In this paper, the origins of mercury and the advances in the study of morphology and morphological analysis of mercury are reviewed, and the main factors that affect the adsorption and desorption of mercury are discussed. Some measures to control mercury pollution in soil/sediment, such as bioremediation, reducing mercury pollution from emissions, are put forward. The advantages and shortcomings of several risk assessment methods of mercury pollution in soil/sediment are compared with each other, and the prospects of the study of geochemical behaviors of mercury in soil/sediment are also dealt with.
