摘要
根据1980年6月,7月,9月,10月胶州湾水域调查资料,探讨和研究胶州湾重金属Hg的水质、平面分布、垂直分布、月变化以及污染源。结果表明：在胶州湾东部近岸,有三个Hg的重度污染源：海泊河、李村河和娄山河的河口区0.0832～13.04μg/L,在近岸水域有两个Hg的轻度污染源：薛家岛的两侧0.0637～0.134μg/L;在胶州湾近岸水域,其Hg的含量在0.030～0.050μg/L之间;胶州湾中心水域,其Hg的含量都低于0.030μg/L。胶州湾海域表层水和底层水中Hg含量分布的变化证实了Hg的迁移过程,表明了Hg入海后沉降较快,在胶州湾近岸水域沉降。通过胶州湾Hg污染的时空分布,认为人类活动造成Hg的污染,Hg污染的程度与采取的措施密切相关。因此,要治理胶州湾Hg的污染,首要的是采取措施控制陆源污染物的排放。
The investigation was carried out in Jiaozhou Bay waters in Jun. Jul. Sep. and Oct. 1980. The analysis of content, distribution, month change and pollution sources of Hg in Jiaozhou Bay were done. The results showed that in the eastern coast, there were three severe pollution sources 0. 0832 - 13.04 μg/L, three main rivers in the estuary into the sea, the Haipo, Licun, Lousha, and two light ones 0. 0637 - 0. 134 μg/L, the two sides of Xiejia Island. In the shore, the content of Hg was between 0. 030 - 0. 050 μg/ L, and in the center, that of Hg was below 0. 030 μg/L. The variations of Hg distribution in surface and bottom waters proved the transition process and showed that Hg into the sea quickly sank and settled down in the shore waters. Through the spaeial and temporal distribution, the fact was considered that human being resulted in Hg pollution, and the degree of Hg pollution was closely related with the taken steps. So, the first measures to control Hg pollution in Jiaozhou bay were to control the discharge of Hg pollutant from the land sources.
