Healthy Environment and Endocrine Disruptor Strategies
HEEDS is a non-profit coalition of scientists dedicated to improving communication, coordination and collaboration in the field of endocrine disrupting chemicals (EDCs). HEEDS is developed by scientists for scientists. There are no membership fees. HEEDS works to move EDC science forward, increase collaborations across scientific disciplines, communicate results and improve policy and regulations.
