From the Atlantic article:

There are the more immediate health benefits of buying organic: you'll avoid the chemicals, preservatives, and hormones that conventional farms often use to treat their foods. In the Stanford study, just 7 percent of organic foods were found to have traces of pesticides, compared to 38 percent of conventionally-farmed produce. Again, that doesn't mean organic foods will supercharge your health -- you'll just be at less risk of exposure to potentially harmful substances, for whatever that's worth to you. Quantifying that benefit is a contentious area and certainly worthy of more research.

Listen to what Bruce Ames (professor emeritus of biochemistry at UC Berkeley and senior scientist at Children's Hospital of Oakland Research Institute) had to say on this mornings Forum: http://www.kqed.org/a/forum/R201209051000

Basically, don't worry about those traces of pesticides. He explains it better than me. Listen.
