Abstract Recent work practices in the conservation and restoration involve the use of cyclododecane (CDD) to protect fragile artifacts during their handling or transportation. Little is known about its toxicity, and no previous exposure has been reported. A short field investigation was conducted to characterize the exposure conditions to both CDD vapours and aerosols. Measurements were conducted in the laboratory of conservation and restoration of the archaeological service in Berne, Switzerland. Three indoor and four outdoor typical work situations, either during brush or spray gun applications, were investigated. Measurements were performed on charcoal adsorbent tube and analyzed by a gas chromatograph equipped with a flame ionization detector. Indoor exposures were of 0.75-15.5 mg/m3, while outdoor exposures were 19.5-53.9 mg/m3. Exposures appear to be extremely localized due to both physicochemical properties and application methods of the CDD. Vapour exposure increases dramatically with the confinement of the workplace. Preventive measures should be undertaken to limit as much as possible these exposures. Field work in confined areas (ditches, underground) is of particular concern. CDD-coated artifacts or materials should be stored in ventilated areas to avoid delayed exposures.
