Evaluation of pressure treated wood impact on landfill waste decomposition using a methane yield assay
چکیده انگلیسی

Research was conducted to investigate the potential impact of CCA-treated wood and other arsenic-free Cu-based preservative-treated wood on microorganisms, involved in the anaerobic decomposition of waste in landfills. Wood preservatives used included alkaline copper quat (ACQ), copper citrate (CC), copper boron azole (CBA), copper dimethyldithiocarbamate (CDDC), and chromated copper arsenate (CCA). The biochemical methane potential (BMP) assay was used to estimate the possible impacts. The methane yields of mixtures of preservative-treated wood or untreated wood with cellulose (group 1) and these wood samples only (group 2) were determined. An analysis of variance (ANOVA) test found that there were no significant differences among methane yields results in either group 1 or group 2, at the 0.05 level of significance. The results indicate that under the conditions tested, none of the treated wood products evaluated were toxic to the methane-producing organisms. At the end of the assays, test bottle contents were analyzed for Cu, Cr, and As. When the fraction of each metal in the solution (relative to original metal in the wood, leachability %) was examined, As was present at the great extent. The leachability of As was in the range from 15.1% to 21.7% while relatively low leachability (1.7–7.6%) of Cu was observed.
