The manufacture and use of nanoparticles is rapidly expanding in Missouri and nationally. Little is known regarding the environmental, toxicological and human health effects of these emerging contaminants. Furthermore, little study has been conducted on developing and optimizing cost-effective technologies to control the release of nanoparticles from treatment processes and commercial faculties. ERC researchers have tremendous capability for developing understanding and technologies in the area of nanoparticle contaminants and have begun collaborative research thrusts into this important emerging area.

 Current Projects in the ERC:  

• The Ma/Huang groups are conducting research on the cytotoxicity of nanomaterials. Nano-technology has grown significantly in the past several years and will revolutionize the current technology in the near future. However, its environmental impact has not been well investigated, including that in Missouri. In our study, we are investigating the possible cytotoxicity of metal oxides (such as CeO2, Al2O3, TiO2, Fe2O3, ZnO) and non-metal oxide (such SiO2) at different sizes. Preliminary data have demonstrated that these nanomaterials are cytotoxic at the nano-diameter level. This study can be used by federal agencies to make regulatory policies for nanomaterial manufacturers. Three manuscripts that were produced for this study are either under review or in the submission process).
