Influence of density stratification on the dynamic behavior of high contaminated mercury at the mouth of Soca River in the Gulf of Trieste.

为了了解密度分层对的里雅斯特湾Soca河口高污染汞动力学行为的影响，进行了为期两年的现场水质观测和海水采样。研究结果表明：（1）由于Soca河径流的影响，海水和淡水之间经常出现明显的密度分层现象。(2)甲基汞的最大浓度出现在接近浅水层的地方。(3)甲基汞与水温、溶解氧的相关系数均达到显著水平。

In order to realize the influence of density stratification on the dynamic behavior of high contaminates mercury at the mouth of Soca River in the Gulf of Trieste, field observations on water quality and marine water sampling have carried out for two years. The obtained results are as follows ;(1) The density stratification between marine water and fresh water often occurs due to the runoff of Soca River significantly.(2) The maximum concentration of methyl-mercury appears close to hypolimnion.(3) The correlation coefficients between methyl-mercury and water temperature, dissolved oxygen are significant.
