Materials And Methods.

[Aluminium in the lower respiratory tract of people living in México City].

Objective: Investigating the presence of aluminium (Al) and respiratory pathologies in the lower respiratory tract of people who had lived in Mexico City for a minimum of two years.

Methods: 250 respiratory tissue samples were obtained from pulmonary lobes, lymph nodes, bronchial and hilum regions during 36 individuals' autopsies. Inductively coupled plasma optical emission spectrometry (ICP-OES) was used for quantifying Al; the samples has been previously dried, ground and digested.
