Podcast: How space travel affects human health

Have you ever wondered what it would be like to leave Earth?

Floating around the International Space Station and exploring new worlds may sound exciting, but space travel also poses a unique set of pretty intense health effects. Changes in gravitational force and radiation can cause physical harm to the body, while being in a small, isolated environment can take a toll on mental wellbeing. And that’s just the start of it!

Since the inception of our national and international space programs, researchers have been studying the myriad effects of spaceflight on health in hopes of developing better countermeasures as we venture farther into space.

In this episode of our podcast, we talked with Dr. Allie Anderson at the University of Colorado Boulder. Dr. Anderson describes “puffy face bird leg” syndrome (yes, that’s a thing) among other health impacts of space travel and what hot topics are keeping folks in space medicine busy.

Real progress on chemical reform

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

Links to blog posts in this series:  Part 1     Part 2     Part 3

[UPDATE 9-25-14: I have updated this post to link directly to a copy of the Udall-Vitter TSCA reform proposal, which – though not released by the Senators – is now available online here. My analysis of that proposal in this post remains unchanged. With a copy of the Udall-Vitter proposal now available online, I have also updated the introduction to my post, including removing some description of the back and forth that occurred last week].

The last week has seen the release of two proposals to reform the Toxic Substances Control Act (TSCA).  Senators Tom Udall (D-NM) and David Vitter (R-LA) have been negotiating for much of the last year on a bipartisan TSCA reform proposal that heavily reworks nearly the entirety of the Chemical Safety Improvement Act (CSIA, S. 1009), a bill originally introduced in May 2013 by Vitter and the late Senator Frank Lautenberg (D-NJ).  A notable exception is CSIA’s controversial preemption section, which was excluded from the scope of the Udall-Vitter negotiations.

On September 18, Senator Boxer (D-CA), Chairman of the Environment & Public Works Committee, released her own proposal, which is in the form of a redline of the Udall-Vitter proposal.

Both proposals are now available online, Udall-Vitter here and Boxer here.

This is the first of a series of three posts I’ll do examining these two proposals.  In this one I’ll take a deep dive into the Udall-Vitter proposal to show how it addresses the key concerns raised about CSIA and demonstrate that, by any objective measure, it represents a dramatic improvement over current federal law.  In the second post, I’ll examine the specific claims made by critics of the Udall-Vitter proposal.  In the third post, I’ll examine some of the features of the proposal from Senator Boxer, and conclude with why these two proposals present an opportunity.  Read More »

Nothing is forever – and chemical industry trade secret claims shouldn’t be an exception

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

A coalition of health, labor, environmental and environmental justice groups (including EDF), represented by Earthjustice, filed a petition today with the Environmental Protection Agency (EPA) that requests EPA establish a limit on how long information on chemicals submitted and claimed confidential by the chemical industry under the Toxic Substances Control Act (TSCA) can be protected from disclosure.

The petition asks EPA to close a loophole in its current regulations that by default grants indefinite protection for nearly all chemical information claimed confidential.  Because EPA’s only option under its current regulations is to challenge these claims on a case-by-case basis, industry bears no responsibility to ensure that its claims remain valid over time.  The lack of any expiration date for such claims has contributed to a large backlog of excessive and often unwarranted claims – the protection of which imposes large costs on EPA and the American taxpayer and denies public and market access to information that could lead to better-informed decisions about chemicals.

The petition filed today offers a simple solution, one called for in virtually every internal and external review of EPA trade secret policy conducted over the last several decades (see list at the end of this post):  EPA should alter its regulations to create a “sunset” for confidential business information (CBI) claims, which would expire after a set period of time (5 years is proposed) unless the claimant shows that continued protection is warranted.  This approach would allow true trade secrets to continue to be protected while providing public access to information that no longer warrants trade secret protection.  Read More »

A gift for mothers (and daughters, and all of us): New tools for breast cancer monitoring and prevention

Rachel Shaffer is a research assistant.

Our mothers are no doubt on our minds right now, after Mother’s Day weekend. And I am no exception, especially since, as I blogged about last year, this month is the anniversary of my own mother’s breast cancer diagnosis.

This year though, in addition to celebrating my mother’s recovery, I can find hope in a new report from researchers at the Silent Spring Institute that provides guidance to improve our ability to screen for and study potential breast carcinogens — thereby enhancing efforts to prevent this widespread disease. Good news, certainly… and a timely gift for all of the women in our lives.

This new report describes biomonitoring methods for 102 breast carcinogens with high exposure potential and identifies existing cohort studies into which these methods could be integrated immediately. These chemicals are among the 216 previously identified by the authors as chemicals linked to mammary gland tumors in rodents. By testing for exposure markers of these priority breast carcinogens in the population, researchers should be able to better identify and study high-risk groups, and regulators will be better able both to limit dangerous exposures and to demonstrate the public health benefits of these exposure reductions.

The full report is available online, but I want to highlight a few key themes that are particularly relevant to current scientific and political debates.  Read More »

Report: Staggering amounts of toxic chemicals produced across America

Alissa Sasso is a Chemicals Policy FellowRichard Denison, Ph.D., is a Lead Senior Scientist.

[Cross-posted from EDFVoices blog]

Recent spills in West Virginia and North Carolina cast a spotlight on toxic hazards in our midst. But as bad as they are, these acute incidents pale in scope compared to the chronic flow of hazardous chemicals coursing through our lives each day with little notice and minimal regulation. A new report by EDF, Toxics Across America, tallies billions of pounds of chemicals in the American marketplace that are known or strongly suspected to cause increasingly common disorders, including certain cancers, developmental disabilities, and infertility.

While it’s no secret that modern society consumes huge amounts of chemicals, many of them dangerous, it is surprisingly difficult to get a handle on the actual numbers. And under current law it’s harder still to find out where and how these substances are used, though we know enough to establish that a sizeable share of them end up in one form or another in the places where we live and work.

Our new report looks at 120 chemicals that have been identified by multiple federal, state and international officials as known or suspected health hazards. Using the latest, albeit limited, data collected by the U.S. Environmental Protection Agency, we identify which of these chemicals are in commerce in the U.S.; in what amounts they are being made; which companies are producing or importing them; where they are being produced or imported; and how they are being used. An interactive online map accompanying the report lets the user access the report’s data and search by chemical, by company, by state, and by site location.

Among our findings:  Read More »

Unnerving developments in the state of the evidence on developmental neurotoxicity

Rachel Shaffer is a research assistant.

Seven years ago, leading children’s environmental health experts Philippe Grandjean and Philip Landrigan published a groundbreaking review that identified five chemicals prevalent in the environment—lead, methylmercury, polychlorinated biphenyls (PCBs), arsenic, and toluene—as developmental neurotoxicants. In their follow-up review released last week, they have added six more chemicals—manganese, fluoride, polybrominated diphenyl ethers (PBDEs), chlorpyrifos, DDT, and tetrachloroethylene (PERC)—to this list. The implications of early-life exposures to these common compounds, say the authors?  A “global silent pandemic of neurodevelopmental toxicity.”  Read More »
