  • Addressing the Risks of Nanoscale Polymers: Exposure, Behavior, and Toxicity

    Creator:
    Stine, Jared
    Abstract:
    Nanoscale polymers (including nanoplastics) are widely present through commerce and make their way into the environment. As the improper disposal of plastic waste leads to continued accumulation and degradation of plastic pollution, the presence of plastic particles less than 1 micron (μm) in size (nanoplastics) will increase. Heightened concern over...

  • A Nano-sized Dose of Toxicology: Elucidating the Disconnect Between Nanomaterial Dosimetry and Biological Effects

    Creator:
    Slattery, Matthew R.
    Abstract:
    Nanotechnologies continue to permeate a multitude of industries, with diverse applications ranging from pesticides to fuel additives. The unusual behavior of nanomaterials that drives their innovation also complicates the job of toxicologists tasked with assessing their potential environmental and public health impacts. This dissertation investigates the underlying reasons for uncertainty...

  • Addressing Persistent Challenges in Nanotoxicology Exposures : Techniques for in situ Characterization

    Creator:
    Crandon, Lauren E.
    Abstract:
    Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...

  • Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

    Creator:
    Wu, Fan
    Abstract:
    Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...
