Particulate matter ecoinvent/simapro

[ccomb]

Trying to import a simapro-exported EF 3.1 in brightway along with an Ecoinvent 3.9.1, I discovered that the Particulate Matter impact category is missing some characterization factors.

In the ecoinvent ecospold2 I can find: <name xml:lang="en">Particulate Matter, &lt; 2.5 um</name>
In the simapro-exported EF3.1 I found: Air;(unspecified);Particulates, < 0.2 um;;0,000238497;kg;B8E15A53-B622-401C-BEC8-FF847B7EF5A5

There is nothing in brightway to convert Particulates to Particulate Matter.

My first idea is to add this in the simapro-biosphere.json:

  [
    "air",
    "Particulates, < 2.5 um",
    "Particulate Matter, < 2.5 um"
  ],
  [
    "air",
    "Particulates, > 2.5 um and < 10um",
    "Particulate Matter, > 2.5 um and < 10um"
  ],
  [
    "air",
    "Particulates, > 10 um",
    "Particulate Matter, > 10 um"
  ],

It looks like there is a lot of similar cases.
I found this other example ["air", "Barium (II)", "Barium II"],.

@cmutel Is there a mapping table between the simapro biosphere and the ecoinvent 3.9 biosphere ?
