Health Risk from Exposure to Suspended Particulate Matter after the East Japan Great Earthquake - Focusing on Risk Assessment of Asbestos

Abstract

For complete revival of the East Japan great earthquake, withdrawal of waste and sludge, disassemble of collapse buildings, etc. are performed over a long period of time. In these cases, many particulate matters included asbestos are generated, and will induce lung cancer or mesothelioma in tens of years. Since the health risk following exposure to the present environmental concentration of asbestos is about 10^-5, we should control the scattering of asbestos into environment and prevent the inhalation by wearing an anti-dust mask (national assay disposable mask DS2, N95) .
