EPA identifies another risky chemical: Can it succeed in using TSCA to restrict it?

Lindsay McCormick is a Research Analyst.

Last week, EPA released a risk assessment on the chemical N-Methylpyrrolidone (NMP).  NMP is produced and imported into the U.S. in huge quantities (184 million pounds reported in 2012), and has a variety of uses including petrochemical processing, making plastics, and paint stripping.

Experiments in laboratory animals demonstrate that exposure to NMP during pregnancy leads to adverse developmental outcomes in the offspring, such as low birth weight, skeletal malformations, and mortality (see here and here).

EPA’s assessment focused exclusively on NMP exposure from its presence in products used to remove paint and other coatings.  Because of NMP’s potential to disrupt fetal development, EPA assessed exposures in women of childbearing age.

EPA found that exposure to NMP-based paint strippers in women of childbearing age beyond four hours per day presents risks that cannot be mitigated from use of protective gear such as gloves and respirators.  Risks obviously could be greater, even for shorter exposure times, if protective equipment is not consistently used.   Read More »

More “A”-level work under REACH: ECHA adds eight chemicals to the Authorization List

Allison Tracy is a Chemicals Policy Fellow.

The European Commission has formally added eight more chemicals to the list of chemicals subject to authorization under the European Union’s Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH).  These eight chemicals, which were proposed for addition to the Authorization List (or Annex XIV) in December 2010, join the six inaugural chemicals that were formally listed last February (see EDF’s blog post on that occasion).  The full Authorization List is available on ECHA’s website; the list also specifies the corresponding sunset date by which time uses of a chemical must cease unless specifically authorized.

REACH starts to earn its "A": 20 chemicals headed to the Candidate List and 13 to Authorization

Allison Tracy is a Chemicals Policy Fellow. Richard Denison, Ph.D., is a Senior Scientist.

The European Chemicals Agency (ECHA) has been busy this week implementing the EU's chemical regulation, REACH (short for Registration, Evaluation, Authorization and Restriction of Chemicals).

On Monday, ECHA announced it has added 20 more Substances of Very High Concern (SVHCs) to REACH's Candidate List.  These SVHCs are now eligible for later addition to Annex XIV, the list of SVHCs subject to Authorization.

Separately, the agency today forwarded its final recommendation that 13 chemicals already on the Candidate List be formally added to Annex XIV.  (We had blogged earlier about ECHA's initial recommendation proposing these 13 SVHCs for Authorization.)  If the European Commission confirms this addition, after a specified sunset date, the use of these will be allowed only if specifically authorized by EU authorities.  Read More »

Twin dangers from TCE: Widespread exposure, and now a strong link to Parkinson disease

Jennifer McPartland, Ph.D., is a Health Scientist.

A study published online in the Annals of Neurology last week, “Solvent Exposures and Parkinson Disease Risk in Twins,” adds to scientific evidence linking exposure to the solvent trichloroethylene, or TCE, and other common solvents with onset of Parkinson disease.  Parkinson disease is a debilitating condition well known for symptoms of trembling but can also include slowed motion, impaired posture and balance, and loss of automatic movements (e.g. blinking, arm swaying when walking).  Most unfortunately, it has no cure. 

According to the authors, this new twin study is the first confirmation in a population-based study of a significant association between exposure to TCE and incidence of Parkinson disease.    Read More »
