| 1 | Bioremediation of Soil Contaminated with Petroleum Using Forced-Aeration Composting显示文摘Laboratory simulation studies and a composting pilot study were conducted to evaluate the capacityof three strains of fungi, indigenous fungus Fusarium sp. and Phanerochaete chrysosporium and CoriolusVersicolor, to remediate petroleum- contaminated soils. In laboratory, the fungi were inoculated into a liquidculture medium and the petroleum-contaminated soil samples for incubation of 40 and 50 days 5 respectively.In the 200-day pilot study, nutrient contents and moisture were adjusted and maintained under aerobiccondition in composting units using concrete container (118.5 cm × 65.5 cm × 12.5 cm) designed speciallyfor this study. The laboratory simulation results showed that all the three fungi were effective in degradingpetroleum in the liquid culture medium and in the soil. At the end of both the laboratory incubations, thedegradation rates by Phanerochaete chrysosporium were the highest, reaching 66% after incubation in liquidculture for 50 days.

| 2 | Alleviation of Soil Acidity and Aluminium Phytotoxicityin Acid Soils by Using Alkaline-Stabilised Biosolids显示文摘A pot experiment was catried out to study alleviation of soil acidity and Al toxicity by applying analkaline-stabilised sewage sludge product (biosolids) to an acid clay sandy loam (pH 5.7) and a strongly acidsandy loam (pH 4.5). Barley (Hondeum vulgare L. cv. Forrester) was used as a test crop and was grownin the sewage sludge-amended (33.5 t sludge DM ha-1) and unamended soils. The results showed that thealka1ine biosloids increased soil pH from 5.7 to 6.9 for the clay sandy loam and from 4.5 to 6.0 for the sandyloam. The sludge product decreased KCl-extractable Al from 0.1 to 0.0 cmol kg-1 for the former soil andfrom 4.0 to 0.1 cmol kg-1 for the latter soil. As a result, barley plants grew much better and grain yieldincreased greatly in the amended treatments compared with the unamended controls. These observationsindicate that alkaline-stabilised biosolids can be used as a liming material for remedying Al phytotoxicity instrongly acid soils by increasing soil pH and lowering | LUOYONGMING P.CHRISTIE | 2002 | Pedosphere2002，12，2： | 6 |
| 3 | Effect of Alkaline-Stabilised Sewage Sludge on Extractable Organic Carbon and Copper in Soils显示文摘An incubation experiment was conducted to evaluate the potential for water contamination with sludge-derived organic substances and copper following land application of alkaline-stabilised sewage sludge. Twocontrasting sludge-amended soils were studied. Both soils were previously treated with urban and ruralalkaline biosolids separately at sludge application rates of 0, 30 and 120 t ha-1 fresh product. The air-driedsoil/sludge mixtures were wetted with distilled water, maintained at 40 % of water-holding capacity andequilibrated for three weeks at 4 ℃ before extraction. Subsamples were extracted with either distilled wateror 0.5 mol L-1 K2SO4 solution. The concentrations of organic C in the aqueous and chemical extractswere determined directly with a total organic carbon (TOC) analyser. The concentrations of Cu in the twoextracts were also determined by atomic absorption spectrophotometry The relationship between the twoextractable organic C fractions was examined, together with | LUOYONGMING P.CHRISTIE | 2002 | Pedosphere2002，12，2： | 4 |

| 5 | Extractability of Cu in Alkaline Biosolids-Amended Soilsas Influenced by γ-Irradiation显示文摘An incubation experiment was conducted to investigate the microbial biomass associated Cu in fourcontrasting soils to which an alkaline stabilised sewage sludge cake was applied. The organisms of sludge-amended and control soils were killed using ry-irradiation technique, and the aqueous and acid-extractable Cuconcentrations were determined. Addition of the sludge product increased significantly the concentration ofboth the aqueous and dilute HOAc-extractable Cu in all the irradiated soils compared to the non-sterilisedsludge/soil mixtures, but the increase was more pronounced in the dilute acid-extractable Cu, indicating thatthe Cu rendered extractable in water and dilute acetic acid by 7-irradiation existed in the both soil liquidand solid phases. The additional increase in extractable Cu following the biocidal treatment is likely to bedue to release of Cu from the same fraction of soil microbial biomass. | LUOYONGMING P.CHRISTIE | 2002 | Pedosphere2002，12，2： | 0 |
