天然湖水表面微层砷,磷酸盐,悬浮颗粒物及藻类富集现象的研究

本文利用自制的玻璃板表面微层水采样器采集并分析了天津水上公园湖水表面微层中砷的四种不同形态：亚砷酸盐、砷酸盐、一甲基刖酸盐、二甲基刖酸盐，以及溶解态总磷、总磷、县浮颗粒物和藻类的富集情况，初步探讨了它们在湖水表面微层富集的原因，结果表明，它们在湖水表面微层中均有不同程度的富集现象，其中以总磷、悬浮颗粒物和藻类尤为明显，它们在湖水表面微层的富集除了也大气物理运动过程的生物活动有关外，还与采样站位有关

STUDY ON THE ENRICHMENT PHENOMENON OF ARSENIC, PHOSPHORUS, SUSPENDED PARTICULATE AND ALGAE IN NATURAL LAKE WATER SURFACE MICROLAYER

The surface microlayer water samples were collected in the lake of Water Park in Tianjin and the enrichment phenomenon of four arsenic species (arsenite, arsenate, monomethylarsonate and dimethylarsonate), total dissolved phosphorus, total phosphorus , total suspended paniculate and the total amount of algae in the surface microlayer water was studied, and the reason for this was discussed preliminarily. Results showed that these matters were enriched in the lake water surface microlayer to different extent, especially for the total phosphorus, total suspended particulate and algae, and the enrichments of them in the lake water surface mircolayer were related to atmospheric, biological activity and sampling stations.
