Congenital Diseases and the Environment

Abstract

It is the policy of AREHNA, EU-SANCO project, to encourage the full spectrum of opinions to be represented at its meetings. Therefore it should not be assumed that the publication of a paper in this volume implies that the Editorial Board is fully in agreement with the contents, though we ensure that contributions are factually correct. Where, in our opinion, there is scope for ambiguity we have added notes to the text, where appropriate.
