  Let $f:\CN \rightarrow \C $ be a polynomial, which is transversal (or
regular) at infinity. Let $\U=\CN\setminus f^{-1}(0)$ be the corresponding
affine hypersurface complement. By using the peripheral complex associated to
$f$, we give several estimates for the (infinite cyclic) Alexander polynomials
of $\U$ induced by $f$, and we describe the error terms for such estimates. The
obtained polynomial identities can be further refined by using the Reidemeister
torsion, generalizing a similar formula proved by Cogolludo and Florens in the
case of plane curves. We also show that the above-mentioned peripheral complex
underlies an algebraic mixed Hodge module. This fact allows us to construct
mixed Hodge structures on the Alexander modules of the boundary manifold of
$\U$.
