|The deleterious effects of cigarette smoking on trace elements concentrations are well known. Recent studies show that exposure of nonsmokers to environmental tobacco smoke (ETS) results in many biochemical processes and diseases. The aim of this study was to investigate the plasma concentrations of iron (Fe), zinc (Zn) and cooper (Cu) in 29 infants (14 boys and 15 girls, age range: 2-6 months, mean age: 3.6 months) who had been exposed to ETS (range 8-30 cigarettes/day mean 12.4 ± 4.7) for at least two months at home, while the control group included 30 infants (13 male, 17 female, age range: 2-6 months, mean age: 3.3 months) who had never been exposed to ETS. All infants had been breast fed. The plasma iron concentrations were determined by commercial kit, cotinine levels were determined by luminometric method. Cu and Zn concentrations were analyzed by atomic absorption spectrometry. The plasma Fe and Zn concentrations in the study group were significantly lower than in the controls (P < 0.05). However, plasma Cu levels were not different between the two groups (P > 0.05). In conclusion, the plasma Fe and Zn concentration decline in the ETS exposed infants.
