Correction: Comodi et al. Multi-Scale Minero-Chemical Analysis of Biomass Ashes: A Key to Evaluating Their Dangers vs. Benefits. Sustainability 2021, 13, 6052

The authors would like to make the following corrections to the published paper [1]. The changes are as follows:

• (1) Replacing the heading of “Section 2.2.5.” on page 3:
  • “EMPA Analysis”
• with
  • “EMPA and LA-ICP-MS Analyses”
• (2) The authors wish to add an explanation along with a reference in “Section 2.2.5.” on page 4.
  • Replacing the original version:
    The glass pellets obtained after the quenching were embedded with epoxy resin; the mounts were cut, ground, and highly polished down to a 1 µm grade diamond polishing paste.

  • The glass pellets obtained after the quenching were embedded with epoxy resin; the mounts were cut, ground, and highly polished down to a 1 µm grade diamond polishing paste. Minor and trace elements were analysed at the Department of Physics and Geology (Perugia University) by LA-ICP-MS using the analytical protocol reported in Ref. [25].

• (3) Replacing the caption of Table 4 on page 11:
• Table 4. Minor elements (ppm), measured with EMPA, in the four samples (2, 3, 4, and 5).
• with
• Table 4. Minor elements (ppm) measured with LA-ICP-MS in the four samples (2, 3, 4, and 5).
