Accelerated laboratory soil contact decay test using soil amended with composted wood
2004 - IRG/WP 04-20284
The effect of amending soil with wood compost on the decay rate of wood wafers in contact with the unsterile soil, as measured by radial compression strength loss, was explored. It was found that the addition of composted wood to the soil significantly increased the wood decay rate. The reason for this acceleration in wood decay is not entirely clear, but appears to be at least partially associate...

Remediation of Pentachlorophenol (PCP) in Biodiesel versus Diesel Carriers
2011 - IRG/WP 11-50279
Biodiesel is believed to be more environmentally friendly than petroleum based diesel when used as a carrier for impregnation of PCP into wood products for protecting wood from decay. A six month study was conducted to evaluate the remediation of PCP in biodiesel versus diesel in soil. Different percentages of biodiesel, diesel and PCP were mixed with clean soil from a forested site and tested. Sa...

Effect of Biodiesel on the Efficacy of Pentachlorophenol Treated Wood
2012 - IRG/WP 12-30584
Pentachlorophenol (PCP) is widely used as a wood preservative for utility poles and other wood products. Recently, it has been proposed that a modified PCP carrier system based on a diesel/biodiesel mixture should be used in place of the conventional diesel/KB3 carrier, but there is some question as to whether or not this modified carrier system can provide the same service life for wood products ...

Leaching Potential of selected Mississippi Soils Contaminated with Pentachlorophenol (PCP) and Chromated Copper Arsenic (CCA)
2013 - IRG/WP 13-50293
Desorption of pentachlorophenol (PCP), and chromated copper arsenic (CCA) from five Mississippi soil regions was studied. The soils tested were Blackland Prairie (Dorman), the Interior Flatwoods (Winston), the Delta, the Coastal Plains (Wiggins) and the Loess soil (Raymond). Soils were contaminated with 500 ppm and 1000ppm PCP and 1000 ppm for CCA respectively. Toxicity Characteristic Leaching Pro...

Hydroponic Phytoremediation of Chromated Copper Arsenate (CCA) and Copper Contaminated Water
2014 - IRG/WP 14-50304
The removal of selected metals by duckweed (Lemna minor) and parrotfeather (Myriophyllum aquaticum) from a simulated aqueous environment contaminated with Chromated Copper Arsenate (CCA) and copper sulfate was studied in a controlled laboratory experiment. The duckweed and parrotfeather’s tissues were analyzed to evaluate the removal of copper (Cu), chromium (Cr), and arsenic (As) from CCA cont...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...

Efficacy of lignocellulosic materials for Removal of Cation and Anions from Industrial and Urban Wastewater
2016 - IRG/WP 16-50321
The adsorption of Ca, Zn, Na, Cd (II), Cr (III) and No3 ions from industrial and urban wastewater and aqueous solutions by poplar (Populusnigra) sawdust, cotton linter, zeolite and expanded perlite were examined on the basis of a batch adsorption technique. The results revealed that application of sawdust, cotton linter, perlite and zeolite are effective in improving elimination of Ca, Zn, Na ions...
