This is not good. But doing something about it (i.e. internalizing the externality) is too offensive to corporate Canada â€“ and apparently from the article, corporate everywhere. Call it “smart regulation” or “risk management”, the way our regulatory system is set up means that the bodies have to pile up for the sake of sufficient scientific evidence before we regulate (oh, and even that could probably be challenged under international trade rules).
TORONTO â€” Environmental exposure from hundreds of industrial chemicals could be damaging the developing brains of children worldwide, but few of the potentially toxic compounds are regulated because too little is known about their effects, researchers say.
In a paper published on-line Wednesday in The Lancet, two specialists in environmental medicine (each of whom have spent decades studying the effects of lead and mercury exposure on the fetus and children) compiled a list of 201 industrial chemicals they say have the capacity to cause irreparable damage to the developing human brain.
Lead author Dr. Philippe Grandjean, chair of environmental medicine at the University of Southern Denmark, said he and co-author Dr. Philip Landrigan of New York’s Mount Sinai School of Medicine both had similar experiences while studying the neurotoxicity of lead and mercury.
â€œFirst, things were seen in adults and later on, the disease was seen in children born to pregnant women or children exposed in early childhood at much lower doses,â€ Dr. Grandjean said Tuesday from Copenhagen. â€œLater on, it was found that these effects were more serious and they were permanent (in children).â€
â€œAnd then we wondered: Is this only happening with mercury and lead?â€
The two researchers then undertook an extensive review of published data on chemical toxicity to create a list of those agents most likely to harm the developing brain. Their tally of 201 compounds includes everything from arsenic to benzene and phenol. About half of the chemicals are ubiquitous in industrial processes and products â€” and could make their way into the environment through air, water and food.
But because there is a dearth of research on the effects of these chemicals specifically on children, their use has not been regulated in the same way as mercury, lead and PCBs.
Dr. Grandjean and Dr. Landrigan argue that the lack of international regulation is putting children around the globe at potential risk, and they worry whether exposure to such chemicals could be behind such conditions as autism and attention deficit hyperactivity disorder. (The cause of these conditions remain unknown.) Calling the potential for harm a â€œsilent pandemic,â€ the researchers are urging governments worldwide to begin strictly controlling these chemicals, instead of waiting for years of testing to provide definitive scientific proof that they are either harmful or benign.
â€œWhat we are saying is we cannot afford to wait decades because that way we will expose another generation of children to toxic chemicals that will affect their brains permanently,â€ Dr. Grandjean said. â€œWe cannot afford to do that.â€
â€œIn the knowledge society of today â€” and certainly in the future â€” we need all the brain power we have . . . It’s a crucial resource that we need to protect and we’re behaving as if it’s not important at all.â€
Perhaps the answer is just to move to a better neighbourhood and put your kids in a decent private school. Oh wait, not everyone can do that. Never mind.
