NP characterization by TEM and EDX in substantia nigrae. Different sizes and shapes of NPs are seen through the SNpc cells and the neuropil. (A) Three HgNPs are identified, (B) The predominant NPs are Fe and Hg in this sample. (C) In a close-up of a finger-like macrophage extension towards the neuropil (from square in (B)), we documented the accumulation of predominantly FeNPs. (D) Hg is the main element detected in another SNpc sample from a teen. Ni reflect the TEM support grid.
