Since the 1990’s, many scientists have pointed out various chemicals might be disrupting the endocrine systems of people and animals. In 1996 the U.S. Environmental Protection Agency (EPA) formed scientific advisory committee to investigate such claims, and by 1998 the committee developed an Endocrine Distruptor Screening Program (EDSP). The program uses a uses a two tiered approach to screen pesticides, chemicals, and environmental contaminants for their potential effect on estrogen, androgen and thyroid hormone systems.
On June 30, 2015 the EPA released the first Teir 1 assessments of the EDSP. 52 “List 1” chemicals were subjected to the screening, and of the chemicals tested the EPA concluded that majority of these chemicals either didn’t exhibit bioactivity in the screening tests or otherwise posed no risk. 18 chemicals were identified as showing a varied amount of interaction with one or more of the three endocrine pathways examined. These 18 chemicals are recommended for further Tier 2 studies.
