An interim report on studies of the tolerance by Sphaeroma (Crustacea: Isopoda) of CCA-treated timber
1982 - IRG/WP 491
In Papua New Guinea any untreated timber exposed to seawater close to mangrove stands is liable to be attacked in the intertidal zone by the crustaceans Sphaeroma terebrans or Sphaeroma triste. Even CCA-treated timber is sometimes vulnerable. The mouth-parts of these animals are adapted for boring, but whether wood particles are ingested remains to be resolved. Some limbs of Sphaeroma terebrans ap...

Marine exposure assessment of the natural resistance of a number of lesser known species of tropical hardwoods to teredinid and limnoriid borers
2004 - IRG/WP 04-10520
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a period for screening tests to be economically viable. In this study, candidate timber species were selected for testing in the sea on the basi...

Leaching from CCA-treated wood submerged in seawater: Effect of high loadings, and a comparison between laboratory and marine conditions
1996 - IRG/WP 96-50080
This study of leaching examined the following variables: CCA loading; marine versus laboratory exposure and length of submergence. Blocks of Pinus sylvestris were treated to a range of nominal retentions from 15 to 50 kg/m³. Each block was then divided into three cubes and all transverse faces were sealed. All cubes were allowed to fix at ambient temperature for a minimum of one week. One set of ...

Fouling assemblage development on copper-chromium-arsenic-treated timber submerged in European waters
2002 - IRG/WP 02-50181
The effect of the anti-marine-borer timber preservative CCA on community development of non-target marine fouling animals was investigated. Panels of Scots pine treated to target retentions of 12, 24 and 48 kg CCA per m3 of wood, plus untreated controls were submerged at seven coastal sites (Portsmouth, UK; La Tremblade (2 sites), France; Ria Formosa, Portugal; Sagres, Portugal; Kristineberg, Swed...

Marine exposure assessment in southern Portugal of the natural resistance of a number of lesser known species of tropical hardwoods to teredinid and limnoriid borers
2007 - IRG/WP 07-10614
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment.

Assessment of the marine borer resistance and abrasion resistance of lesser known hardwood timber species for use in marine construction
2010 - IRG/WP 10-10711
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a period for screening tests to be economically viable. In this study, candidate timber species were selected for testing both in the laboratory...
