Army Corp given a year to recalculate coal mining impact on Black Warrior streams

Army Corps of Engineers to reassess coal mining impact on Black Warrior streams. Kent Faulk,, March 24, 2015. A federal appeals court this week gave the U.S. Army Corps of Engineers one year to go back and reassess the potential harm to streams in the Black Warrior River basin from coal mining after the agency admitted it made a mistake in calculating impacts. The U.S. 11th Circuit Court of Appeals reversed a federal judge's ruling from last May to dismiss a lawsuit filed in 2013 by the Black Warrior Riverkeeper, Defenders of Wildlife, the Southern Environmental Law Center and Public Justice.

Hormone-altering chemicals linked to attention problems, diabetes, other health problems

Chemical exposure linked to billions in health care costs. Elizabeth Grossman, National Geographic, March 5, 2015. Exposure to hormone-disrupting chemicals is likely leading to an increased risk of serious health problems costing at least $175 billion (U.S.) per year in Europe alone, according to a study published Thursday. National Geographic News.

EPA evaluates PBPK models

The use of PBPK models to inform human health risk assessment: case study on perchlorate and radioiodide human lifestage models. ED McLanahan, P White, L Flowers, PM Schlosser, Risk Analysis, February 2014. US EPA evaluated the human physiologically-based pharmacokinetic (PBPK) models for perchlorate and radioiodide for their ability to estimate the relative sensitivity of perchlorate inhibition on thyroidal radioiodide uptake for various population groups and lifestages. In this analysis, a six-step framework for PBPK model evaluation was followed, and with a few modifications, the models were determined to be suitable for use in human health risk assessment to evaluate relative sensitivity among human lifestages.
