Gasping for breath: Asthma-inducing diisocyanates enter our homes and schools

Johanna Katz is a Cornell Iscoll intern at EDF.  Jennifer McPartland, Ph.D., is a Health Scientist.

Toxic chemicals called diisocyanates are long-established as occupational hazards known to cause severe respiratory problems to workers who use or are otherwise exposed to them (see here).  In fact, diisocyanates are the number one cause of workplace-induced asthma (see here and here).  Recently, potential exposure of the general public to diisocyanates has grown, as these chemicals are increasingly used in consumer products.  This is certainly a troubling trend considering that the primary health effect of these chemicals, asthma, is a massive and growing public health problem, especially among children.  And some of the newest uses of diisocyanates are in products to which children are quite likely to be exposed.

Asthma is at an all-time high, affecting more than 24 million Americans, and creating astronomical health and productivity costs upwards of $20 BILLION each year.  And while diisocyanates are but one of many contributors to the increasing rate of asthma in the general population, we surely don’t need to be bringing more products containing such chemicals into our homes, schools, and workplaces. That will only make matters worse.

So what exactly are diisocyanate chemicals, where are they found, and what’s the federal government trying to do about them?  Read on to find out.  Read More »

Won’t we ever stop playing whack-a-mole with “regrettable chemical substitutions”?

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

In recent days, two compelling cases have surfaced of so-called “regrettable substitutions” – industry responding to concerns about the use of one dangerous chemical by replacing it with another that is less well-studied, or at least not currently in the crosshairs.

Case 1:  Chinese manufacturers of children’s jewelry, responding to concerns and restrictions on the use of lead in such products produced for export to the U.S., have replaced it with cadmium, a known human carcinogen and developmental toxicant that, if anything is even more toxic to kids than lead – but is not subject to any restrictions in such kids’ products.

Case 2:  American food product manufacturers, responding to concerns about the devastating effects on the lungs of workers exposed to diacetyl – an artificial butter flavoring used in many products, most notably microwave popcorn – have begun to replace it with closely related chemicals likely to break down into diacetyl or otherwise have similar effects.

Are we destined forever to play this dangerous variant on the game of whack-a-mole, or can something be done? Read More »

Questionable risk decisions under ChAMP: Chlorobenzenes Category

Cal Baier-Anderson, Ph.D., is a Health Scientist and Richard Denison, Ph.D., is a Senior Scientist.

Our analysis of EPA's risk decision under ChAMP for this category of toxic chemicals vividly illustrates how EPA has failed to adopt a health-protective approach to its screening of HPV chemicals.  Rather, it misclassifies or understates these chemicals' hazards, asserts that existing regulations are sufficient even when they are quite old or do not cover identified exposures, and naively assumes that children will not be as exposed as adults to consumer products used in the home unless they are intended for their use.  Finally, this case demonstrates that manufacturers are not reporting to EPA even readily available information on their chemicals' uses.  Read More »
