厦门河口港湾区海水中90Sr的行为特征研究
Behavior and characteristics of 90Sr in Xiamen estuarine and harbor area
【摘要】 本文以厦门港西海域中的90Sr为研究对象,目的在于阐明90Sr在河口港湾区的行为特征及迁移规律。结果表明,90Sr在厦门河口港湾区表层海水中的含量范围为:丰水期介于(2.10±0.09)~(3.79±0.04)mBq/L之间,枯水期介于(4.10±0.41)~(5.30±0.05)mBq/L。90Sr在河口区的浓度较其他区域低。在本海域中90Sr的浓度随着远离河口方向有逐渐增加的趋势,盐度与90Sr含量正相关。
【Abstract】 90Sr in the west area of Xiamen Harbor and Jiulong Estuary was studied.The content of 90Sr in the surface sea water of Xiamen port was similar with in East sea measured by SOA.It ranges from 2.10±0.09 to 3.79±0.04mBq/L in rain season,and 4.10±0.41 to 5.30±005mBq/L in dry season.The content of 90Sr was lower in the estuary than other area.With the distance of the esturies increase.The concentration of 90Sr is increase with the increase distance in the estuary.
