Description: The purpose of this chapter is to make the reader aware of how choices in study parameters may influence the outcome of treated-wood environmental impact evaluations. Evaluation of the leaching and environmental accumulation of preservatives from treated wood is a complex process. and many factors can influence the results of such studies. In laboratory studies, the effects of specimen dimensions, wood species, treatment practices, fixation and leaching exposure must be considered. Evaluation of in-service structures introduces additional variability, with factors such as age of the structure, type of exposure, construction and maintenance practices and site characteristics. There is no perfect study design to account for all of these factors. and in many cases, they cannot be controlled. However, researchers should be aware of these factors, and the relative importance of these sources of variability to a particular study should be considered when interpreting and reporting study results.
