Fatty acid (FA) and element contents were studied in 14 brands of canned (in its own juice and with sunflower oil) saury (Cololabis saira), a popular product of Russian market. Canned saury is a valuable source of essential polyunsaturated FA - eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3). To obtain personal daily dose of EPA + DHA of 1 g for prevention of cardiovascular diseases, neural and inflammatory disorders one needs to intake from 26 to 76 g of canned saury, as was calculated for studied brands. ICP-OES analysis of 24 elements showed that Pb concentration in one brand and Cd content in most of studied saury samples exceeded standards for fish meat established by the European Commission. However, values of hazard quotient, HQ which estimate benefit-risk ratio of fish intake, indicate that canned saury is safe product for human nutrition.
对俄罗斯市场上一种受欢迎的产品——14个品牌的罐装秋刀鱼（Cololabis saira，有原汁和添加葵花籽油两种）的脂肪酸（FA）和元素含量进行了研究。罐装秋刀鱼是必需多不饱和脂肪酸——二十碳五烯酸（EPA，20:5n-3）和二十二碳六烯酸（DHA，22:6n-3）的宝贵来源。为预防心血管疾病、神经和炎症性疾病，要获得1克EPA + DHA的个人每日剂量，对于所研究的品牌，需要摄入26至76克罐装秋刀鱼。对24种元素的电感耦合等离子体发射光谱分析表明，一个品牌的铅浓度以及大多数所研究秋刀鱼样本中的镉含量超过了欧盟委员会规定的鱼肉标准。然而，用于评估鱼类摄入效益风险比的危害商数（HQ）值表明，罐装秋刀鱼是人类营养的安全产品。
