body burden

I couldn't bring 9-month-old Connor with me when I attended my first POPs treaty meeting in Bonn, so I brought my breastmilk pump instead. I vividly remember struggling with my rusty German to convince the women in the conference center kitchen to store my milk in the deep freeze.

As a nursing mother, participating in the POPs treaty meetings took on a very personal dimension. Here's why: persistent chemicals build up in food chains across the globe, and this is a key reason the treaty exists. Human milk — nature's perfect food for infants — is at the very top of the food chain. This is why POPs show up so often in breastmilk.

Last week, researchers found a host of toxic chemicals in the bodies of pregnant women throughout the U.S. Industry reps quickly trotted out their favorite messages in response: "Chemicals are a fact of modern life," "just because toxins are in your body doesn't mean they'll hurt you," and "the levels are too low to matter - researchers have new tools that can measure extremely low levels." 

The fact is, low levels of chemicals in the womb can matter a whole lot. And studies like last week's make the chemical industry very, very nervous.
