Presentation of a Model Simulating the Response of Lakes to Fertilizations to Reduce Radiocesium Levels in Fish

摘要

Lake fertilization is a potential remedy for toxic contamination in lakes with low productivity, which are known to be sensitive to, e.g. radionuclides, metals and organic toxins. This study presents a model to plan the duration and predict the outcome of fertilization in lakes. Several methods of lake fertilization have been used in field experiments: (1) Lake and wetland liming using 'mixed' lime with added phosphorus; (2) treatment with commercial fertilizers; and (3) using effluents (containing phosphorus) from fish farms.
