The recent downward revision of solar photospheric abundances of oxygen and other abundant heavy elements has caused a serious discrepancy between the standard solar model and the seismically determined solar structure. In this work we attempt to determine the heavy element abundance in the solar convection zone, using the dimensionless sound-speed derivative. This should provide an independent check of the spectroscopically determined abundances.
