I have been using these lists for a few years now to judge when buying organic produce makes sense. According to the EWG (Environmental Working Group) calculations, if you consume 5 servings of fruit and vegetables from the clean 15 instead of the dirty dozen (12) you will consume 92% less pesticides. To read more about EWG and the methods used in the tests click here.
If you can't buy organic produce, remember it is much better to eat fresh fruit and vegetables (even if they are on the list of dirty dozen) than to eat processed foods. Actually, the least expensive way to get your fruit and vegetables is to grow them in a backyard garden. You can learn about growing your own produce on my Backyard Gardening Blog.
Until you can get your own garden going here are the lists from EWG:
