Effects of ionic composition of freshwater on silver nanoparticle sedimentation rates
Research Mentor(s)
Sofield, Ruth M.
Description
My project investigates how rates of AgNP sedimentation respond to the presence of individual freshwater ions and their combined effects on the mortality rates of Daphnia magna. Claire Walli is researching how the toxicity of AgNPs to Daphnia magna changes in the presence of specific freshwater ions. Working with Claire Walli, I have gathered data on the sedimentation rates and toxicity of AgNPs to D. magna in different freshwater media. Ultimately, these data will be used to generate an EC50 that will inform a Time--To-Death toxicity test. This test investigates how the rates of AgNP sedimentation out of the water column relate to the rates of D. magna mortality.
