Contaminants produced by human activities are found all over the globe due to atmospheric and oceanographic movements. As a result, humans, wildlife and our environment are exposed to multiple contaminants worldwide. The exposure effects of these contaminant cocktails on human and wildlife health is of increasing concern within a one health perspective. Among these contaminants, endocrine disrupting chemicals (EDCs) may cause a large array of adverse effects. Birds are globally considered model bioindicators of environmental health. EDCs affect their behavior, fecundity, growth, survival, disease resistance, sex determination, other components of life history. Among birds, ducks are of particular interest to examine EDCs exposure and its effects because ducks are widespread, well monitored, their ecology and physiology are well known. They also use surface water with different levels of contamination like marine waters, and agricultural and urban wetlands. The DISRUPT project (sites.utu.fi/disrupt/) investigates EDCs exposure and their biological effects in breeding female ducks, and their eggs and ducklings. We have established that Finnish breeding female ducks are contaminated by a mixture of EDCs including per- and polyfluoroalkyl substances (PFASs), some of which are of emerging concern, including phthalates, benzophenones, and lead (Pb). We have also shown a maternal transfer of EDCs from hens to their eggs. Our results have implications observed high hatching failure and avian influenza outbreaks.
