Earthworms accumulate cadmium from quantum dot nanoparticles

Discovery: The use of quantum dots is expected to grow quickly in the coming years so understanding the danger of environmental exposure is becoming even more important. Further studies are ongoing to assess the stress earthworms experience in their metabolism when exposed to these low doses of quantum dots. This should provide a more sensitive measure of quantum dots harm to the environment. Learning: The quantum dot project serves as the basis for the PhD dissertation of IGERT trainee David Stewart, who has also engaged in multiple activities to support K-12 science education, including the development of teaching modules related to his research in partnership with science teachers in the Buffalo Public School system.
