The aim of the present study is to evaluate the personal exposure to formaldehyde in an autopsy room and in three pathological anatomy laboratories. Passive sampling for the whole workshift and HPLC analysis were performed. The final result showed a remarkable exposure of the workers enrolled. All the data obtained exceeded the NIOSH-TWA and several cases personal of exposure levels above the ACGIH-Ceiling value (0,37 mg/m3) were observed in the anatomy laboratory.
