The endocrine disruptor group research programme focuses on endocrine disrupting environmental and food based toxins resulting from modern day industrial, agricultural or natural sources and assessing the effects that these contaminants may have on human health. The Connolly team primarily utilise in vitro bioassays for the screening of endocrine disruptors in food and feed and assessing their adverse biological effects in mammalian health. This work also covers horizon scanning for emerging endocrine disruptors, assessing their mode of action and mixture effects. The overall aim of this research is to identify risk and provide information to aid exposure prevention.
