- To have the same as Marcello's paper

Abstract:
- Line 46, 50: "Ecological". Meaning (from Cambridge): "relating to ecology or the environment". Perhaps ecological-friendly or eco-friendly is better?

Chapter 1
- Line 63,64: I always understood that laboratories are not implicitly included in the eu regulation, but they are not explicitly excluded. Can you cite the source?

- Line 66: The citation style of CERN environment report is different from the other citations

- Line 78: Alternatives for the C2H2F4 -> Alternatives to C2H2F4

- Line 82, 83 something odd in the period:
Replace "... in two allotropic forms:" with "...in two allotropic forms,"

- Line 200: ALTAS -> ATLAS

General: Sometimes I see "EPDT" and some other times "EP-DT": I would say to chose one for consistency

- Line 452: mC/cm2

- Line 458: the absorbed currents at source on.
It seems that the absorbed currents at source off is less stable starting from 40 mC/cm2


- Line 506: R134a was never mentioned before. Perhaps C2H2F4 it's better

- Line 540: "these effect" -> "these effects"
