Abstract
The performance of Bombax ceiba treated with selected inorganic preservatives was assessed in marine exposures over a 44-month period in southern India. Panels treated to high retentions with ammoniacal copper zinc arsenate (ACZA) provided the best protection, followed by the higher chromated copper arsenate (CCA) retention. Pholads tended to be the dominant organisms on ACZA- and CCA-treated wood. Teredinids were more prevalent on ammoniacal copper citrate (CC) or ammoniacal copper quaternary (ACQ) treatments. The potential for using these preservatives to extend service life of this species in tropical waters was discussed.
