Abstract: Suppose $ F$ is a closed, genus $ g$ surface which is standardly embedded in $ {S^3}$. Let $ \gamma $ denote a primitive element in $ {H_1}(F)$ which satisfies $ {\theta _F}(\gamma ,\gamma ) = 0$ where $ {\theta _F}$ is the Seifert pairing on $ F$. We obtain a number theoretic condition which is equivalent to $ \gamma $ being realizable by a curve (in $ F$) which is unknotted in $ {S^3}$. Various related observations are included.
