  Hot ionized gas is observed in the local vicinity of our galaxy through
spectral absorption features. The most common hypothesis is that this gas forms
a halo surrounding our Milky-Way (MW), in collisional ionization equilibrium.
In this paper we investigate the elemental abundance of this hot and ionized
local gas. We use a 2.4 Ms stacked X-ray spectrum of the bright blazar 3C 273
and probe the local absorption features. Using ion-by-ion fitting of the X-ray
absorption lines we derive the column density of each ionization species. Based
on the column densities we reconstruct the Absorption measure distribution
(AMD), namely the hydrogenic column density as a function of temperature. We
report the elemental abundances of C, N, Ne, and Fe relative to solar O.
Previous measurements of local X-ray emission lines in conjunction with the
present column densities indicate a scale height of $1-80$ kpc and hydrogen
number density of $10^{-4}-10^{-3}$cm$^{-3}$ for the hot ionized gas.
Additionally, we detect He-like O lines from the quasar broad line region with
velocities of 6400$\pm$1500 km s$^{-1}$
