In this project, an Internet databank of the environmental nanotechnology has been established. Fields of air pollution control, waste water treatment, soil and ground water pollution treatment, environmental impaction and health risk of nanotechnology, and sensing technology are classified in this databank. There are introductions of 40 research institutes, news, related journals and 70 research papers, and introductions of 110 international and domestic researchers in the databank.
In 2002, USEPA invited more than 100 scientists and engineers to conferences of environmental nanotechnology and related issues and many important conclusions have been reached. Taiwan EPA adapted these important conclusions and complied into 36 topics that are related to environmental nanotechnology. 32 topics have been collected and written for the references of Taiwan EPA and publics. A priority list of possible environmental nanotechnology projects was suggested by an assessment of Taiwan’s research and development capacities.
Differential analyses of bulk and nano materials are used to construct MSDS for some nanomaterials, such as CNT, CB, C60, TiO2, Teflon, Pt, Ir, polystyrene, MnO2, and Ag nanopowder. Moreover, exposure evaluations of two pilot nanopowder processes have been evaluated on-site to assess nanoparticle emissions. The results showed the stages of product collections and machine maintenances released high concentrations of nanopowder into the work environment. According to these findings, protective guidelines and operational protocols for the operators of nanopowder processes were drafted.
A forum and international symposium were held in this year. The current developments of environmental nanotechnology were elaborated and discussed as well as the academic and industrial collaborations between domestic and international professionals were achieved and established during these conferences. The suggestions of these conferences showed researchers should investigate the potential risk of nanotechnology on environmen
