Methods: For this purpose newly born albino Wistar rats were exposed to 0 ( control), 6 or 12 ppm FA gas for 30 days. After the treatment, rats were decapitated in 30th and 90th days. Activities of t-SOD and the levels of zinc, copper and iron were measured in lung samples. Results: A decrease in the t-SOD activity, copper and iron levels and increase in zinc levels were found in the treatment groups in comparison with control group at both 30th and 90th days measurements. Conclusion: It was thought that exposure to FA may alter the trace element levels of lung tissue including copper, zinc and iron, and induce further oxidative damage on lung tissue.eninfo:eu-repo/semantics/openAccessFormaldehyde gaslungt-SODzinccopperironArticle22626810.29333/ejgm/822712-s2.0-28844503271N/AWOS:000421855400004N/A
