| 摘 要： | 锌是海水中有毒害的几个重金属痕量元素之一,在水体中以不同的形式出现.由于存在的形态不同,其所参与的生物、化学和地质过程不同,危害也就不同.因此,开展长江口海域锌的存在形式及其迁移规律的研究,不仅对研究海洋环境地球化学具有理论意义,而且为制定水质标准、发展海洋生产力提供科学依据等也具有十分重要的意义.

| Abstract: | Investigations of 11 stations in the Changjiang River estuarine area (30°50'-31°30'N and 121°50'-122°22'E) were made in April 1979.On board ship,we collected water and surface sediment samples,measured pH and temperature of the water,andp repared dissolved zinc and suspended particle zinc with millipore filter(0.45μm).In the laboratory,we analyzed 4 species of zinc.The ranges of concentration change are; 28-84 ppb for total zinc of liquid phase 8.8-46.3 ppb for free zinc,11.7-191 ppb for zinc of suspended phase,and 80.0-113.7 ppm for zinc of surface sediment; respectively. |
