[1]王寿祥,张永熙,陈传群,孙志明,黄丹,胡秉民.~(89)Sr在模拟陆生-水生生态系中的行为[J].核技术,1994(01):54-58.
Behaviour of  ̄(89)Sr in simulated land- aquatic ecosystem[J]. Nuclear techniques, 1994, (1).
研究了(89)Sr在陆地作物菜豆中的积累动态及对水体的影响。结果表明,土壤中的(89)Sr较迅速地向菜豆转移,其比活度与时间成指数正相关,而土壤中(89)Sr的比活度与深度呈指数负相关。通过雨水淋溶和渗漏,土壤中的(89)Sr约5%进入水体;水体内各组分的分配为池水较低,底泥较高;而水生生物中金鱼藻较低,鱼和螺蛳中最高,表现了鱼和螺蛳对水体中的(89)Sr有较大的浓集作用。
The accumulative dynamic of 89Sr in the kidney bean and its effect on the waters were studied. It is shown that 89Sr would tyansfer to kidney beau rapidly and the accumulation of 89Sr in the kidney beau follows a positive exponential relation with time
but follows a negative exponentical relation with depth of the soil. After the soil was leached and seeped by rain
the 89Sr would enter into waters for 5% and be distributed to each component of waters. The specific activity of 89Sr was low in the waters and honewort
high in the bottom mud
and highest in the fish and snail
showing that fish and snail can strongly concentrate 89Sr in waters.
