Arsenic in the Garden

Whaley Teaching GardenThis summer raised beds were created in Redeemer University's Teaching Garden using 4x4 pressure treated landscape lumber. Only flowers are planned for the beds. If vegetables were to be grown there might be some concern as the wood contains chromated copper arsenate which could leach into the soil and be absorbed by the vegetables; there is an article in Kitchen Gardener Magazine discussing this.

The article says the arsenic doesn't migrate much so wouldn't it be possible to put flowers next to the lumber and veggies in the center of the bed? It would look better than just veggies alone and I heard flowers like marigolds keep away bugs.
