背景研究涉及对罐装金枪鱼、金枪鱼牛排、虹鳟鱼、熏鲭鱼、波罗的海和大西洋鳕鱼以及大西洋鲑鱼中铅、镉和砷的浓度进行调查。目的是抽查在波兰最常见的超市连锁店出售的最常购买的鱼类的质量，并确定可供零售的污染程度较低的鱼类来源。采用干灰化消化方案，然后进行 ICP-MS 分析，以便更好地从鱼肌肉组织中回收重金属和砷。结果鱼类肌肉组织中金属和砷的累积浓度从高到低依次为：养殖大西洋鲑鱼>鲭鱼>波罗的海鳕鱼>虹鳟鱼>罐头金枪鱼>大西洋鳕鱼>黄鳍金枪鱼排。研究发现，中太平洋和东太平洋的金枪鱼罐头比东印度洋和西印度洋的金枪鱼污染更严重，波罗的海鳕鱼的污染明显是东北大西洋的鳕鱼和东北太平洋的熏鲭鱼的 3 倍比来自北海北部的鲭鱼受到污染。除黄鳍金枪鱼牛排外，所有鱼类均不应零售，因为它们超过了 Cd 和 Pb 的最大含量 (ML)。结论仅食用一份（140 克）波罗的海鳕鱼可导致 51% 的每日 Cd 摄入量可接受，食用来自太平洋的罐装金枪鱼时为 69%，食用来自太平洋的烟熏鲭鱼时为 72%。来自北海的烟熏鲭鱼摄入的镉最多，高达每日可接受剂量的 162%。本文受版权保护。版权所有。

Content of toxic metals and As in marine and freshwater fish species available for sale in EU supermarkets and health risk associated with its consumption

BACKGROUND Research involved investigation of Pb, Cd and As concentrations in canned tuna, tuna steak, rainbow trout, smoked mackerel, Baltic and Atlantic cod as well as Atlantic salmon. The aim was to spot check the quality of the most commonly purchased type of fish which are available for sale in most common supermarket chains throughout the Poland as well as to determine potentially less contaminated sources of fish available for retail. Dry ashing digestion protocol followed by ICP-MS analysis was employed in order to obtain better recover of heavy metals and As from fish muscle tissues. RESULTS Cumulative concentration of metals and As in fishes' muscle tissue decreases in the descending order: farmed Atlantic salmon> mackerel>Baltic cod>rainbow trout>canned tuna fish>Atlantic cod>yellowfin tuna steak. It was found that canned tuna from Central and Eastern Pacific Ocean was more contaminated than tuna from East and West Indian Ocean, Baltic cod was significantly more contaminated that cod from North-East Atlantic and smoked mackerel from North-East Pacific Ocean is 3 times more contaminated than mackerel from Northern North Sea. All fish, except for yellowfin tuna steak, should not be intended for retail because they exceeds maximum levels (MLs) for Cd and Pb. CONCLUSION Consuming only one serving (140g) of Baltic cod results in 51% daily acceptable dose for Cd intake, 69% when eating canned tuna from Pacific Ocean and 72% when consuming smoked mackerel from the Pacific Ocean. The most cadmium is consumed with smoked mackerel from North Sea, as much as 162% of daily acceptable dosage. This article is protected by copyright. All rights reserved.
