title: Excruciating effect of formaldehyde exposure to students in gross anatomy dissection laboratory.
abstract: BACKGROUND
  Formaldehyde is extensively used for preservation of cadavers in departments of anatomy. However, it is a noxious chemical which may cause serious health problems.
  
  
  OBJECTIVE
  To assess the effect of exposure of medical students to formaldehyde at the Department of Anatomy, Niger Delta University, Nigeria.
  
  
  METHODS
  In a questionnaire-based study, 93 second-year medical students were surveyed at the Department of Human Anatomy, Niger Delta University, Nigeria. The average duration of exposure for each student in the dissection hall was 6 hr/wk. Participants with history of cough, respiratory or skin diseases were excluded from the study.
  
  
  RESULTS
  Out of 93 questionnaires distributed, 75 were completed and returned (response rate: 81%). Of 75 students, 58 (77%) were strongly affected by unpleasant smell of formaldehyde. It was followed by "runny or congested nose" and "redness of the eyes." "Skin-related diseases" was identified as the least ranked effect of formaldehyde.
  
  
  CONCLUSIONS
  Due to the numerous health challenges that formaldehyde causes to students in the gross anatomy dissection laboratories, it cannot be considered as a suitable chemical for embalmment of cadaver for dissection.
