This study investigates the seasonal variations in the elemental composition of five economically valuable fish species from Bozcaada, North Aegean: red seabream (), gilthead seabream (), saddled seabream (), white seabream (), and common dentex (), with a focus on both essential minerals and toxic metals. Fish samples ( = 10 per species per season) were collected across four seasons, and their weights and lengths were recorded. The concentrations of elements such as calcium, potassium, magnesium, phosphorus, copper, iron, manganese, zinc, chromium, nickel, selenium, cadmium, and mercury were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The elemental concentrations varied as follows: Ca (11,388.46-55,470.76), K (17,230.83-27,594.86), Mg (1436.02-2326.73), Na (1962.30-7847.41), P (13,112.11-15,516.57), Fe (107.61-282.00), Cu (36.44-59.13), Mn (6.19-19.87), Zn (98.67-256.26), Cr (4.54-11.96), Ni (6.33-13.89), Se (0.82-7.33), Cd (0.08-0.32), and Hg (0.08-1.50) mg/kg. Health risk assessments, including Estimated Weekly Intake (EWI), Target Hazard Quotient (THQ), and Cancer Risk (CR), were calculated for both adult and child consumers. The results showed that while the essential minerals remained within safe limits, seasonal variations in the concentrations of toxic metals could pose potential health risks, particularly with frequent consumption. This research provides valuable insights into balancing the nutritional benefits and safety of fish from Bozcaada, offering recommendations for informed consumption and public health policies aimed at optimizing benefits while minimizing risks.
本研究调查了北爱琴海博兹贾阿达的五种经济价值较高的鱼类品种的元素组成的季节性变化，这五种鱼分别是：真鲷、银头鲷、鞍带石斑鱼、白鲷和斑鳍鲷，重点关注必需矿物质和有毒金属。在四个季节中收集了鱼类样本（每个品种每个季节 = 10 个），并记录了它们的重量和长度。使用电感耦合等离子体质谱法（ICP-MS）分析了钙、钾、镁、磷、铜、铁、锰、锌、铬、镍、硒、镉和汞等元素的浓度。元素浓度变化如下：钙（11,388.46 - 55,470.76）、钾（17,230.83 - 27,594.86）、镁（1436.02 - 2326.73）、钠（1962.30 - 7847.41）、磷（13,112.11 - 15,516.57）、铁（107.61 - 282.00）、铜（36.44 - 59.13）、锰（6.19 - 19.87）、锌（98.67 - 256.26）、铬（4.54 - 11.96）、镍（6.33 - 13.89）、硒（0.82 - 7.33）、镉（0.08 - 0.32）和汞（0.08 - 1.50）mg/kg。针对成年和儿童消费者计算了健康风险评估，包括估计每周摄入量（EWI）、目标危险商数（THQ）和癌症风险（CR）。结果表明，虽然必需矿物质仍在安全范围内，但有毒金属浓度的季节性变化可能会带来潜在健康风险，尤其是频繁食用时。本研究为平衡博兹贾阿达鱼类的营养益处和安全性提供了有价值的见解，为明智消费和旨在优化益处同时最小化风险的公共卫生政策提供了建议。
