Do these chemicals make me look fat?

Woman in mirrorJennifer McPartland, Ph.D., is a Health Scientist.

My colleague Richard Denison at EDF ended his last blog post asking, “The new study [Environmental Chemicals in Pregnant Women in the US: NHANES 2003-2004] leaves me with one question:  How many more such wake-up calls do we need before our government enacts policies to ensure the safety of chemicals to which we are exposed?”

Maybe this will help shake us awake!  The obesity epidemic in the United States is increasing at alarming rates.   So too is an associated disease, type 2 diabetes.  Researchers have attributed 70% of the risk associated with developing type 2 diabetes with being overweight or obese, a risk that increases by 4.5% for every 2.2 pounds of weight gained over 10 years.

A healthy diet and hitting the gym should keep these diseases at bay, right?  Certainly proper nutrition and exercise are good and important habits for controlling our weight and maintaining overall health.  But what if, despite all such efforts, there are contributing factors outside of our control, and even outside of our genetic makeup?  And what if those potential factors are found in us, on us, and all around us?

New research suggests that chemicals found in our environment and in everyday products may play a significant role in packing on the pounds.  Read More »

New study demands far more than a pregnant pause: Expectant women carry dozens of toxic chemicals in their bodies

Richard Denison, Ph.D., is a Senior Scientist.

A long-awaited study documenting the presence of multiple toxic chemicals in the bodies of pregnant women was published today in Environmental Health Perspectives.  The study, conducted by researchers at Program on Reproductive Health and the Environment at the University of California, San Francisco, analyzed the most recent comprehensive biomonitoring data collected by the Centers for Disease Control (CDC) as part of its national human biomonitoring program.

The new study found widespread exposure of pregnant women to a large fraction of the chemicals for which biomonitoring is conducted, including chemicals that are currently in widespread use, such as brominated flame retardants (known as PBDEs) used in furniture foam and plastics, perfluorinated chemicals (PFCs) used in everything from packaging to textiles, and a pervasive environmental contaminant used in rocket fuel (perchlorate).

In particular the study noted:  “Certain PCBs, organochlorine pesticides, PFCs, phenols, PBDEs, phthalates, polycyclic aromatic hydrocarbons (PAHs) and perchlorate were detected in 99 to 100% of pregnant women.” (emphasis added)  Read More »

Regulating nano-silver as a pesticide

John BalbusCal Baier-Anderson, Ph.D., is a Health Scientist.

In May 2008, the International Center for Technology Assessment (ICTA) submitted a petition to EPA requesting that it regulate nano-silver used in products as a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).  The petition calls on EPA to take the following specific actions:

  1. Classify nano-silver as a pesticide.
  2. Determine that nano-silver is a new pesticide and require its registration as such.
  3. Analyze the potential risks of nano-silver to human health and the environment.
  4. Take enforcement actions against nano-silver-containing products being sold illegally without EPA approval under FIFRA. Read More »
