Formaldehyde (FA) is widely used in medical laboratories and has been classified by International Agency for Research on Cancer (IARC) as a group 1 carcinogen. The aim of this study was to assess the health risk of inhalation exposure to formaldehyde among staff in medical laboratories such as those in pathology, anatomy, forensics, and parasitology. A total of 33 staff members were included in the study. Data on FA exposure were collected by air monitoring in the laboratory areas by using Gasmet DX-4030, and the human health risk was assessed by the guidelines of the US. Environmental Protection Agency (2009). The study showed that 21.21% of the personnel exposed to FA had health risks with non-carcinogenic effects (hazard quotient range = 0.02 to 11.4), and with regard to cancer risk, the highest risk was found to be in pathology technicians (6.51x10-4), followed by investigative mortuary personnel, residents (sixth-year medical students), embalming mortuary personnel, and instructors or those working in forensic laboratories (3.25x10-4, 6.07x10-5, 3.39x10-5, and 1.27x 10-5, respectively). Those staff had a higher than acceptable risk of cancer (>10-6). It is recommended that workers’ FA exposure should be reduced by working with formalin in a fume hood, reducing exposure h and using respiratory cartridges. |
