Blood levels of manganese and cobalt were analyzed with graphite furnace atomic absorption spectrophotometry in three groups of workers: non-exposed, middle-exposed and heavy-exposed to lead from five lead-acid battery factories located in Mexico City. Manganese levels were significantly higher in the heavy-exposed workers than in the non-exposed subjects. Cobalt in blood concentrations was found to be lowered in both middle and heavy exposed workers as compared to the control group. The significance of these findings is discussed in terms of the possible mechanisms underlying these observations.
采用石墨炉原子吸收分光光度法，对墨西哥城五家铅酸电池厂的三组工人（未接触铅、中度接触铅和重度接触铅）的血液中锰和钴水平进行了分析。重度接触铅的工人的锰水平显著高于未接触铅的受试者。与对照组相比，中度和重度接触铅的工人血液中的钴浓度均降低。根据这些观察结果背后可能的机制，对这些发现的意义进行了讨论。
