Quantification des émanations de substances dans l'air ambiant a partir des bois traités
H Sageot, M Lamour
Pesticides on wood for the purpose of its protection may evaporate. Eventual toxicity of such emanations justifies risk assessment procedures for indoor air in building. This document describes bench scale tests based on the technique of chambers developped by CTBA/BIOTEC to determine the amount of pesticides and associated substances released to the ambient air. Results obtained with various pesticides are reported. The part played by physico-chemical parameters including formulation is also described. Conclusions are that relevance of risk assessment procedures must pay atention to formulation, wood and in service conditions and that specific models might be necessary.
