| Research Abstract |
The exposure of titanium dioxide(TiO_2) nanosized particle from TiO_2 photocatalytic materials was less than 1/50^th of permissible dose in NIOSH, suggesting that the risk of nano-particle exposure from the TiO_2 materials is very low level. The photocatalytic materials for soil and water purification were prepared respectively, and it was confirmed that polluted soil and agricultural wastewater were cleaned up by each system with the photocatalytic material in a level of practical use.
