Growing evidence in support of a connection between Active Galactic Nuclei
(AGN) activity and the Ram-Pressure Stripping (RPS) phenomenon has been found
both observationally and theoretically in the past decades. In this work, we
further explore the impact of RPS on the AGN activity by estimating the
gas-phase metallicity of nuclear regions and the mass-metallicity relation of
galaxies at zβ€ 0.07 and with stellar masses logMββ/Mβββ₯9.0, either experiencing RPS or not. To measure oxygen
abundances, we exploit Integral Field Spectroscopy data from the GASP and MaNGA
surveys, photoionization models generated with the code CLOUDY and the code
Nebulabayes to compare models and observations. In particular, we build CLOUDY
models to reproduce line ratios induced by photoionization from stars, AGN, or
a contribution of both. We find that the distributions of metallicity and [O
III]Ξ»5007 luminosity of galaxies undergoing RPS are similar to the ones
of undisturbed galaxies. Independently of the RPS, we do not find a correlation
between stellar mass and AGN metallicity in the mass range logMββ/Mβββ₯10.4, while for the star-forming galaxies we observe the
well-known mass-metallicity relation (MZR) between 9.0β€logΒ Mββ/Mβββ€10.8 with a scatter mainly driven by the star-formation
rate (SFR) and a plateau around logMββ/MβββΌ10.5. The
gas-phase metallicity in the nuclei of AGN hosts is enhanced with respect to
those of SF galaxies by a factor of βΌ 0.05 dex regardless of the RPS
