“…To date, much research has been conducted on the physical, mechanical, shrinking and swelling properties of various impregnated wood species. Examples of these species are European beech, pine, spruce, Scots pine, yellow poplar, and red oak treated with waterborne preservatives such as chromated copper arsenate (CCA), ammoniacal copper arsenate (ACA), ammoniacal copper zinc arsenate (ACZA), and alkaline copper quaternary (ACQ) compounds (Winandy, 1995); pine treated with linseed oil (Megnis et al, 2002); yellow pine treated with CCA, ACQ-1900, ACQ-2200, Tanalith-E 3491, and Wolmanit CX-8 (Yildiz et al, 2004); oriental beech, oak, Scots pine, oriental spruce, and Uludag fir treated with Imersol-Aqua (Ors et al, 2005); pine and American beech treated with copper chloride, sodium borate, and phenol-formaldehyde resinpyrolytic oil (Mourant et al, 2007); jack pine and sugar maple treated with copper chloride, copper chloride-sodium borate mixture, and phenol formaldehyde-pyrolytic oil resins (Mourant et al, 2008); beech and pine treated with aqueous solution of borates (Simsek et al, 2010); rowan treated with Tanalith-E, Vacsol Azure, Imersol-Aqua, borax, and boric acid (Keskin et al, 2013); fir treated with citric acid (Ville et al, 2014); oriental beech treated with Turkish sweetgum balsam as an aromatic resinous wood preservative (Degirmentepe et al, 2015); and beech, walnut, poplar, ash, and pine treated with Tanalith-E (Keskin and Daglioglu, 2016); shrinking and swelling minimization of wood treated with the synthetic resin-forming materials (Stamm and Seborg, 1936); beech wood impregnated with NH3 (Bariska, 1975); Corsican pine wood treated with ammonia (Coles and Walker, 1978); swelling of wood in liquid ammonia (Stamm, 1955). Some of the wood preservatives mentioned above are now prohibited in several countries, and are being used less frequently in other countries due to their negative impacts to the environment.…”
