摘要
Nowadays, nanotechnology has been widely used in many fields such as medicine, catalysis, food and agriculture. With the rapid growth of the production amounts of anthropogenic nanoparticles (NPs), they will inevitably enter the natural environment after use and disposal. As a result, their potential risks to the environment and human health have caused significant concerns. Tracing the sources and environmental transformation of NPs is the prerequisite for the accurate evaluation of toxicity effects and pollution control. The recent progress in the area of source tracing technologies for NPs, including multichemical fingerprinting technology, non-traditional stable isotope tracing technology, isotope labeling technology, and DNA labeling technology is outlined. Furthermore, the future development of tracing technologies of NPs is also prospected.
