The U.S. District Court for the District of Columbia recently rejected industry challenges to an agency's decision to list the chemical styrene in the Twelfth Report on Carcinogens as "reasonably anticipated" to be a cancer-causing agent. A major styrene trade association and a manufacturer of the substance had sued the U.S. Department of Health and Human Services (HHS) for including styrene in the report.

As committees of the 113th Congress begin to implement their agendas, it is increasingly apparent that environmental and health standards, and the science serving as the basis for these protections, will remain a favorite target of anti-regulatory legislators. Last session's industry-supported proposals to change scientific assessment programs would undermine environmental, health, and safety standards, yet they are likely to reappear. Meanwhile, new investigations underscore that these measures ignore the real impediments to improving the credibility and usefulness of agency science and risk assessments.
