对胶州湾水体、浮游生物、悬浮颗粒物和沉积物中锡的测定、形式、生物累积等进行研究。不同季节(1987年和1988年)的水体、浮游植物和沉积物测定表明:1.水体总还原无机锡和总锡含量分别为4.2～38.8ng/dm~3,65.6～209ng/dm~3;浮游植物总锡含量为22.4～414mg/kg(干重);沉积物总锡含量为0.015～0.98mg/kg(干重),且在胶州湾港口区测得水体总锡的最大值209ng/dm~3。以上结果与目前世界其它海域、河口类似。2.有些区域有机锡含量已达到或超过某些生物的致毒阈值(对双壳类,其TBT≤0.1μg/dm~3)从而引起水质恶化。3.水体总锡含量与悬浮颗粒量密切相关;浮游植物对锡的生物富集因子高达10~5,说明无机或有机颗粒及生物体在水体锡的循环迁移过程中起重要作用。
In Jiaozhou Bay waters, plankton, suspended solids and sediment determination of tin, form, bio-accumulation and so on. The measurements of water bodies, phytoplankton and sediments in different seasons (1987 and 1988) showed that: 1. The total inorganic tin and total tin contents in the total water bodies were 4.2 ~ 38.8ng / dm ~ 3 and 65.6 ~ 209ng / dm ~ 3, respectively; The total amount of tin in the phytoplankton ranged from 22.4 to 414 mg / kg (dry weight); the total tin content in the sediments ranged from 0.015 to 0.98 mg / kg (dry weight), and the maximum value of total tin in the water was 209 ng / dm ~ 3. The above result is similar to other sea areas and estuaries in the world at present. 2. In some areas, the organotin content has reached or exceeded the lethal threshold of some organisms (TBT≤0.1μg / dm ~ 3 for bivalves), causing water quality deterioration. The total amount of tin in water is closely related to the amount of suspended particles. The bioconcentration factor of phytoplankton to tin is as high as 10-5, indicating that inorganic or organic particles and organisms play an important role in the cycling of tin.
