Atmospheric dioxin, solidified in winter 1999.08.15

The research group at Setsunan University found that dioxin in the atmosphere was a gaseous state in the summer, and in winter, it adhered to the airborne particles and made it solid. In addition, the atmospheric dioxin concentrations combined with gaseous conditions and particles were generally found to be higher in winter than in summer. The fact that the state of dioxins in the atmosphere is understood helps humans understand the process of capturing dioxins through breathing.
