Changes to ecoinvent 3.10.1
Part of What was changed in each source. What is still open about ecoinvent is on the issue tracker under the label ecoinvent.
ecoinvent 3.10.1 is extracted and curated — 4,362 rows, corrected by
ecoinvent-3.10.1-manual-fixes.json and the ecoinvent-match-overrides.json
shared by every ecoinvent release — and it can be merged, but it is not part
of the standard build: the 2026-08-29 build of 54b0f9d merged
ecoinvent 3.12 and ecoinvent 3.8
only. An ecoinvent uuid is the same in every release, so what those two pages
say about a row is what the merge would do with 3.10.1's copy of it.
One name, two substances
Which rows of a name land on which substance is measured on a build, and this release is not in one. For the rows it shares with the merged releases, read the same section on the 3.8 and 3.12 pages.
An ionic charge was added or corrected
Whether a row's published name carries a charge its source name did not is
measured on a build, and this release is not in one. What can be said is how
the release names dissolved metals, and where 3.12 has since changed its
mind about a row — because the rule for a release with no correspondence
table is that ecoinvent's newest name for a uuid is the one that counts, and
that rule is written down in ecoinvent-canonical-identities.json.
By 3.10.1 ecoinvent had finished renaming its dissolved metals: the release
names 25 metal ions with a Roman numeral — Aluminium III, Chromium VI,
Sodium I, Strontium II — and six with the word ion and no charge —
Antimony ion, Arsenic ion, Copper ion, Iron ion, Tin ion,
Titanium ion. Publishing Chromium VI as Chromium(6+) is notation only
and is not a change. Every bare element name in the release is a
natural resource / in ground row carrying the element's own registry
number; none carries an ion's.
Two rows are stated differently in 3.12, and 3.12's statement is the one the merge would use:
| 3.10.1 name and number | Rows | 3.12 name and number for the same uuids | What the merge would publish |
|---|---|---|---|
Calcium II, 7440-70-2 (calcium metal's number, under the ion's name) |
8 emission rows to air and soil | Calcium II, 14127-61-8 (the ion's number) |
Calcium(2+) — the charge is in the name here; what 3.12 corrects is the CAS number beside it. The five Calcium II rows to water already carry 14127-61-8. |
Iodine, no registry number |
1 (natural resource / in water) |
Iodine, 7553-56-2 |
Iodine — a CAS number supplied, no charge involved |
Rows merged into one flow
Which rows of this release land together on one consensus flow is measured on a build, and this release is not in one. The 3.8 and 3.12 pages list the merges for the rows those releases share with this one.
Registry numbers corrected
Each of these is written down in ecoinvent-3.10.1-manual-fixes.json with
the evidence in full; the reasons below are condensed. The stale
registrations 3.8 and 3.9.1 carry on their fenpropimorph, borax, diatomite,
fluorspar, baddeleyite and coal-mine gas rows are already corrected in this
release by ecoinvent itself, so they do not appear here.
| ecoinvent name | Rows in 3.10.1 | Number shipped | What it designates | Corrected to | What that designates | Why |
|---|---|---|---|---|---|---|
Molybdenum VI |
13 (one per emission context) | 7439-98-7 | Molybdenum, the metal | 16065-87-5 | The hexavalent molybdenum ion, Mo⁶⁺ | The rows name the ion and write the formula Mo+6; release 3.9.1 registered the same thirteen uuids with the ion's number, and 3.10.1 is where the number changed to the metal's while the name stayed. With the metal's number the rows were published as Molybdenum, the element, on the 2026-08-29 build (#828). |
Strontium II |
13 (one per emission context) | 7440-24-6 | Strontium, the metal | 22537-39-9 | The divalent strontium ion, Sr²⁺ | The rows name the ion, as 3.8 and 3.12 do, and every other Roman-numeral metal carries its ion's number; with the metal's number they were published as the element (#934) |
Caesium I |
5 (one per water context) | 7440-46-2 | Caesium, the metal | 18459-37-5 | The monovalent caesium ion, Cs⁺ | The same slip on the caesium ion (#934) |
Uranium-238 |
9 (543421e8-f0b3-45a2-b0ed-03489e878138 and eight others, in kBq) |
7440-61-1 | Uranium, the element, by mass | 24678-82-8 | The nuclide U-238 | The rows measure the activity of one nuclide; every list that ships the row (3.8 through 3.12, EF 3.1) carries the element's number and is corrected the same way, so the lists agree about what the nuclide's number is (#200). |
Water, salt, sole |
1 (79238018-8ec1-4615-9469-2b0df95a43c3, natural resource / in water, m³) |
7732-18-5 | The water molecule | removed | — | Sole is German for brine, a saturated salt solution; a mixture does not carry the registry number of one of its constituents. EF 3.1's copy of the flow is corrected the same way. The synonym oxidane, the IUPAC name of water, is removed for the same reason. |
Nitrogen, organic bound |
5 (water: ground-, ground- long-term, ocean, surface water, unspecified) | 7727-37-9 | Dinitrogen, N₂, the gas | removed | — | Organically bound nitrogen is a measurement over many compounds rather than one compound, and with the gas's number left in place the rows fuse with the gas (#355). The synonyms dinitrogen and molecular nitrogen, which ecoinvent copies onto these rows from its Nitrogen rows, are removed for the same reason. |
Stibnite |
1 (3e0034cd-21d6-4582-9fbf-09c26edd05df, natural resource / in ground, kg) |
1345-04-6 | Antimony trisulfide, the manufactured chemical | 1317-86-8 | Stibnite, the mineral | The row is ore taken out of the ground; IARC separates the two registrations as compound and mineral, and BAFU independently registers its stibnite 1317-86-8. EF 3.1's thirteen antimony trisulfide rows are emissions and keep the compound's number (#604). |
Granite |
1 (a4375a18-172c-4f82-90b7-bca972f75548, natural resource / in ground, kg) |
219714-96-2 | Penoxsulam, a rice herbicide sold under the trade name Granite | removed | — | The row is the rock; the herbicide's number reached it through the trade name, and ecoinvent removed it in 3.11. Left in place, the merged row was relabelled Penoxsulam (#670). |
Mefentrifluconazole |
1 (a1f19e68-e0ca-4d2b-a159-38e9036542f3, soil / agricultural, kg) |
none | — | 1417782-03-6 | Mefentrifluconazole, BASF's triazole fungicide (Revysol) | 3.10.1 introduces the row with no identifier of any kind, and the trivial name cannot be parsed into a structure, so nothing could place it; PubChem's record for the substance (CID 71230671) lists the name among its synonyms and this number as its registry number (#202). |
Beta-cyfluthrin |
5 (soil, air and water rows, kg) | 68359-37-5 | Cyfluthrin, the commercial eight-isomer mixture | 1820573-27-0 | Beta-cyfluthrin, the product enriched in the two most insecticidally active diastereoisomeric pairs | PPDB registers the two products separately (records 74 and 192). ecoinvent's own transition table retired the name Cyfluthrin for these uuids in favour of Beta-cyfluthrin, while EF 3.1 ships plain cyfluthrin under the shared number, so the beta rows fused with the plain substance; the shared EC number 269-855-7 stays. Every release ships the rows and takes the same correction (#854). |
Other corrections
These change a name, a synonym or a unit rather than a CAS number.
| ecoinvent name | Rows in 3.10.1 | Change | Why |
|---|---|---|---|
Silver-110 |
9, in kBq | Renamed Silver-110m; Silver-110 kept as a searchable alternative name |
Silver-110 is a 24.56-second ground state; the species a reactor-effluent inventory reports is the isomer Ag-110m, at 249.863 days, which is what EF 3.1's characterisation factors describe (#219). The number 14391-76-5 stays: it indexes the mass number and there is no nuclide-specific number for the isomer. |
Ioxynil methyl ester, 2436-73-9 |
1 (soil / agricultural) |
Renamed MCPA-methyl, and the old name is not kept |
2436-73-9 contains no iodine: it is methyl 2-(4-chloro-2-methylphenoxy)acetate, the methyl ester of MCPA. ecoinvent's three other ioxynil flows carry correct numbers, so the name slipped and the CAS number is kept (#326). |
Zirconia, as baddeleyite, 12036-23-6 |
1 (e07b4402-abe3-4346-8c42-051c5983bd1e) |
Renamed Baddeleyite |
Zirconia is zirconium dioxide, and the row is the mineral being mined; the mineral's own name is shorter and more accurate (#596). |
Peat |
1 (c5035ce2-5ee5-431f-a287-4b25da42be74, natural resource / biotic, kg) |
Renamed Peat, horticulture; Peat kept as an alternative name |
EF 3.1 has two peats: fuel peat in megajoules, and this one, dug for growing media and counted by mass. Under the bare name the kilogram row reached the megajoule flow and its own factor stopped being published (#450). |
Gypsum, 13397-24-5 |
1 (11a2a7b1-ab2f-47b8-9e29-6f33d5207fa6) |
Synonyms sulfate and dihydrate removed |
They are the words of the real synonym Calcium sulfate dihydrate split apart, and sulfate names a substance the list publishes, which gypsum reached by it (#597). |
Occupation, arable, conservation tillage (obsolete), … conventional tillage (obsolete), … reduced tillage (obsolete) |
3 (fdb1b2d0-f537-401e-b845-1d93da512174, e489cce4-a80f-417d-9ae6-9fc14cc7dd49, 81e07a67-28e0-4392-a553-d86e54a9b8a9) |
Unit m² → m²·a, factor 1.0 | Every other land-occupation row in ecoinvent and in EF 3.1 is an area held for a time; ecoinvent's own correspondence tables map these three at 1.0 with the comment assumed conversion based on land use through an entire year (#565). |
