Strategy for Evaluating Evidence of Low-Dose Toxicity from Endocrine Active Chemicals
ثبت نشده
چکیده
Identifying toxic chemicals is important for safeguarding human health. This report outlines a strategy to improve regulators’ ability to evaluate concerns that certain chemicals might cause hormone-related health effects at low doses. Two evaluation approaches of the strategy—systematic review and evidence integration—are demonstrated with data from animals and humans on two classes of endocrine active chemicals. These examples illustrate cases where the evidence supports low-dose effects in people.

Summary of the National Toxicology Program's report of the endocrine disruptors low-dose peer review.
At the request of the U.S. Environmental Protection Agency (U.S. EPA), the National Toxicology Program organized an independent and open peer review to evaluate the scientific evidence on low-dose effects and nonmonotonic dose-response relationships for endocrine-disrupting chemicals in mammalian species. For this peer review, "low-dose effects" referred to biologic changes that occur in the ra...
متن کاملEnvironmental Chemicals: Evaluating Low-Dose Effects
Around the world, large-scale biomonitoring programs have provided extensive information about human exposure to a large number of environmental chemicals (Barr et al. 2010; Bilau et al. 2008; Churchill et al. 2001; Woodruff et al. 2011). As these programs extend to look at vulnerable populations, including pregnant women, fetuses, and the elderly, our knowledge of the widespread distribution o...
متن کاملTopic 3.15 Endocrine disruption occurring at doses lower than those predicted by classical chemical toxicity evaluations: The case of bisphenol A*
The meaning of the term “low dose” is discussed in relation to endocrine toxicity data for chemicals. Consideration is also given to experimental conditions likely to impinge on the interpretation and extrapolation of such low-dose effects, and the importance of gathering appropriate control data is emphasized. In the specific case of bisphenol A (BPA), it is concluded that despite the extensiv...
متن کاملDevelopment of a Research Strategy for Assessing the Ecological Risk of Endocrine Disruptors
Correlational evidence suggests that specific populations of animals have been, or currently are being, adversely affected by exposure to environmental contaminants that manifest effects through different endocrine systems. However, there currently are insufficient data to resolve the ecological risk associated with endocrine-disrupting chemicals (EDCs). In recognition of this uncertainty, the ...
متن کاملThe low down on low-dose endocrine disruptors.
most complex environmental health threats known today. By mimicking natural hormones such as estrogen and testosterone, these chemicals can interact with the body's endocrine system and exert toxic effects that may lead to reproductive and developmental abnormalities or cancer. In October 2000, the National Toxicology Program (NTP) and the NIEHS convened an independent panel of experts from aca...
