Non-CCA Wood Preservatives

At NPIC our goal is to promote informed decision-making based on sound science. In response to several inquiries about the potential health concerns associated with treated wood, NPIC presents this collection of science-based articles, fact-sheets and resources.

This page represents one subtopic, other topics are available at the main index page.

For information concerning CCA treated wood (wood treated with copper, chromium and arsenic) please see our CCA Treated Wood page.

If you have questions about this, or any pesticide-related topic, please call NPIC at 1-800-858-7378 (seven days per week, 6:30am-4:30pm PST), or send an email to npic@ace.orst.edu.
