莱州湾海水中U的不均匀分布规律及地球化学研究

GEOCHEMISTRY AND DISTRIBUTION REGULARITY OF URANIUM IN THE LAIZHOU BAY

本文报道了1984年和1987年莱州湾海水中U分布规律的调查研究结果。发现莱州湾海水中U存在着不均匀分布规律,其不均匀分布主要受黄河水高浓度U入海扩散、稀释的影响和控制;雨季,也受到附近河流输入的一定影响。调查结果说明,莱州湾海水中U浓度普遍较高,但尚未构成对海洋生物污染的影响。初步论证了莱州湾海水中U对形成沿岸地下浓缩海水高U浓度的影响。

This study carried out in 1984-1987 shows that uranium concentration in the Laizhou Bay is high. Its principal cause is related to the high uranium concentration of the Hu-anghe River that discharges its load into the bay. The discharge of Huanghe River, varies seasonally, resulting in distribution irregularity of uranium. Relationship between uranium and salinity is in inverse relation. The level of uranium content does not affect the aqua-culture. Uranium is mostly concentrated in underground seawater of Laizhou Bay.
