There's an interesting debate emerging in the public health world. It has to do with whether we need to rejigger our thinking about the risks pesticides and other chemicals pose to children's health.
Traditionally, we've had a "disease-oriented" approach, assessing risk based on the severity of a health outcome (think birth defects or cancer). But earlier this month a provocative Environmental Health Perspectives article argued that a "population approach" might be wiser — meaning that even when a health effect is not severe, if it's affecting a huge number of our children (think dropping IQs), we should be paying attention.
