水中钡的卫生标准的探讨

本文对有关水中钡的毒性和标准的文献进行了复习和讨论。对钡的毒性和标准意见不一。有认为钡高至250mg／1无不良影响，而有的认为10mg／1以上即有毒性。我们的试验电得到类似后者的结果。建议饮水中钡的卫生标准订为0．1mg／1。地面水中钡的最高容许浓度为1mg／1。

DISCUSSION ON THE SANITARY STANDARD OF BARIUM IN WATER

This paper reviewed the research works of the toxicity and the standard of barium in water. The results were quite different. Some authors considered that the barium level in water up to 250mg/1 had no adverse effects. But other authors considered that the barium level in water over 10 mg/1 appeared toxicity. Our study was similar to later. We proposethat the sanitary standard of barium in drinking water is 0.1mg/1, and the maximum allowable concentration in surface water is 1 mg/1.
