Do CCA treated support stakes cause increased arsenic level in crops?
2003 - IRG/WP 03-50204
Trial of using CCA-C treated eucalypts stakes for supporting banana plants in Guangdong Province, China, began in 1998 and later it was expanded as a demonstration program of a joint International Tropical Timber Organization–Chinese Government timber preservation project in 2000. The greatest concern was whether the crop would be contaminated by the preservatives, arsenic in particular. Data fr...

Biological resistances of wood-metaborate composites using the borax solution system
2001 - IRG/WP 01-30259
Combinations of wood and metaborate composite were prepared from sapwood specimens of Japanese cedar (Cryptomeria japonica) and the borax and metallic salts system using the diffusion-penetrated process. Wood-metaborate composites were produced as follows: water-saturated specimens were first impregnated by a saturated borax solution and then diffuse-penetrated with Zn2+, Ca2+, or Pb2+ solution. B...

Detection and Assessment Healthy Situation of Poulus Euphratica Oliv. with Stress Wave
2009 - IRG/WP 09-20415
The defects of tree trunk of Poulus euphratica Oliv were inspected by stress wave method and diagnosed with transmission time and velocity. The reference values of transmission time of unit length and velocity from stress wave were used to assess the healthy situation of tree trunk. The goal is provide fast inspecting technology and assessment method for the historic trees in China. The results sh...

Bio-durability and weathering performances of cardanol-treated wood
2024 - IRG/WP 24-30809
Cardanol is an excellent insecticide, fungicide, and termiticide derived from thermally treated cashew nutshell liquid (CNSL) and has been extensively explored in the chemical industry and for medicinal uses. However, its potential for wood protection remains unexplored. This study aims to understand the bio-durability and weathering properties of cardanol-treated wood. The southern pine and yello...
