Abstract The contents of major elements and micronutrients of the kelps, macroalgaes produced in the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea, were respectively determinated. Their differences in nutrient contents between regions were compared,and their ability to eliminate the excessive nitrogen and phosphorus in sea waters were analyzed. The results showed that the concentrations of nitrogen, phosphorus and iodine in the kelp were respectively 9.8×104 times, 2.0×105 times, and 5.8×104 times higher than that in the sea water. Meanwhile, the organic iodine fertilizer made from the kelp was applied to cultivate iodine-rich vegetables, and their iodine content could reach to about 10 times higher than the unfertilized controls. The biogeochemical process of using exogenous iodine to improve the iodine deficiency in the soil was revealed. At last, a kelp-based potential model to repair the ecological environment is established, which can link the remediation of eutrophic sea waters and the improvement of inland environment of iodine deficiency. The solution may provide a technical route to establish an environment-friendly iodine industry chain, including large-scale cultivation of kelps, extraction of biomass energy from kelp fermentation, manufacture of organic iodine fertilizer, cultivation of iodine-rich plant foods, and so on.
