Twenty samples of fish and seafood products were selected for determination of total and bioaccessible Se (i.e. soluble and dialyzable). The Se contents ranged between 0.638-0.052 µg/g. The samples of fatty fish such as mackerel and tuna showed higher contents than the species of lean fish, and mainly the fresh water fish, such as salmon, trout and panga showed the lowest contents. The fraction of soluble Se ranged between 43-84% while that the fraction of dialyzable Se did not exceed 14%. No statistically significant correlation was observed between protein content and total and bioaccessible Se content. In contrast, a negative interaction was observed between bioaccessible Se and fat content, and between bioaccessible Se and presence of heavy metals like Cd.
选取了20份鱼类和海产品样本，用于测定总硒和生物可利用硒（即可溶性硒和可透析硒）。硒含量在0.638 - 0.052微克/克之间。鲭鱼和金枪鱼等脂肪含量高的鱼类样本显示出比瘦鱼种类更高的含量，主要是鲑鱼、鳟鱼和淡水鲳等淡水鱼的含量最低。可溶性硒的比例在43% - 84%之间，而可透析硒的比例不超过14%。蛋白质含量与总硒和生物可利用硒含量之间未观察到统计学上的显著相关性。相反，生物可利用硒与脂肪含量之间以及生物可利用硒与镉等重金属的存在之间观察到负相关。
