Biological screening assays of wood samples treated with creosote plus chemical additives exposed to Limnoria tripunctata
1980 - IRG/WP 408
Laboratory methods for exposure of treated wood coupons to Limnoria tripunctata are described. Chemical additions to creosote were screened using this method. Three pesticides, Endrin, Kepone, and Malathion proved particularly effective. The addition of varying percentages of naphthalene to creosote using several treatment methods are currently being assayed. Results to date show that the coupons ...

The field performance of CCA-C treated sawn refractory softwoods from North America
1997 - IRG/WP 97-40085
Approximately 15% of the total volume of wood treated in the United States consists of difficult to treat softwoods known as "refractory softwoods". The long term positive performance record of CCA treated sawn material is based upon the testing of yellow pine sapwood stakes with only limited field data available for sawn refractory softwoods. As a result, the existing North American wood preserva...
