自1990年7月~1991年5月取样测量了胶州湾东部各形态锡的季节序列变化。溶解无机锡、有机锡和颗粒态锡的百分比表明了锡形态分布的区域特征及可能的输入。丰水期(7月),各形态锡出现异常高值(DISn76.7ng/dm3,DOSn546.1ng/dm3,PSn688.6ng/dm3),表明陆源输入的主要作用。随着湾内海水盐度升高,溶解态无机、有机锡呈现外海低值的特征,但颗粒锡占据了绝对比例。极高的颗粒物富集因子(8.5×104~2.2×105)和浮游生物富集因子(5.1×104~7.0×105),说明水体锡的强颗粒物活性和生物获得性,对排除无机、有机锡起重要作用。相反,沉积物中锡的甲基化则将是锡从沉积转入水体的重要途径。
From July 1990 to May 1991, samples were taken to measure the seasonal variation of various tin species in the eastern Jiaozhou Bay. The percentage of soluble tin, organotin, and particulate tin is indicative of the regional characteristics of tin speciation and possible inputs. During the wet season (July), abnormally high values of DIS in various forms (DISn76.7ng / dm3, DOSn546.1ng / dm3, PSn688.6ng / dm3) indicate the main role of terrestrial input. With the increase of seawater salinity in the bay, dissolved inorganic state, organic tin presents the characteristics of low sea value, but the grain tin occupy the absolute proportion. The extremely high particulate matter enrichment factor (8.5 × 104 ~ 2.2 × 105) and the plankton enrichment factor (5.1 × 104 ~ 7.0 × 105) indicate the strong particulate activity and bioavailability of tin in water Sex, to exclude inorganic, organic tin plays an important role. In contrast, the methylation of tin in sediments will be an important route for the transfer of tin from sediment to body of water.
