In this project, the constructed Internet databank on environmental application has collected the international environmental nanotechnology information including U.S.A., Canada, U.K., French, Japan, Taiwan, and Mainland China. It contained research fields of air pollution control, waste water treatment, soil and ground water pollution treatment, environmental impact and health risk of nanotechnology, and sensing technology. Up to this present, the databank has contained 38 records of research organizations, 35 records of related journal and news, 85 records of related literatures, 150 records of researchers’ background. To promote the communication and development of environmental nanotechnology, EPA in Taiwan had hold 6 professional forums. The 60 invited speakers have presented topics related to environmental impact and health effect. These presentations are well receiving by many researches of institutes and EPA. The proceeding of 1st to 6th forum about nanotechnology on environmental protection has also been post on the web site, and people can download these files from the EPA Internet (web site: http://www.epa.gov.tw/cooperation/奈米技術/index.htm).
The local environmental assessment model and assessment index were constructed. The assessment results have showed that both nanoscale photocatalyst (TiO2) and carbon nanotube pose more potential environmental risk at manufacturing stage than other life cycle stage. In studies of environmental nanotechnology development, we have developed a synthesis approach for nanoparticle cross-linking oxide gel monoliths or film/polyester PET fiber composites. In addition, we found nano-iron particles, coated with few palladium, could decompose CHCl3 to CH4 in contaminated water.
