Resumo
Background: Some raw materials applied in Fe foundry industries may contain potentially toxic elements. Thus,
foundry worker’s occupational exposure is a constant health concern.
Method: In this study, 194 urine samples from foundry workers were analyzed by inductively coupled plasma
mass spectrometry for biomonitoring of Al, As, Ba, Cd, Co, Cr, Cs, Cu, Fe, I, Mn, Ni, Pb, Sb, Sn, Se, U and Zn.
Moreover, arsenic speciation was performed in representative samples of production sector workers (group A)
and administration sector workers (group B).
Results: Concentrations of As, Pb, Cd, Cu, Cs, I, Sb in urines from group A were higher than those found for group
B. Samples of group A presented Cs, Ni, Mn, Pb, U and Zn concentrations higher than values reported for exposed
workers assessed by other studies. Forty-four samples from group A exceed As-reference limits. Group A had
approximately seven times more inorganic As (as arsenite) and 14 times more organic As (as dimethyl As) than
group B. A statistically significant difference was observed in the elemental concentration in the workers' urine
by the time in the function. Moreover, alcohol consumption is probably influencing the urine concentration of
As, Ba, Cd, Co, Cu, Fe, I, Se and Zn.
Conclusion: The monitored foundry workers are exposed to potentially toxic elements and more attention must
be given to their health. Therefore, workplace safety conditions must be improved, and constant biomonitoring
is necessary to ensure workers' health.
