Biological monitoring as a valid tool to assess occupational exposure to mixtures of 2,4-:2,6-toluene diisocyanate.

Background And Objectives: Despite its advantages over environmental monitoring, biological monitoring of exposure to 2,4-:2,6-toluene diisocyanate (TDI) mixtures is still underused. The present study was designed in order to evaluate the feasibility and reliability of biological monitoring in a factory producing polyurethane foam blocks.

Methods: Airborne TDI isomers were sampled by both static and personal pumps and determined by HPLC with fluorimetric detection.

[The new methodology to produce instruments for updating occupational physician proposed by Italian Society of Occupational Medicine and Industrial Hygiene (SIMLII)].

Starting from the experience of last five years, during which 24 guide liens about the most important aspects of Occupational Physician activity have been produced, the Italian Society of Occupational Medicine and Industrial Hygiene (SIMLII) delegated a specific working group for updating the methodology to be adopted for guide lines and other instruments for improving and standardizing the current activity in our professional field. SIMLII produced in the context of the specific Education and Accreditation Programme for occupational physicians prepared from 2002 25 guide lines or other informative instruments on the most important and controversial themes in which our discipline is involved. They were considered and treated to meet the need to improve and standardise activities and to modify the current approach of occupational physicians and aimed not only at improving the effectiveness of preventive actions but also at constantly adopting rigorous methodologies based where possible on evidence based or on consensus procedures.
