Sludging through the nano lifecycle: Caution ahead

By / Published: September 23, 2010

Researchers at Virginia Tech have identified and characterized silver nanoparticles (AgNPs) in the sewage sludge produced by an operating municipal wastewater treatment plant.  The study is notable in several respects:  It is the first time AgNPs have been detected in a field-scale study, one of a real-world operation representative of a real-world exposure scenario to boot.  It shows that silver can exist in wastewater treatment products as nanoparticles.  It indicates such particles may be most likely to partition to sludge under common treatment technologies.  And it suggests that silver may be chemically transformed in the course of wastewater treatment.

The study did not demonstrate that the AgNPs detected in the sludge originated from products containing such nanoparticles, as some news stories have suggested, although the authors indicate such a source “is likely.”  But the findings have important implications for nano safety nonetheless.  Read More »

Voters say “I am Not a Guinea Pig”: New poll shows strong, deep, bipartisan support for comprehensive chemical safety overhaul

By / Published: September 14, 2010

Today, the Safer Chemicals, Healthy Families coalition released the results of a poll conducted by the well-respected Mellman Group in key swing districts around the country.  It shows that Americans of all stripes and political persuasions overwhelmingly support a major overhaul of our nation’s chemical safety law.

A whopping 84% of likely voters say that “tightening controls” on chemicals is important, with 50% calling it “very important.”  That response includes 75% of Republicans and 82% of Independents.  When provided with a brief description of the reform proposals recently introduced into Congress, seven in 10 likely voters indicated they favor the legislation.

But here are the real kickers:  When given more detail about its specific provisions, support for the legislation went up significantly, from 71% to 82%.  And the largest increases in support were seen among Republicans (a 25% increase) and those in a household dependent on the chemical industry (22% increase).  Read More »

State-level nano regulation: Yes, indeed, the industry “should have seen it coming” – it caused it!

By / Published: September 10, 2010

I just read an interesting column by John DiLoreto, CEO of NanoReg, that appears online at Nanotechnology Now.  It’s titled “We Should Have Seen It Coming: States Regulating Nanotechnology.”  It nicely describes the important role states play in advancing environmental policy and regulation – especially when the feds are asleep at the wheel.  And it also gives a neat rundown of the various state actions aimed at nanomaterials that are underway.

But, search as I might, I couldn’t find a single acknowledgment in Mr. DiLoreto’s latest column – or in his earlier related column titled “What Drives the Regulation of Nanomaterials?” – of the role the nanotechnology industry itself played in bringing all of this on itself.

That’s quite an omission, in my view, given that the industry’s actions (or, more accurately, the lack thereof) played a central role in getting us to where we are (or, more accurately, aren’t) today on nanotechnology oversight.  That includes driving states to feel they had to step in to fill the federal void.   Read More »

States unite to support TSCA overhaul; chemical industry is increasingly odd one out

By / Published: August 31, 2010

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

Yesterday, at its annual meeting, the Environmental Council of the States (ECOS) unanimously adopted a resolution calling on Congress to enact strong and comprehensive reform of the Toxic Substances Control Act (TSCA).

ECOS is comprised of the heads of the environmental agencies in the U.S. states and territories.  Its new resolution includes major elements of reform that EDF and the other health and environmental members of Safer Chemicals, Healthy Families have been calling for.  Read More »

Affirming a thing of beauty: Comments filed today support new EPA CBI policy

By / Published: August 25, 2010

Today EDF joined with Earthjustice and 24 other health, labor and environmental organizations in filing comments with EPA that support its recently announced policy change restoring the public’s right to know the identities of all chemicals for which health and safety data have been submitted to the agency.

I have already done a post on the details of EPA’s new policy, which I termed “a thing of beauty.”  The comments we filed today – in response to EPA’s request when it issued its new policy back in May – make clear that the policy reflects both the clear meaning of the Toxic Substances Control Act (TSCA) and the clear intent of its drafters.   Read More »

EPA seeks to improve TSCA data reporting; a real litmus test looms for the chemical industry

By / Published: August 20, 2010

While I was on vacation last week, EPA’s proposed rule to improve chemical information reporting under its so-called Inventory Update Rule (IUR) was finally published in the Federal Register.  (I say “finally” because the proposal languished for almost 6 months over at OMB, nearly double the 90 days such mandatory reviews are supposed to take.  That unfortunate delay is curious given the relatively modest changes that appear to have been made by OMB – mostly limited to compelling EPA to shift a few elements from proposals to options open to comment, and requiring EPA to expand the range of issues on which it now seeks comment.)

I won’t summarize the EPA proposals here; EPA’s factsheet does a good job of that, and Daniel Rosenberg at NRDC has also nicely recapped the proposal on his blog.  Suffice it to say that the proposed changes would go far to address the many failings of the current IUR, which amply manifested themselves in the last reporting cycle and severely hampered EPA’s ability to assess high production volume (HPV) chemicals under its ill-fated ChAMP Initiative.

So how will the chemical industry react?  Here’s why I’ll be watching intently.  Read More »
