Study raises big questions about worker protection in nanotech labs

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

When it comes to chemical exposures, workers are on the front line.  Workers are usually the most likely to be exposed to harmful levels of chemicals, because they are the ones producing, processing, handling, sampling and measuring, transferring and transporting chemicals in larger and more concentrated quantities.

Throughout history, workers have been the canaries in the coal mines; the first to exhibit the health effects of hazardous chemical exposures, from scrotal cancer in chimney sweeps, to mesothelioma in shipyard and construction workers to liver cancer in vinyl chloride workers.

For these reasons, EDF has argued that workers handling or otherwise likely to be exposed to nanomaterials must be protected from harm (see our earlier posts here, here and here).  Now, a new government study published in the respected journal Environmental Health Perspectives reveals that certain comfortable assumptions about nanomaterial laboratory safety may be downright wrong.

How should the problem of “secret chemicals” be addressed?

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

A front page article by Lyndsey Layton in yesterday’s Washington Post – spurred by an intriguing new report by the Environmental Working Group – did a great job of exposing the extent to which the identities of chemicals in widespread use are hidden from view, and of exploring some of the many adverse consequences.

Neither the article nor the report, however, had much to say about how this problem of excessive reliance on confidential business information (CBI) claims by industry might be solved, especially in the context of impending reform of the Toxic Substances Control Act (TSCA).

In this post I’ll provide some concrete proposals for addressing this serious problem.

EPA deserves an “A for Effort” for its new Chemical Action Plans

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

Just squeaking in under its self-imposed deadline, late on December 30 EPA issued the first batch of chemical action plans it has promised under its enhanced chemical management program.  In doing so, EPA has signaled its intention to do all it can using its existing authority under the Toxic Substances Control Act (TSCA) – even as it also makes clear that authority is “both outdated and in need of reform.”  To my ear, that strikes just the right balance.
