The Endocrine Disruption Exchange
From 2003 to 2019, TEDX produced and shared scientific evidence of endocrine disruption with nonprofit organizations, government agencies, and the public. Although we are no longer operating, our website resources will remain available.


The TEDX List began with two reports listing endocrine disrupting chemicals: “Chemicals purported to be endocrine disrupters: A compilation of published lists” (IEH, 2005) and “Towards the establishment of a priority list of substances for further evaluation of their role in endocrine disruption: Final Report” (BKH Consulting Engineers, TNO Nutrition and Food Research. 2000). In 2011, TEDX researchers validated the citations in these lists and added more.

Evidence of endocrine disruption

Studies cited for evidence of endocrine disruption show direct effects on endocrine glands, their hormones and receptors, as well as hormone signaling cascades that affect physiological function. This includes function of the reproductive system, fetal development, the nervous system and behavior, the immune and metabolic systems, gene expression, and many other organs, glands and tissues.

The TEDX list contains an abbreviated selection of references because some chemicals have been studied extensively and have large literature bases. Therefore, the number of citations does not reflect the amount of research that has been done on an individual chemical, and should not be used to prioritize chemicals.

Use and Source InformatioN

Use and source information was obtained from the Hazardous Substances Data Bank (HSDB), Haz-Map, the Household Products Database, and PubChem. If the use/source information was not found in these databases, other documents were searched, including those from the US EPA Agency for Toxic Substances and Disease Registry (ATSDR), Chemical and Product Categories (CPCat) database, the Compendium of Pesticide Common Names, PAN pesticide database, manufacturer information, primary peer-reviewed literature, and patent information.

Use and Source Category Definitions

  • Antimicrobial: Chemicals that prevent the growth of and/or destroy microorganisms.

  • Biogenic compound: Naturally occurring or biologically derived chemicals such as phytoestrogens, flavonoids, monophenols, mycochemicals and phenolic acids.

  • Byproduct/Intermediate/Reactant: Chemicals used in the synthesis of other compounds and/or unwanted byproducts such as impurities and contaminants, including combustion byproducts.

  • Flame retardant: Chemicals used to prevent fires.

  • Food additives and contact material: Antioxidants, dyes, compounds used in food processing and as components in food packaging.

  • Household product ingredient: Chemicals found in items such as appliances, vehicles, building materials, electronics, crafts, textiles, furniture, and household cleaning products.

  • Industrial additive: Chemicals such as preservatives, antioxidants, and surfactants used in such things as glue, plastic, rubber, paint, and wood products.
