Description:
EPA conducted a study to evaluate the effect of coatings on dislodgeable arsenic, chromium, and copper residues on the surfaces of chromated copper arsenate (CAA) treated wood. Dislodgeable CCA, determined by wipe sampling the wood surfaces, was the primary evaluation criterion for the coatings tested in this study, due to the potential for ingestion of CCA chemicals by hand-to-mouth activities of you children that contact CCA treated wood. CCA has been used extensively for construction of decks and play structures that may have a long service life and therefore may pose a potential exposure route for CCA residues for many years to come. The tests found that stains performed better than sealants; products with acrylic performed better than products without acrylic; non-alkyd products performed better than products with alkyd; film forming products performed better than penetrating products; and, multi-coat products performed better than single coat products.
