二氧化锡（SnO2）在工业上有广泛的用途，如锡盐制造、涂料配制、玻璃、塘瓷、电子工业等[1]。为保护作业工人身体健康，受国家劳动卫生标准分委会的委托，我们承担了车间空气中SnO2卫生标准研究，现将SnO2毒理学实验研究结果报告如下。1．材料和方法1．1动物选用BALB／C小鼠， Tin oxide (SnO2) has a wide range of industrial applications, such as tin salt manufacturing, paint preparation, glass, Tang porcelain, the electronics industry [1]. In order to protect the health of workers, commissioned by the National Labor Standards Committee, we undertake the study on the health standards of SnO2 in the air of the workshop. The results of the experimental study on the toxicology of SnO2 are reported as follows. 1. Materials and methods 1.1 animal selection BALB / C mice,
