Endocrine Disruption

Endocrine Disruptor Screening Program Chemical Screening and Testing Progress

One of the goals of the Endocrine Disruptor Screening Program (EDSP) is to screen chemicals rapidly for bioactivity in several endocrine pathways. 

EPA has partial screening results for over 1800 chemicals that have been evaluated using high throughput assays and a computational model for the estrogen receptor pathway. In the future, EPA anticipates that additional alternative methods will be available for EDSP chemical screening, based on further advancements of high throughput assays and computational models for other endocrine pathways. These methods will allow EPA to screen more chemicals in less time, involve fewer animals, and cost less for everyone.
