James Hamblin sinks his teeth into the so-called “silent pandemic” of toxins hidden in our everyday items. A team of researchers identified a dozen common poisons – such as ethanol, lead, and mercury – that leech IQ points:
The greater concern lies in what we’re exposed to and don’t yet know to be toxic. Federal health officials, prominent academics, and even many leaders in the chemical industry agree that the U.S. chemical safety testing system is in dire need of modernization. Yet parties on various sides cannot agree on the specifics of how to change the system, and two bills to modernize testing requirements are languishing in Congress. [Mount Sinai’s Philip] Landrigan and [Harvard’s Philippe] Grandjean’s real message is big, and it involves billion-dollar corporations and Capitol Hill, but it begins and ends with the human brain in its earliest, most vulnerable stages. …
Economist Elise Gould has calculated that a loss of one IQ point corresponds to a loss of $17,815 in lifetime earnings. Based on that figure, she estimates that for the population that was six years old or younger in 2006, lead exposure will result in a total income loss of between $165 and $233 billion. The combined current levels of pesticides, mercury, and lead cause IQ losses amounting to around $120 billion annually—or about three percent of the annual budget of the U.S. government.
Low-income families are hit the hardest. No parent can avoid these toxins—they’re in our couches and in our air. They can’t be sweated out through hot yoga classes or cleansed with a juice fast. But to whatever extent these things can be avoided without better regulations, it costs money. Low-income parents might not have access to organic produce or be able to guarantee their children a low-lead household. When it comes to brain development, this puts low-income kids at even greater disadvantages—in their education, in their earnings, in their lifelong health and well-being.
