摘要
通过对南极磷虾蜕壳前后甲壳和残壳中氟含量变化特征的分析 ,对南极磷虾富氟的原因进行了研究。结合其它资料 ,本文还对南极磷虾的富氟来源及机制进行了探讨。研究结果表明 ,南极磷虾蜕壳后的残壳对氟具有二次吸收的功能和作用 ,其对氟的富集存在着与生命活动无关的机理。氟的积聚不仅来自海水 ,且主要是以离子交换吸附的方式进行。
The Cause for the accumulation of fluoride in Antarctic krill is studied by the analysis of the characteristics of fluoride change in the cuticle of the krill before and after moulting. Associated with other related information, the source and accumulating mechanism of fluoride in krill are also disscussed. Results show that as an inorganic material the cuticle of krill has the second absorption function and action on fluoride after it is moulted, which has nothing to do with the living activity of the krill. The fluoride is accumulated from seawater, which is prosecutedmaily in the form of ion exchange.
