Release of copper-amended particles from micronized copper-pressure-treated wood during mechanical abrasion
BACKGROUND We investigated the particles released due to abrasion of wood surfaces pressure-treated with micronized copper azole (MCA) wood preservative and we gathered preliminary data on its in vitro cytotoxicity for lung cells. The data were compared with particles released after abrasion of untreated, water (0% MCA)-pressure-treated, chromated copper (CC)-pressure-treated wood, and varnishe...
متن کاملPenetration and Effectiveness of Micronized Copper in Refractory Wood Species
The North American wood decking market mostly relies on easily treatable Southern yellow pine (SYP), which is being impregnated with micronized copper (MC) wood preservatives since 2006. These formulations are composed of copper (Cu) carbonate particles (CuCO3·Cu(OH)2), with sizes ranging from 1 nm to 250 μm, according to manufacturers. MC-treated SYP wood is protected against decay by solubili...
متن کاملRemoval of nano- and micronized-copper from treated wood by chelating agents
Micronized and nano-copper (Cu)-based and arsenic and chromium-free systems have received much attention for wood protection in recent years. Because they have different fixation, and micro-distribution properties, such copper systems may be more or less subject to release using known remediation methods than soluble forms of Cu. This study evaluated Cu recovery from wood treated with micronize...
متن کاملHigh-density Polyethylene-based Composites with Pressure-treated Wood Fibers
High-Density Polyethylene (HDPE)-based composites with alkaline copper quaternary (ACQ)and micronized copper quaternary (MCQ)treated wood fibers were manufactured through injection molding. The mechanical properties, water absorption, and biological resistance properties of the fabricated composites with different coupling treatments were investigated. Composites with ACQand MCQ-treated wood ha...
متن کاملReview of Thermochemical Conversion Processes as Disposal Technologies for Chromated Copper Arsenate (cca) Treated Wood Waste
Several alternative methods for the disposal of chromated copper arsenate (CCA) treated wood waste have been studied in the literature, and these methods are reviewed and compared in this paper. Extraction experiments have been carried out on CCA treated wood and evaluated as a method to recover the metal compounds into either fresh wood preservatives or other useful industrial materials. Recyc...
