铍对动物的毒性研究大都采用吸入染毒法。小剂量长期经口进入机体的研究,只见到、Schroder和Mitchener的报道。为修订铍在地面水中最高容许浓度提供科学依据,我们进行了铍的急性、慢住、蓄积性和诱变性研究,结果如下: 动物用Wistar大鼠和封闭群小鼠。硫酸铍为国产化学试剂,水不溶物<0.1％。染毒方式为消化道染毒。将硫酸铍配成不同浓度的水溶液,供动物自由饮用或灌胃(一次或多次)。
Most beryllium toxicity studies on animals using inhalation exposure method. Small doses of long-term oral into the body of the study, only to see, Schroder and Mitchener reports. To provide a scientific basis for revising the maximum allowable concentration of beryllium in surface waters, we conducted an acute, slow-living, storage and mutagenic study of beryllium with the following results: Wistar rats and closed mice in animals. Beryllium sulfate for domestic chemical reagents, water insoluble <0.1%. The way of exposure to the digestive tract. Beryllium sulfate formulated into different concentrations of water for animals to drink freely or gavage (one or more times).
