氟污染对蔬菜的影响及其防治途径的研究

通过对上海市郊十个工厂附近的大气、降尘、水、土壤、蔬菜和人尿等生态因素含氟量的调查研究,证明各厂排放的氟化物对附近的蔬菜生产和人体健康都有不同程度的影响。其污染的严重程度与各厂的排放强度以及与厂外的距离有密切关系,并对污染源的治理、减少蔬菜的损失和保障人体的健康提山一些合理的建议。

STUDIES ON EFFECT OF FLUORINE POLLUTION ON VEGETABLE AND ITS CONTROL

Recently we have made an investigation on the ecosystem factors the fluoridescontents in air, dust, water, soil, vegetables and urine et al. near ten factorics in thesuburbs of Shanghai. It has proved that the fluorides emitted from these factories havevarious effects on the vegetables production and health of human being. The degree of the fluorides pollution depends, to a great extent, on the emissionintensity and the distance from the factory. The less efficiency of the environmentalprotection of the factories, the more severe effects on the field ecosystem. At theconclusion, we put forward some reasonable suggestions concerning how to solve thesource of pollution, how to decrease the loss of vegetables production and how toprotect the health of human being.
