油页岩可作为提炼石油之用,其灰渣已成为“三废”,但用它来改良粘性土壤可获水稻增产25％左右。为了探讨稻米是否受污染和对人体的远期作用,进行了毒性实验。 实验方法:①用按施放页岩灰不同量(以吨/亩计)2、4、6,种植的稻米喂饲实验组大白鼠,用不施放页岩灰种植的稻米喂饲对照组;②试验动物用健康高乳Wistas Oil shale oil can be used as refining purposes, the ash has become “three wastes,” but use it to improve the cohesive soil available rice yield increase of about 25%. In order to investigate whether rice is contaminated and its long-term effect on human body, toxicological experiments were conducted. Experimental methods: (1) The rats in experimental groups were fed with different amounts of shale ash (in tonnes / mu), 2,4,6 and the planted rice, and the rats in the control group were fed with rice not shale ash planted; Test animal healthy high milk Wistas
