Just what the doctor ordered: EPA tells BP to use less toxic oil dispersants in the Gulf

This just out:  The Washington Post is reporting that EPA has given BP 24 hours to identify and locate a supply of a less toxic dispersant to be applied to the Gulf oil spill, and to begin using it within an additional 72 hours.

As noted in my last post, EPA has identified numerous alternative dispersants that are both less toxic and more effective than those on which BP has been relying to date — more than 600,000 gallons of which have already been released into Gulf waters.  The Post also notes that some forms of the initial dispersants, sold by Nalco under the trade name Corexit®, were banned by the British government more than a decade ago.

Compounding the problem: Why aren’t we using the safest and most effective dispersants in the Gulf?

Imagine learning you have a serious disease.  Your doctor decides to treat you with a drug, noting it could have some bad side effects.  He also plans to inject you with the drug, even though it’s only been used orally before now.  That makes you nervous enough to ask for the name of the drug. “Sorry, I can’t tell you,” he says.  “It’s proprietary.”  Even if you trust your doctor, you’re now left with no way to investigate the risks and tradeoffs you’re facing.

Imagine how mad you’d be if you learned your doctor hadn’t told you there were other drugs that not only had fewer side effects, but were more effective in treating your condition.  And then you learn he’s on the Board of Directors of the company that makes the drug he prescribed.

Now consider that the patient is the Gulf of Mexico, the doctor is BP, and the drug is the oil dispersants, sold by Nalco under the trade name Corexit®, more than 500,000 gallons of which have been applied to date, with no end in sight.  Read More »

Are we ready to get sensible about triclosan use?

By / Published: April 9, 2010

Cal Baier-Anderson, Ph.D., is a Health Scientist.

Yesterday the Washington Post reported that the Food and Drug Administration (FDA) is acknowledging that new research raises “valid concerns” about the possible health effects of triclosan, an antimicrobial chemical that can be found in dozens of consumer products as diverse as soaps, personal care products, cutting boards, plastic sandals and even bath towels.

Originally developed as a surgical scrub for use by doctors and nurses, the burgeoning uses of this pesticidal chemical have hugely expanded human and environmental exposures.  With little evidence of any actual public health benefits from such uses, FDA along with the Environmental Protection Agency (EPA) and the Consumer Product Safety Commission (CPSC) should move quickly to limit triclosan use.  Only those uses that have a demonstrable public health benefit, when weighed against potential health and environmental risks, should be allowed.

Blown away: EDF investigation of asbestos in hair dryers

By / Published: April 1, 2010

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

On March 30, the Washington Post ran the following story:
[Clarification added 4/2/10:  I have now learned that the text below is actually a summary of two Post articles, which ran in Environment magazine (April 1979, p. 21).  Click these links for previews of the 3/29/79 and 3/30/79 Post articles, available for purchase from its archives.  Apologies for the incorrect information.]

Reporters from WRC-TV, the NBC Station in Washington, D. C., spent nine months investigating asbestos-lined hair dryers after the Consumer Product Safety Commission declined to do so.  The station, in collaboration with the Environmental Defense Fund, conducted an investigation which culminated in an uninterrupted 15-minute news segment detailing the results of their findings.  Read More »

The Katrina chronicles: Formaldehyde-laced trailers set to claim another set of victims

By / Published: March 14, 2010

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

The Washington Post ran a front-page article Saturday, written by Spencer Hsu, which reported the auction sale by FEMA of most of the 120,000 notorious formaldehyde-tainted trailers it had purchased five years ago to house the victims of Hurricane Katrina.

The article cites FEMA as saying that “wholesale buyers from the auction must sign contracts attesting that trailers will not be used, sold or advertised as housing, and that trailers will carry a sticker saying, ‘Not to be used for housing’.”

Think that’s likely to be enough?  Read More »

Toxic Chemicals in Consumer Products: More than Just Consumer Exposure

By / Published: February 8, 2010

Cal Baier-Anderson, Ph.D., is a Health Scientist.

An article recently published in the journal Macromolecules reports on the development of a new process that the authors claim can prevent the migration of phthalates from PVC plastic.   This “breakthrough” will undoubtedly be used to argue that industry should be allowed to continue to use a retinue of toxic chemicals in the manufacture of PVC destined for use in a broad variety of applications.

Concern for consumer exposures is often the main argument made against the use of toxic chemicals in consumer applications.  With evidence of exposure to chemicals like phthalates in nearly everyone who has been tested, including pregnant women, this is understandable.

But even if the new claims are proven to be true, there are many other reasons we need to find safer substitutes for such chemicals: worker exposures, environmental releases and end-of-life recycling and disposal issues, to name a few.  The potential impacts from continued use of toxic chemicals must be examined across their entire lifecycle.
