Chromated copper arsenate (CCA) wood preservatives contain chromium, copper and arsenic. Pressure-treated wood containing CCA is no longer used in most residential settings. The chemicals in CCA-treated wood have been shown to leach into the surrounding environment and can transfer to the skin when people touch the wood. CCA residues on the skin typically result in minimal exposure. …

from each of these types of treated wood. The exact amount of preservative lost depends on how well the wood was treated, how old it is, and the environment around the pole. Most of the metal losses from CCA-C, ACZA and/or ACQ-B occur during rain events. While each of these preservatives behaves somewhat differently, the environmental risks are similar and the following discussion focuses on
