The macroelement (sodium, potassium, calcium and magnesium) concentrations have been determined in various tissues of the Common Pacific squid, Loligo opalescens. The method of measurement was flame atomic emission (sodium and potassium) and absorption (calcium and magnesium) spectrometry. Edible tissues such as the tube (mantle), arms and crown, and fin contained: from 3.3 +/- 0.4 to 3.9 +/- 1.5 (1.9-6.8) g/kg wet weight of sodium; from 5.3 +/- 0.6 to 6.3 +/- 2.7 (3.3-14) g/kg of potassium; 38 +/- 7 to 100 +/- 34 (28-200) mg/kg of calcium; and from 510 +/- 100 to 950 +/- 280 (340-1500) mg/kg of magnesium. The other tissues or organs examined frequently contained a higher concentration of macroelements than the edible flesh. Statistically significant correlations between the body weight of squid and macroelement concentrations or between some pairs of metals in whole squid, mantle and hepatopancreas have been observed.
已测定了太平洋褶柔鱼（Loligo opalescens）各组织中的常量元素（钠、钾、钙和镁）浓度。测量方法为火焰原子发射光谱法（用于钠和钾）和吸收光谱法（用于钙和镁）。可食用组织，如胴体（外套膜）、腕和头、以及鳍，每千克湿重含：3.3±0.4至3.9±1.5（1.9 - 6.8）克钠；5.3±0.6至6.3±2.7（3.3 - 14）克钾；38±7至100±34（28 - 200）毫克钙；以及510±100至950±280（340 - 1500）毫克镁。所检查的其他组织或器官通常比可食用鱼肉含有更高浓度的常量元素。已观察到柔鱼体重与常量元素浓度之间，以及整个柔鱼、胴体和肝胰腺中某些金属对之间存在统计学上的显著相关性。
