Hi. Hope everything going fine. 

I have assessed the dataset from ecoinvent 3.6 Liquefied petroleum gas RoW market for, APOS, U with Recipe midpoint H 2016 and I get a different result than with Simapro. I´ve been looking the results from Simapro and I find that the Recipe method dont include the impacts from nitrogen as shown in the image below

I export the results from OpenLCA and exclude the following emissions

And I assessed the impacts shown in the attached file using the impact factors from the récipe method in OpenLCA. The results from Simapro are 3.47 E-6 and those are the results shown in the following table. I would really appreciate if you could tell me the reason of the differences.

I would like to know if I should exclude Nitrogen atmospheric emissiones from my assessment.
