Effect of formaldehyde exposure on pulmonary function tests of veterinary students in anatomy laboratory

This study evaluated the effect of formaldehyde exposure on pulmonary functions of veterinary students in the gross anatomy laboratory of Ferdowsi University, Mashhad, Iran. In total, 30 students (15 male, 15 female) were selected and examined before, in, and after gross anatomy dissection measuring pulmonary function tests: vital capacity (VC), forced vital capacity (FVC), peak expiratory flow (PEF), and forced expired volume in 1-s (FEV1). Data before, in, and after exposure for all students were analysed by 2-way analysis of variation tests using SPSS statistics software. The results showed formaldehyde decreased pulmonary function tests; in all students FVC decreased after gross anatomy dissection from 1.90 ( 0.39 to 1.74 ( 0.31 in males and 1.62 ( 0.21 to 1.58 ( 0.31 in females. A comparison of other lung function parameters (PEF, VC, flow rate at 50% of measured VC [F50]) showed significant differences between males and females; males had larger values than females (P <0.05). There was no significant difference in interactions between the sexes and exposure. Comparing other lung function parameters (FVC, FEV1, FEV [%], FER, F25) in males and females showed no significant differences.
