[Respiratory manifestations after exposure to sulfurous anhydride in wine-cellar workers: 6 case reports].
Sulfite treatment of wine [a process exploiting the biocidal and anti-oxidant properties of sulfur dioxide (SO2)] involves the use of liquified gas, aqueous solutions or bisulfites, i.e. the salts of sulfurous acid which slowly release SO2. This procedure can result in repeated exposures of operators to significant amounts of SO2. However, risks associated with the use of SO2 are greatly under-estimated by wine producers and wine-cellar workers. We report on 6 cases of respiratory symptoms attributable to SO2 identified during a survey of wine-cellars in the French Beaujolais district. Their pathogenesis is discussed after an overview of the occupational toxicology of SO2.
