Recent downward revision of solar heavy-element abundances using a three-dimensional atmospheric model has introduced serious discrepancies between standard solar models and helioseismic inferences about solar structure. In this paper we investigate the possibility of determining the heavy-element abundances using helioseismic inversion techniques with the hope of providing an independent estimate. We use the adiabatic index Γ_1 = (∂ ln P/∂ ln ρ)_s as a probe to examine the effects of the total heavy-element abundance, as well as the effects due to the abundance of individual elements. Our inversion results show that the new, lower, abundance increases the discrepancy between the Sun and the solar models.
