韩国有专家指出,散布黄土作为目前防制赤潮的唯一方法,从长远来看,反而会促进赤潮的发生。同时指出,撒布黄土时,黄土粒与赤潮生物相结合,沉淀到海底,从而取得一时性的防制效果。但是,在长时间内,会产生由海底的黄土微粒子构成的黏液质,导致低质土酸性化。一旦低质土酸性化,就会产生促进赤潮生物增殖的铁、锰等无机物和氨基酸、胺等有机物,这些物质,都有助于赤潮生物的产生,因此,就会形成恶循环。还提到说,利用西海岸一些实施渔船报废制度的地方的黄土建立防洪工程时,1～2年内临近海域的贝类会大量生
Some experts in South Korea pointed out that spreading loess as the only method for controlling red tides at present will, in the long run, actually promote the occurrence of red tides. At the same time, it is pointed out that when spreading loess, loess particles combine with red tide organisms and sediment to the seabed so as to achieve temporary control effect. However, for a long period of time, a mucilaginous material composed of seabed loess particles is generated, resulting in the acidification of low quality soil. Once the low-grade soil is acidified, inorganic substances such as iron and manganese and organic acids such as amino acids and amines will be produced to promote the proliferation of red tide organisms. All of these substances contribute to the production of red tide organisms and thus form a vicious cycle. Also mentioned that the use of some of the West Coast fishing vessels to implement the system where the loess flood control project to establish, 1-2 years of shellfish near the sea will be a large number of students
