The article presents a study which seeks to determine the effects of root metabolism on the post-depositional mobilization of mercury in salt marsh soils. The researchers have chosen the salt marshes in Sepetiba Bay in Brazil, as site for the study. They carefully investigated, the metabolism of salt marsh plants and found that it could affect the mobilization of mercury in salt marsh soils. The study revealed that exudation of oxygen during root metabolism of salt marsh plants was one factor that mobilize deposited mercury in salt marsh soils. Hence, the development of permanent reducing conditions, as well as the immobilization of mercury will be avoided because of the root metabolism.
