| Abstract | A six month study evaluated the effects of amendments to soil contaminated with polychlorinated biphenyls (PCBs) and petroleum hydrocarbons. The objective was to determine which amendments could enhance biodegradation of Aroclors 1242, 1248, and 1260 and reduce the concentration of total petroleum hydrocarbons (TPH). The amendments added were chicken manure, chicken manure plus 1,000 ppm biphenyl, kenaf, and kenaf plus white rot fungus (Phanerochaete chrysosporium). All treatments and control were replicated three times. Contaminated soil and amendments were place in 1.5 L amber dishes and kept in an environmental chamber. Moisture was adjusted every two days. Samples were collected at 45 day intervals for biological and chemical analysis. PCB concentrations for Aroclors 1242 and 1248 were significantly reduced in all treatments and the control by day 180. Only the kenaf plus white rot fungus treatment showed a significant decrease in Aroclor 1260 concentration from days 0 to 90, but increased by day 180. All treatments showed a significant reduction of TPH by the end of the study. |
