In the present study, adult Wistar albino male rats were exposed to formaldehyde at different periods (subacute and subchronic)
and concentrations (5.0 and 10.0 ppm) in order to figure out the changes in the concentration of Zn, Cu and Fe. It was observed
that the formaldehyde inhalation caused gradual decline of body weights in the experimental groups when compared with control
groups. It was found that subacute (4-week) or subchronic (13-week) exposure to formaldehyde for rats may cause growth retardation.
After inhalation procedure, concentration of copper, zinc and iron were determined in liver and kidney tissues of rats using
atomic absorption spectrophotometer. In addition, concentrations of Cu, Zn and Fe changed by the effect of formaldehyde in
subacute and subchronic groups. 相似文献

The levels of zinc, copper, iron, and manganese were measured in the hippocampus, thalamus, gyrus cinguli, hypothalamus, and
in the prefrontal, parietal, temporal, and occipital cortexes of lamb brain by flame atomic absorption spectrometry. Standard
addition method was also applied to samples and it was observed that there was no matrix interference affecting the determination
of elements interested. In the determination of Cu, a slotted tube atom trap was used to improve sensitivity. One-way analysis
of variance was used for the statistical evaluation of the results for each element. Limit of detection results for Zn, Cu,
Fe, and Mn were found to be 24, 4.5, 60, and 25 ng/mL, respectively. Region-specific differences were found for all elements
interested. Mn concentration ranging from 0.29 ± 0.04 to 0.61 ± 0.04 mg/kg was found to be the lowest in all brain regions
among the all elements interested. 相似文献
