During the conduct of autopsies performed on residents of Mexico City during the 1960s (20 males, 19 females) and 1990s (30 males and 18 females), concentrations of manganese in lung were studied with atomic absorption spectrometry. Concentrations of manganese were not significantly greater in the samples obtained in the 1990s (1.87+/-0.8 microg/gm [mean +/- standard deviation]) than in samples from the 1960s (1.72+/-1.2 microg/gm). Concentrations were not correlated with gender, smoking habit, age, or cause of death; however, there was a correlation with occupation. The findings suggest that manganese exposure via air does not represent a health hazard to residents of Mexico City, given that lung concentrations of manganese remained stable during the 30-y period studied. Investigators should monitor concentrations of manganese in suspended particles to follow-up on these findings.
在对20世纪60年代（20名男性，19名女性）和90年代（30名男性和18名女性）墨西哥城居民进行尸体解剖的过程中，使用原子吸收光谱法研究了肺中锰的浓度。20世纪90年代获得的样本（1.87±0.8微克/克[平均值±标准差]）中的锰浓度并不比20世纪60年代的样本（1.72±1.2微克/克）显著更高。浓度与性别、吸烟习惯、年龄或死因均无关联；然而，与职业存在相关性。研究结果表明，鉴于在所研究的30年期间肺中锰的浓度保持稳定，通过空气接触锰对墨西哥城居民并不构成健康危害。研究人员应监测悬浮颗粒中锰的浓度以追踪这些研究结果。
