MINERAL COMPONENTS AND 3, 4-BENZPYRENE IN AIR POLLUTANTS OF TOKYO

Minerals and 3, 4-benzpyrene in particulate pollutants in winter air of Tokyo were studied by the methods developed by the authors. Minerals in air pollutants of Tokyo were quartz, feldspar, cristobalite, mica and kaolin minerals which were the mineral assemblage of Kanto loam constituting earth surface of Kanto plane. The highest con-centration of quartz in the air during this survey was 0. 034mg/m3, and mean concentra-tion of 3, 4-benzpyrene in Tokyo air was 15.1μg/1000m3. Obtained data were discussed in relation to "Tokyo-Yokohama asthma" and lung fibrosis.
