Abstract

Preservative treated wood is often used to construct planters, but there are concerns about components migrating from the wood into the surrounding soil where they might be selectively absorbed by plants. Potential for selective accumulation was evaluated by growing radishes, carrots and potatoes in copper azole (CA) treated Douglas-fir planters. Copper levels were higher in soil adjacent to CA treated wood, but did not differ in roots or tubers grown in treated or non-treated wood. Copper levels were elevated in carrot foliage which is not normally consumed.
