Abstract

Fish are good bio-indicators of the health status of the aquatic environment and can be used as biomarkers to assess the aquatic behavior of environmental pollutants, the exposure of aquatic organisms, and the health risk for consumers. Goldfish are a significant bioindicator in the Lake Trasimeno aquatic system (Umbria, Italy). This study aimed to characterize the health status and the chemical and biotic contamination of Lake Trasimeno to define its anthropogenic and natural pressures and the risk associated with consuming its fishery products. 114 determinations were performed on Carassius auratus samples from 2018 to 2020, and the occurrence of brominated flame retardants, non-dioxin-like polychlorinated biphenyls, heavy metals, and microplastics was analytically investigated. Dietary exposure assessment, risk characterization, and benefit-risk evaluation were performed for schoolchildren from 3 to 10 years old. Flame-retardants registered high levels of non-detects (99% for polybrominated diphenyl ether and 76% for hexabromocyclododecanes), while polychlorinated biphenyls were found in all samples with a maximum level of 56.3 ng/g. Traces of at least one heavy metal were found in all samples, though always below the regulatory limit. Microplastics were found with a 75% frequency of fish ingesting at least one particle. Dietary exposure and risk characterization reveal negligible contributions to the reference values of all contaminants, except for mercury, which reached up to 25% of admissible daily intake. The benefit- risk assessment highlighted that the benefits of freshwater fish intake outweigh the associated risks. The examination of goldfish as indicator fish reveals the quality of Lake Trasimeno's aquatic environment and the safety of its products.

异育银鲫作为特拉西梅诺湖健康状况的生物指标及消费者风险评估。
鱼类是良好的水生环境健康状况的生物指标,可作为评价环境污染物的水生行为、水生生物暴露和消费者健康风险的生物标志物。金鱼是意大利翁布里亚特拉西梅诺湖水生系统中重要的生物指示物。本研究旨在描述特拉希梅诺湖的健康状况和化学和生物污染,以确定其人为和自然压力以及与消费其渔业产品相关的风险。2018 - 2020年对鲫鱼样品进行了114次检测,分析了溴化阻燃剂、非二恶英样多氯联苯、重金属和微塑料的含量。对3至10岁的学龄儿童进行了膳食暴露评估、风险表征和收益-风险评估。阻燃剂未检测到的含量很高(多溴联苯醚为99%,六溴环十二烷为76%),而多氯联苯在所有样品中均被发现,最高水平为56.3纳克/克。在所有样品中都发现了至少一种重金属的痕迹,尽管总是低于规定的限制。鱼类摄入至少一种塑料微粒的频率为75%。饮食暴露和风险特征表明,除了汞外,所有污染物对参考值的贡献可以忽略不计,汞达到每日可接受摄入量的25%。利益-风险评估强调,淡水鱼摄入的好处大于相关的风险。金鱼作为指示鱼的检测,揭示了特拉西梅诺湖的水环境质量及其产品的安全性。
