| Abstract: | Experiments on acidity,proportion of raw materials,temperature and precipitation conditions arc made in the production of Citric acid rare earth as feed, and RE2O3 and some poisonous elements such as Pb,As,Cd and Hg etc. are detected in the article. The product is proved to be non Anpoisonous and have no remains through tests of acute animal toxicologic experiments and accumulation experiments. Therefore,the article provides some scientific basis for its use in aquaculture. |
