Monitoring Titanium Dioxide Engineered Particles In Rural And Urban Surface Waters, Md Mahmudun Nabi

Theses and Dissertations

Quantifying and characterizing engineered particles in environmental systems is key for assessing their risk but remains challenging and requires the distinction between natural and engineered particles. The Ph.D. dissertation research described in this thesis contributes to the current attempts to improve environmental nanoparticle analysis and better understand nanoparticle behavior in natural systems, with the focus being on natural streams, and the application of single particle inductively coupled plasma-time of flight-mass spectrometry (SP-ICP-TOF-MS) for distinguishing and tracing the origins of environmental nanoparticles. The objective of this dissertation is to characterize and quantify the concentrations of titanium dioxide engineered particles in urban …
