Abstract
From 1975, in cold regions where there is a tendency for snow to accumulate, it became clear that road particulates, which occured as a result of the use of studded tires, brought about a new environmental problem. In particular, the notable vorsening of pollution in urban areas in Hokkaido, Miyagi, Nagano, etc. called for a resolution to the urban pollution. Although it is a slightly old story, the difficulties and details encountered by Miyagi Prefecture up until the establishment of the Law on the Prevention of the Generation of Particulates from Studded Tires and outline the movement of the SPM Measures are introduced.
