将海胆精子尽可能完整地分成头部、中段和尾部，分别用分光光度法和原子吸收分光光度法测定了各部分中重金属铁、锌和铜的含量。铁的浓度是最高的中段馏分，而锌集中在尾部以及中段。仅在中段部分中发现铜。从尾部分离的微管也含有大量的铁和锌。
Sea urchin spermatozoa were fractionated into heads, midpieces and tails as completely as possible, and the contents of heavy metals, iron, zinc and copper, in these parts were determined both by spectrophotometry and by atomic absorption spectrophotometry. The concentration of iron was the highest in the mid-piece fraction, while zinc was concentrated in the tails as well as in the midpieces. Copper was found only in the midpiece fraction. Microtubules isolated from the tails also contained considerable amounts of iron and zinc.
