An experimental study of the environmental impacts of CCA-treated wood waste land application
… arsenate (CCA) has been the most commonly used wood preservative in the UK; up until its partial ban in 2004. The preservative prolongs the service life of wood by 20-50 years by making it resistant to biological attack. As such, in-service CCA treated wood is expected to be a major component of …
