With the rapid development and wide application of nanotechnology, the introduction of manufactured nanomaterials into both solid and liquid wastes (and to the environment) is inevitable through production, use, and disposal. It has been reported in 2008 that nano-TiO2 is leached out of house facades into receiving surface waters. Currently, there are over 800 products on the market containing nanomaterials such as lotions, sunscreens, paints, and socks. This research will determine the environmental behavior and process of several types of manufactured nanomaterials. The results of this study are expected to help us understand how these manufactured nanomaterials interact with natural and synthetic molecules, and their fate, mobility, exposure and bioavailability in the environment.
