Effective and safe composting of chlorophenol-contaminated soil in pilot scale

Article Abstract:

A study aimed at exploring better ways to efectively and safely bioremediate chlorophenol-contaminated soil in pilot scale is presented. Chlorophenols, which are often used as wood preservatives, do not completely mineralize and pose environmental and health risks. The study utilized four compost piles of chlorophenol-contaminated soil to determine chlorophenol degradation in each pile upon inoculation of straw compost and remediated soil. It is found out after 6 months of composting that the inocula barely affected the fast and efficient biodegradation of the chlorophenols.

Kinetics and potential significance of polycyclic aromatic hydrocarbon desorption from creosote-treated wood

Article Abstract:

The kinetics and potential significance of polycyclic aromatic hydrocarbons (PAHs) desorption from creosote-treated wood is investigated. Results revealed that the rates of desorption of five PAHs namely acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene followed first-order kinetics and were higher at 30 than 4 degrees Celsius. The volatilization rate remained constant even after 7 weeks when the kinetics were allowed to remain at 4 degrees Celsius.

Fate and toxicity of chlorophenols, polychlorinated dibenzo-p-dioxins, and dibenzofurans during composting of contaminated sawmill soil

Article Abstract:

The composting of sawmill soil contaminated by chlorophenols is an effective bioremediation technique that does not result in the creation of harmful metabolites. However, the procedure does not effectively reduce the amounts of dibenzofurans and polychlorinated dibenzo-p-dioxins and thus composting would not by itself be an effective remediation technique.
