Copper migration from preservative-treated Douglas-fir decking: models vs laboratory leaching data
2024 - IRG/WP 24-50390
The ability of a model to predict copper migration from Douglas-fir treated with organic metallic substances into a freshwater slough was evaluated against data generated through simulated overhead leaching. The model predicted very high loadings of ammoniacal copper zinc arsenate, alkaline copper quaternary or copper azole that had the potential to impact water quality while data from the exper...

Quantifying metal migration from a deck constructed with copper-azole-treated lumber
2024 - IRG/WP 24-50391
Soluble copper or micronized copper wood preservatives are the most common available wood preservative systems for residential applications in the United States. Copper containing wood preservatives have been scrutinized for their potential negative impacts on the environment, across many jurisdictions. Concerns arise from the potential for preservatives to migrate out of treated wood upon water e...

Quantitative assessment of wood preservative emissions to waterways
2024 - IRG/WP 24-50393
The Organisation for Economic Co-operation and Development (OECD) Emission Scenario Document (ESD) for Wood Preservatives provides methods to quantify the release of active substances from treated wood for various scenarios including sheet pilings in a flowing waterway (OECD 2013). The ESD is used for environmental risk assessment of wood preservatives according to the Biocidal Products Regulation...
