  abstract = {{T}he accidental release of around 11,000 barrels of crude oil off the central {P}eruvian coast (11.92 degrees {S}, 77.18 degrees {W}) on {J}anuary 15, 2022, affected similar to 70 km of shoreline. {T}his study analyzes the spatiotemporal variation of metal concentrations in intertidal and subtidal zones from {O}ctober 2022 to {S}eptember 2023, and their effects on benthic foraminiferal communities. {M}etal concentrations were found to exceed background levels established by the {P}eruvian {E}nvironmental {I}nspection {A}gency. {A}lthough no temporal trends were detected, spatial differences were recorded. {I}ntertidal sites showed enhanced concentrations of {V}, {F}e, {C}r, and {M}n. {N}otably, the site closest to the spill ({V}entanilla {B}each; 11.87 degrees {S}), recorded the highest concentrations of {P}b, {C}u, {Z}n, and {A}s. {I}n the subtidal zone, concentrations increased with water depth and reduced hydrodynamic conditions. {T}he more sheltered site ({P}unta {M}ulatos; 11.76 degrees {S}) had higher {N}i, {P}b, {C}u, {C}d, {Z}n, and {A}s levels compared to the more dynamic site ({B}ahia {B}lanca; 11.83 degrees {S}). {F}urthermore, a contribution associated with natural rock leaching was detected. {T}hese findings suggest that the spill's influence on metal concentration is amplified by low hydrodynamics, low oxygen, high productivity and riverine inputs. {D}ominant benthic foraminiferal taxa, typical of oxygen-poor environments, were associated with enhanced {C}d, {C}u, {N}i, {C}r, and {P}b. {H}owever, isolating spill effects is challenging due to natural species tolerance and concurrent {E}l {N}ino conditions affecting oxygen levels and organic matter fluxes. {F}inally, 18 months after the spill, heavy metals persist in both environments, underscoring the need for long-term monitoring and mitigation.},
