BackgroundThe exposure of healthcare workers to anticancer drugs such as cyclophosphamide (CPA) is a serious health concern. Anticancer drug pollution may spread outside biological safety cabinets even when a closed system is used. The inhalation of vaporized anticancer drugs is thought to be the primary route of exposure. Therefore, it is important that healthcare workers wear masks to prevent inhalation of anticancer drugs. However, the permeability of medical masks to vaporized anticancer drugs has not been examined. Furthermore, the performance differences between masks including activated carbon with chemical adsorptivity and non-activated carbon masks are uncertain. We investigated activated carbon mask permeability to vaporized CPA, and assessed whether inhibition of vaporized CPA permeability was attributable to the masks’ adsorption abilities.
