Overview

Formaldehyde is notably used as a tissue fixator in pathological anatomy. Despite its toxicity, it continues to be widely used because it is currently not substitutable. Some plants have shown their ability to absorb formaldehyde. The investigators would like to show if the installation of plants in the Anatomy and Cytology Department of the Amiens University Hospital reduces the exposure to formaldehyde of the staff of this department. After carrying out atmospheric and biological measurements the investigators will install 15 plants in both rooms where the staff is most exposed to formaldehyde : the macroscopy room and the reception room. The atmospheric and biological measurements will be redone after two months.
