| Research Abstract |
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.
