George Bittner, a neurobiology professor, conducted research and co-authored the paper in the NIH journal, Environmental Health Perspectives. This proved the presence of synthetic estrogen activity under microwave heat and dishwasher steam. The effects were infertility, asthma, genital deformity and heart-related conditions.
