Title

LEACHING CHARACTERISTICS OF PHENANTHRENE AND PYRENE IN BIOCHAR-AMENDED CONTAMINATED SOIL

Pages

  573-581

Abstract

 Contamination of SOIL with persistent organic contaminants has been of great concerndue to their long-term effects in the environment. Polycyclic aromatic hydrocarbons(PAHs) are a well-known group of organic contaminants characterized bytheir resistance to biodegradation and high hydrophobicity. Mobilization and migrationof PAH compounds in hydrocarbon-contaminated site may endangergroundwater resources. The main objective of this study was to investigate theinfluence of pulverized BIOCHAR on IMMOBILIZATION and release characteristics ofmodel PAHs. Column leaching test was used to simulate leaching of PAH compoundsfrom contaminated solid phase towards aqueous phase. Results showedstrong sorption of both studied PAHs i.e. PHENANTHRENE and PYRENE to SOIL particles,however, at the end of the experiment 5.32% and 0.99% of the initial solid phasecontent of, respectively, PHENANTHRENE and PYRENE released into water in unamendedsoil. Application of pulverized BIOCHAR could finally reduce mobilization and cumulativerelease of the above-mentioned PAH compounds significantly. Similar trendwas also obtained for sum 16 US EPA PAHs. Variation of pH during the leachingprocess and its contribution to mobilization and release of selected PAH compounds,which has scarcely studied previously, were also addressed. Results indicatedthat pulverized BIOCHAR as a cost-effective alternative to other carbon-richamendments e.g. activated carbon can be effectively employed for site remediationpurposes to reduce mobilization of PAHs in SOIL.
