abstract = {Contamination of plastic particles in environmental and
biological systems raises concerns regarding their potential
negative impacts. Human exposure to microplastics (MPs) and
nanoplastics (NPs) is increasing; however, some potential
adverse health effects might remain unclear, due to
analytical challenges in detecting trace concentrations. To
address this, we propose a workflow for NPs assessment in
biological samples combining three complimentary methods,
namely inductively coupled plasma mass spectrometry
(ICP-MS), X-ray fluorescence imaging (XFI), and imaging mass
cytometry (IMC) to detect palladium-doped NPs (Pd-NPs). This
approach was used to quantify the temporal distribution and
accumulation of Pd-NPs in mouse models under different
experimental conditions, dosages, and time frames. Acute
exposure showed a clear particle excretion from the
gastrointestinal tract into feces, while subchronic exposure
led to tissue accumulation. This workflow enhances our
ability to analyze and study NP uptake and biodistribution
mechanisms down to the nanoscale in complex biological
samples.},
