在胚胎发育过程中,用不同比放射性的~(90)锶试液处理受精卵,各处理组都有畸形和死亡现象。畸形的高峰一般出现在囊胚期和晶体形成期,畸形的类型一般为脊椎弯曲、体短、胸腔和卵黄囊扩大,头和眼畸形。随后即出现死亡高峰。例如:游动期的死亡率分别是:21%(对照);36%(5×10~(-11)居里/升);40%(5×1-~(-10)居里/升);45%(5×10~(-9)居里/升)。鲫仔鱼对~(90)锶吸收积累的结果表明:鲫仔鱼体中比放射性大小与试液的比放射性大小成正比,并随试验吋间的延长,生物量的增加而增加,鲫仔鱼的积累系数则不依试液的比放射性大小和生物量的多少为转移。
During embryonic development, the fertilized eggs were treated with different specific radioactive (90) strontium test solutions, and all treatment groups had deformities and deaths. Deformity peak usually occurs in the blastocyst stage and the formation of crystals, the type of deformity is generally spine bending, short body, chest and yolk sac expansion, head and eye deformities. Then there is the peak of death. For example, the mortality rates during ambulation were 21% (control), 36% (5 × 10-11) and 40% (5 × 1--10) ); 45% (5 × 10 -9 Curie / liter). The accumulation of strontium (90) in the crucian carp showed that the specific radioactivity of the larvae of the crucian carp was proportional to the specific radioactivity of the test solution and increased with the increase of the test time and biomass, Coefficients do not depend on the specific radioactivity of the test solution and the amount of biomass as the transfer.
