Abstract

Harvesting of marshfire glasswort (Salicornia europaea) by local people has been increased recently since this plant was known for a well-being food. Even though some harvesting sites are facing high risk of environmental pollution, Salicornia europaea is still harvested on a large scale. Therefore, to investigate safety of Salicornia europaea as a food resource, salt marsh environment, potential harvestable biomass, element and heavy metal accumulations in Salicornia europaea has been studied in three salt marshes, west-coast of Korea. Salicornia europaea showed 150 - 230$g/m^2/yr$ harvestable biomass. Biomass and nitrogen contents of Salicornia europaea were closely related to soil nitrogen and carbon concentrations. Average Na, Zn, Fe, Cr accumulations in Salicornia europaea were 41479, 18, 297, 1.5 (mg/kg), indicating valuable trace element contents. However, average heavy metal accumulations such as As, Cd, Cu, Pb, Hg accumulations were 1.5, 7.1, 4.2, 1.5, 0.1 (mg/kg), which were even or higher than national standards (0.5, 0.5, 2, 2, 0.1) of salts. These results imply that harvesting and eating of Salicornia europaea in west-coast research sites would be harmful because the contents would be much higher if it is calculated as only considering salts and minerals. Therefore, harvesting of Salicornia europaea from some salt marsh in west-coast of Korea should be done cautiously.
