Abstract
The scarcity of timber and its rising costs necessitates the use of chemical preservative
treated wood for aquatic use. Preservative treated wood contains components that may be
harmful to the environment. The wood treated with the most common preservative,
Chromated Copper Arsenate (CCA), may form a significant source of metals in the aquatic
environment. The studies on the factors affecting the leaching rates like pH, salinity, and
temperature of the leaching media, the block size and the preservative treatment conditions
are reviewed. Recent studies have generated conflicting data in this regard and Field studies
in this direction are also found to be few. This communication highlights the need for further
research in this field.
