Exposure Science and the Exposome: An Opportunity for Coherence in the Environmental Health Sciences: Exposure scientists Lioy and Rappaport describe how studying the “exposome” could be a major boon to research in environmental health, allowing quicker identification of potentially harmful agents, and deeper and more directed study of what those agents are.

Anti-PVC push in health care grows: The American Public Health Association this week passed a resolution urging facilities such as hospitals, schools and nursing homes reduce the amount of PVC they use, especially with phthalates.

Although residues of individual pesticides are decreasing, the total number of pesticide residues is increasing (see this chart by PAN Europe), potentially resulting in a net increase in pesticide residues on food. The total toxicity of this mix is not a factor in assessing residue safety.

The Emerging Role of EDCS in Insulin Resistance: Implicating Nonalcoholic Fatty Liver Disease: Evaluation of whether or not EDCs may play a role in the pathogenesis of NAFLD, a condition related to insulin resistance and apparently affecting 30-45% of the western population.

Next-generation brominated flame retardants found in Nordic environment: Researchers have found emerging flame retardants, increasingly used since the phase-out of PBDEs, in samples from all environmental media collected in the Nordic region.
