Cell Phones, Cancer and Precaution

written by Elise Miller, MEd

The National Toxicology Program’s study on the potential health impacts of cell phone radiation published at the end of May has been called a potential “game-changer” by some leading researchers in the field. The preliminary findings of this study, the largest of its kind ever conducted, indicate that male rats exposed to radio-frequency (RF) radiation emitted from wireless devices have an increased risk of developing brain cancer (malignant glioma) and tumors on the heart (schwannomas). This affirms the World Health Organization’s International Agency for Research on Cancer (IARC) decision in 2011 to classify RF radiation as “possibly carcinogenic” in humans. It also suggests that if IARC were to assess the emerging research from the last five years, it might have good reason to raise that classification to “probably carcinogenic.”

Top 10: July 2013

For the second quarter of 2013, we collectively selected ten topics from several dozen candidate news articles, journal articles, policy decisions and reports that have had a significant impact or are likely to have a significant impact on thinking and action in the field of environmental health. We consider these selections to be the biggest contributors toward new insights, toward changing the conversation or expanding the scope of the conversation on a topic to a new audience or awareness, or toward defining a new trend. Comments are welcome.

The selections, in no particular order:

  1. Chemical policy reform
    A significant development in federal chemicals policy reform occurred in late May when  Senator Frank Lautenberg (D-NJ) and David Vitter (R-LA) introduced a new, bipartisan bill called the Chemical Safety Improvement Act (CSIA). The introduction of the CSIA took many by surprise. Senator Lautenberg, who had been a champion for chemical policy reform for many years, passed away about a week later. CHE has compiled a selection of responses to this bill as well as links to other relevant sites for additional information: Chemical Policy Reform.
  2. Autism: New insights
    Several new studies have provided further understanding of environmental and genetic contributors to autism spectrum disorders. We list what we view as some of the most significant of these studies:

    1. Autism study finds link to environment, even in womb: A new study of twins suggests that environmental factors, including conditions in the womb, may be at least as important as genes in causing autism. See the study abstract: Genetic heritability and shared environmental factors among twin pairs with autism and related studies: Quantitative trait loci for interhemispheric commissure development and social behaviors in the BTBR T+ tf/J mouse model of autism and Methylomic analysis of monozygotic twins discordant for autism spectrum disorder and related behavioural traits.
    2. Study links autism with antidepressant use during pregnancy. See the study abstract: Parental depression, maternal antidepressant use during pregnancy, and risk of autism spectrum disorders: population based case-control study.
    3. Epilepsy drug in pregnancy tied to autism risk: Women who take the epilepsy drug valproate during pregnancy are three times more likely to have a child with an autism spectrum disorder, suggests new research based on close to 700,000 babies born in Denmark. See the study abstract: Prenatal valproate exposure and risk of autism spectrum disorders and childhood autism.
    4. US kids born in polluted areas more likely to have autism. See the study abstract: Perinatal air pollutant exposures and autism spectrum disorder in the Children of Nurses’ Health Study II participants.
  3. EHN special report: ‘chemicals of high concern’ found in thousands of children’s products
    An Environmental Health News analysis of thousands of reports from America’s largest companies shows that toys and other children’s products contain low levels of dozens of industrial chemicals. See the database: Children’s Safe Product Act Reports.

CHE’s Top 10 Environmental Health Stories, October through December 2012

For our second quarterly Top 10 list, we again selected news articles, journal articles, policy decisions and events that we consider “game-changers” in one way or another: they all have had a significant impact, or are likely to have a significant impact on thinking and action in the field; they’ve changed the conversation on a topic or expanded the scope of the conversation to a new audience or awareness; and/or they are likely to be pivotal in defining a new trend.

These were selected from several dozen candidates for this list:

  1. Workshop ‘Low Dose Effects and Non-Monotonic Dose Responses for Endocrine Active Chemicals’
    This groundbreaking international meeting in September moved the conversation about low-dose effects from endocrine disrupting chemicals significantly forward in re-examining the ways in which chemicals are tested for endocrine disrupting properties and how risk to human health is managed.
    See also a report from the World Health Organization: Endocrine disrupters and child health; movement from the EPA: EPA responds to scientists’ concerns, initiates new effort for low-dose, hormone-like chemicals and an article in Nature magazine: Toxicology: the learning curve.
