摘要
水产养殖产品因其健康成分而成为人类营养的重要组成部分;然而,它们可能含有对消费者具有潜在毒性的元素。本研究旨在通过电感耦合等离子体光发射光谱法检测意大利一家水产养殖场养殖的虹鳟鱼(Oncorhynchus mykiss)体内的砷、镉、汞和铅含量。砷的含量为 1.65 ± 0.49 毫克/千克;但由于缺乏官方规定,无法对砷总量进行评估。计算得出的无机砷含量 EDI 和 THQ 均低于参考值。30% 样本的镉含量高于规定限值,但其 EDI 和 THQ 均低于建议限值。所有样本中的汞含量都低于规定的最高限值。10% 的样本中检测到的铅含量高于最高限值,但其 EDI 和 THQ 均低于参考剂量和建议值。尽管镉和铅的含量高于官方规定的上限,但成人的 HI 值低于 1;因此,食用所调查的虹鳟鱼是安全的,但儿童的 HI 值则高于官方规定的上限,因此会有轻微风险,尤其是长期食用。
Possible Metal Burden of Potentially Toxic Elements in Rainbow Trout (Oncorhynchus mykiss) on Aquaculture Farm
Aquaculture products are important parts of human nutrition due to their healthy components; however, they may contain elements that are potentially toxic to consumers. The aim of the study was to detect the concentration of As, Cd, Hg, and Pb by inductively coupled plasma optical emission spectroscopy in rainbow trout (Oncorhynchus mykiss) originated from an aquaculture farm in Italy. The amount of As was 1.65 ± 0.49 mg/kg; however, the total As cannot be evaluated due to the absence of official regulation. The calculated EDI and THQ for the inorganic As content were below the reference values. The level of Cd was higher than the regulated limit in 30% of the samples; however, its EDI and THQ were below the recommended limit. The concentration of Hg was below the regulated maximum limit in all the samples. The detected amount of Pb was above the maximum limit in 10% of the samples; however, EDI and THQ were below the reference dose and recommended value. Despite higher concentrations of Cd and Pb than the official regulated limit, HI was below 1 for adults; thus, the consumption of the investigated rainbow trout is safe, but it was above the official regulated limit for children, resulting in a slight risk, particularly during long-term intake.
