Mytilus galloprovincialis, a species commonly used in biomonitoring studies, in areas exposed to similar levels of anthropogenic stressors. According to the results of the present study, S. spallanzanii has been identified as a suitable biomonitor of metal pollution due to its sedentary nature, widespread distribution, abundance and the ability to accumulate high levels of metals within its tissues and tubes.
痕量金属（Cd、Cr、Cu、Fe、Ni、Pb、Mn 和 Zn）的水平在中肠动物扇虫 Sabella spallanzanii（Gmelin，1791）的软组织和外部管中进行了测量，以评估其作为金属污染生物监测器的适用性。该研究在亚得里亚海东部的沿海地区进行。多毛类动物分别从两个地点收集，一个地点位于当地码头，另一个为无污染对照点。结果表明，S. spallanzanii 有能力在软组织和管中积累金属。与软组织相比，大多数金属在管中的水平要高得多，这表明金属在管中存在长期积累。在码头地点采集的软组织和管中的几种金属（Cu、Zn、Cr、Pb 和 Fe）的含量较高，这反映了码头处污染物水平升高，这与防污剂、油漆、汽油添加剂和船舶维护活动有关。组织和管中的金属浓度通常随尺寸减小而降低，这表明生长和代谢率对痕量金属摄取的影响。在暴露于类似人为胁迫水平的地区，S. spallanzanii 组织中的痕量金属水平与贻贝 Mytilus galloprovincialis 中的水平相当，贻贝是生物监测研究中常用的物种。根据本研究的结果，S. spallanzanii 因其固着生活、广泛分布、丰富度和在其组织和管中积累高水平金属的能力而被确定为一种合适的金属污染生物监测器。
