Since the new classification of formaldehyde as a Type 1B Carcinogentook place, several scientific papers have been published studying the exposure of medical and nursing staff to its toxic fumes in relation to the health effects of this exposure. A notable paper is the one concerning the exposure of the nursing staff at the "Città della Salute e della Scienza" hospital in Turin, Italy.

Also in Portugal, research was conducted and subsequently published, which examines the exposure to formaldehyde of two different groups of workers: those employed in the industry and those working in the country's pathological laboratories. The study concludes that the long-term daily exposure of workers to formaldehyde vapors increases the risk of health damage and recommends the adoption of protective measures.
