Reproductive failure and endocrine disruption by organohalogens in fish-eating birds

Effects of organohalogens in fish-eating birds in the field have been monitored largely by studying reproductive outcome in contaminated populations or, at the individual level, by studying the sexual behaviour, egg production, or embryonal and postnatal development and survival. Endocrine disruptio...

Description
Summary:Effects of organohalogens in fish-eating birds in the field have been monitored largely by studying reproductive outcome in contaminated populations or, at the individual level, by studying the sexual behaviour, egg production, or embryonal and postnatal development and survival. Endocrine disruption has been suggested as a mechanism, but proven cause–effect relationships between specific compounds and endocrine disruption with subsequent reduced reproductive outcome in fish-eating birds are scarce. The effects of organochlorines on hormone metabolism and circulating steroid levels are reviewed and discussed in relation to observed reproductive failures in the field.
