Following aspects are considered in this paper in order to outline recent research advances of the flux of chemical species exchange between air and sea:(1) Without chemical reactions, typical flux-gradient relationship(K theory) may be adopted to estimate the flux from air to sea. Otherwise, the K theory should be modified according to the relative speed of reactions and turbulence. (2) In another way, the flux can be represented by the multiplication of concent ration at sea surface and the deposit velocity. Precipitation has much contribution to the removal of chemical species from air. Parameterization of the physical process of precipitation influences directly the magnitude of wet deposition flux. (3) Gas transfer is often expressed with the gas transfer coefficient and the partial pressure difference between air and water. The flux equals the multiplication of these two terms. All the two parameters can influence the accuracy of the flux estimation.
