Exposition des apprentis de la coiffure et de la boulangerie-pâtisserie à des facteurs de risque d'asthme

Abstract : Hairdressing and bakery are weIl known as occupations at risk of asthma. Exposure studies of apprentie es in hairdressing salons and bakeries are scarce, however. This work describes exposure levels and workplace air concentrations to airbome chemical products (ammonia, hydrogen peroxide, persulfates) used in hairdressing salons and personal exposure of flour dust used in bakery and pastry (PM2,5 et PM1O), and associated apprentices' exposure determinants. A questionnaire was completed by 586 apprentie es on their work activities and environment. 28 hairdressers and 34 bakery or pastry apprentices volunteered to undergo personal exposure and workplace concentrations measurements, during a cold and a hot season. Personal H202 and NH3 exposure values are greater than workplace concentrations, while the reverse holds for persulfates, with no seasonal variation. Exposure to flour dust (PM [subscript 10], PM[subcript 2,5]) is greater in winter than during the hot season. Results do not exceed the French limit values for NH3, H202, non specifie inhalable and respirable particulate matter. Average bakers' results were greater than the ACGIH recommendations, as were persulfates values. Few factors explained the high values of exposure; appropriate ventilation is showed as rarely implemented, however. This research suggests that reduction of exposure levels can be achieved, that would result in abatement of the risk of occupational asthma.
