Much of Earth's nitrogen was locally sourced
I love this stuff !

Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. The study has implications for signs of potential habitability of exoplanets.

Where did Earth's nitrogen come from? Rice University scientists show one primordial source of the indispensable building block for life was close to home.

The isotopic signatures of nitrogen in iron meteorites reveal that Earth likely gathered its nitrogen not only from the region beyond Jupiter's orbit but also from the dust in the inner protoplanetary disk.

Nitrogen is a volatile element that, like carbon, hydrogen and oxygen, makes life on Earth possible. Knowing its source offers clues to not only how rocky planets formed in the inner part of our solar system but also the dynamics of far-flung protoplanetary disks.

The study by Rice graduate student and lead author Damanveer Grewal, Rice faculty member Rajdeep Dasgupta and geochemist Bernard Marty at the University of Lorraine, France, appears in Nature Astronomy.

Their work helps settle a prolonged debate over the origin of life-essential volatile elements in Earth and other rocky bodies in the solar system.

re: Much of Earth's nitrogen was locally sourced
It’s a bit odd to see nitrogen referred to as a volatile element. It makes up 78% of our atmosphere but, being unreactive, just sits there. It’s one of the six essential elements for life but I just wouldn’t call it volatile, like oxygen for example.

There’s another world in our solar system that has an atmosphere made up mostly of nitrogen, 95%. Titan has many similarities to an early earth. Dense atmosphere, lots of hydrocarbons and liquid seas where life may have formed. If it wasn’t one of the coldest bodies in the solar system, we might expect to find a unique abiogenesis there.

Maybe in this view, they meant easily evaporated, or rapidly changing ? Not sure either.
