Estimation de l’exposition aux retardateurs de flamme bromés dans un immeuble de bureaux : couplage de mesures dans le sang, dans l’air et dans les poussières des bureaux

Abstract : Polybromodiphenyl ethers are a family of 209 congeners widely used as brominated flame retardants in consumer products. They have the potential to be released into the environment and are suspected to be associated with endocrine disruption. PBDE are ubiquitous and persistent in environment, but the population exposure is not well known. The aim of this project was to compare measurements of PBDEs in dust and air from offices and in the blood of their occupants and to explain PBDE levels with declared exposures. The first step was to develop and optimize some sampling and analysis methods for blood, air and dust. Eleven congeners were studied. In the second step, about thirty volunteers and their own office were included in the study. PBDEs concentrations in blood ranged from 0,2-12,5 ng/g serum (mean is 2 ng/g serum), the major congener is BDE209. For most congeners, values are in the range of those found in European studies. The project does not reveal any significant relationship between concentrations in the air and the dust deposited in the investigated offices and blood levels of their occupants. Some relationships could be further investigated in a larger group using most specific tools and focusing on novel flame retardants.
