I'm a licensed pesticide applicator, the things that break down chemicals and pesticides the most are heat, light, and water, along with time. If it's fully composted, it should be fine, the chemicals used these days are not very toxic to begin with, and are heavily diluted, and all the rain, heat, and sunlight should take care of them. If any doubt, you can always have a soil test done.
