ost Americans believe that if a chemical is in their cosmetics, their coat, or their couch, someone is making sure it’s safe for their health. In reality, little toxicity information or regulation is required for 80,000 industrial chemicals used in commerce in the United States. To address this, legislation to update the inef ective 1976 Toxic Substance Control Act (TSCA) is currently moving th...

The toxic metal, lead, is associated with aggressive behavior, delinquency, and attention disorders in boys between the ages of 7 and 11, according to a study by Herbert Needleman published in 1996 in the JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION (JAMA).[1] Aggressive behavior, delinquency and attention disorders in youth are, themselves, predictors of criminal behavior later in life.[2] This...

P-List (Acutely Toxics)

Renal response to environmental toxics

Several characteristics of normal renal function increase the risk to the kidney of damage by environmental toxins. Due to the magnitude of renal blood flow the total amount of noxious substance delivered may be disproportionately high. Furthermore, the capacity to concentrate substances within the kidney by processes of filtration, reabsorption and secretion has the potential to increase the t...

EHPnet: Taking Inventory of Toxics

Many cellular systems rely on the ability to interpret spatial heterogeneities in chemoattractant concentration to direct cell migration. The accuracy of this process is limited by stochastic fluctuations in the concentration of the external signal and in the internal signaling components. Here we use information theory to determine the optimal scheme to detect the location of an external chemo...
