EPA new strategic plan for evaluating the toxicity of chemicals
March 26, 2009EPA is releasing a new approach to advance the science upon which the agency bases its regulatory decisions and policies, resulting in better protection for human health and the environment. Today, EPA released the "U.S. Environmental Protection Agency's Strategic Plan for Evaluating the Toxicity of Chemicals."
This strategic plan outlines a new scientific approach that will allow EPA to assess risks from many chemicals and mixtures by adopting new toxicity testing methods that use recent advances in molecular biology, genomics, and computational sciences.
When fully implemented, EPA will be able to screen thousands of environmental chemicals quickly for potentially harmful effects. The strategic plan will also allow EPA scientists to look at how children may react differently to the same chemicals as adults, thus providing better health protection for children.

Toxic chemicals affect steroid hormones differently in humans and invertebrates
In a study with important consequences for studies on the effects of chemicals on steroid responses in humans, a team of French and American scientists, including Michael E. Baker, PhD, professor in UC San Diego's Department of Medicine, Division of Nephrology-Hypertension, have found that - contrary to earlier assumptions - enzymes used for the synthesis of steroids in insects, snails, octopuses and corals are unrelated to those used in humans.

A study comparing breastfed and formula fed infants across time showed that the known beneficial effects of breastfeeding are greater than the potential risks associated with infant exposure to chemicals such as dioxins that may be present in breastmilk.
NTP finalizes report on Bisphenol A
Current human exposure to bisphenol A (BPA), a chemical used in many polycarbonate plastics and epoxy resins, is of "some concern" for effects on development of the prostate gland and brain and for behavioral effects in fetuses, infants and children, according to a final report released today by the National Toxicology Program (NTP).
