本文探讨了较高浓度的O_3对大鼠肺组织一些金属元素含量的影响。结果表明,肺重量、肺重/体重、及全肺Na含量,随暴露时间的延长而增加;全肺Ca、Cu含量变化的总趋势是暴露O_3后增加;全肺Zn、Mg、K含量于暴露O_38小时均增加,其后下降,但各组间无显著性差异;全肺Fe含量暴露后持续升高,但各组含量无显著性差异。 This article explored the effect of higher concentrations of O_3 on some of the metal elements in the lung tissue of rats. The results showed that lung weight, lung weight / body weight, and whole lung Na content increased with the prolongation of exposure time. The general trend of total Ca and Cu content in whole lung was increased after exposure to O 3; Exposure O_38 hours increased, then decreased, but no significant difference between the groups; whole lung Fe content continued to rise after exposure, but the content of each group was no significant difference.
