Margaret Wente in the Globe and Mail:
Ms. Williams is right that our bodies contain trace amounts of pretty much everything that’s in our environment. But toxicity is a matter of degree. And technology is so advanced that we can measure trace amounts in parts per trillion. As yet, research has found no trace of harm. For example, after a comprehensive review of environmental causes and risk factors for breast cancer, the U.S. Institute of Medicine found no conclusive link between any of these chemicals and an increased risk of breast cancer. According to Scientific American, “some research shows the toxic load in breast milk to be smaller than that in the air most city dwellers breathe inside their homes.”

This is not to say there’s no impact from environmental factors. But these effects are small and uncertain. To eliminate them all, we’d have to eliminate modernity and return to being hunter-gatherers again.
But I’m afraid chemophobia is here to stay. Fear sells. Fear of chemicals manufactured by rapacious, greedy, money-sucking capitalist enterprises sells even better. Fear is is the main product peddled by interest groups such as the Environmental Defence Fund, which has been quite successful at marketing the notion that invisible dangers lurk all around us. The media love this stuff because it makes for easy headlines: If your shampoo doesn’t kill you, your lipstick will! Fear is a staple of celebrity experts like Dr. Oz, who has advised readers to avoid toxic sales receipts from fast-food restaurants and gas stations.
