Endocrine Disruption





On December 3, 2009 The Endocrine Disruption Prevention Act of 2009 was introduced in the US House of Representatives by Congressman Jim Moran, Northern Virginia and in the US Senate by Senator John Kerry, Massachusetts.

For decades, the National Institute of Environmental Health Sciences (NIEHS), through its intra- and extramural research programs, has been funding and conducting extensive research on exposure to chemicals for their full range of health effects, including specifically, effects on the endocrine system. 

This research contains a vast wealth of knowledge about the connection between low-level chemical exposure and human disorders, such as attention deficit hyperactivity disorder (ADHD), learning disabilities, asthma, juvenile cancer, juvenile and adult diabetes, autoimmune diseases, cryptorchidism, hypospadias, endometriosis, obesity, osteoporosis, testicular cancer, male dysgenesis syndrome, breast cancer, prostate cancer, Parkinson's disease and Alzheimer's dementia.

It is time to put this prevention-based research to use, with the goal of alleviating the burden that endocrine-related disorders are placing on families, our health care system and our national economy.

Simply put, the main purpose of the program proposed in the bill is to develop reliable and reproducible methods to identify chemicals that can disrupt the human endocrine system. These protocols will:

    • address the full range of possible health outcomes (including reproductive, behavioral, intellectual, metabolic, and endocrine disorders);
    • be sensitive enough to detect effects at exposure levels relevant to human exposure (and not rely on the assumption that a lower dose produces less effect);
    • consider the effects of exposure to multiple chemicals

The program will rely on a panel of scientific experts, free of conflict of interest, to design research efforts that will be conducted at the NIEHS and on academic campuses across the country. The panel will then evaluate the findings and determine their level of concern (taking into account routes and sources of exposure).


This information will be passed on to regulatory agencies (Environmental Protection Agency, Food and Drug Administration, Consumer Product Safety Commission, Occupational Safety and Health Administration, Department of Agriculture, etc.) who must propose a course of action for all chemicals with at least a minimal level of concern regarding the chemical’s ability to disrupt the human endocrine system.

These agencies need this research to back up regulatory action, and the NIEHS is the organization best equipped to provide it.
