The ability of white-rot fungus to deplete pentachlorophenol (PCP) and polynuclear aromatic hydrocarbons (PAHs) from soil, which was contaminated with commercial wood preservatives, was demonstrated in a field study. Inoculation of soil containing 968 {micro}g of PCP g{sup {minus}1} and 1,420 {micro}g of total PAHs g{sup {minus}1} with Phanerochaete sordida resulted in an overall decrease of 71% of PCP and 59% of total PAHs in the soil in 20 weeks. Over the same period, in soil containing 855 {micro}g of PCP g{sup {minus}1} and 1,050 {micro}g of total PAHs g{sup {minus}1} which was amended with sterile spawn (i.e., not containing P. sordida) material, an overall decrease of 69% of PCP and 66% of total PAHs was observed. And, in soil containing 746 {micro}g of PCP g{sup {minus}1} and 1,100 {micro}g of total PAHs g{sup {minus}1}, which was neither inoculated with P. sordida nor amended with the sterile spawn material, an overall decrease of 14% of PCP and 65% of total PAHs was observed. Results indicate that the degradation rates and percent reductions of PCP and PAHs in the inoculated and the amended soils were statistically the same. Percent reductions and degradation rates of PCP and the 4- and 5-ring PAHs in the inoculated and amended soils were significantly higher than in the nonamended soil. In contrast, reductions and degradation rates of 2- and 3-ring PAHs in the nonamended soil were significantly higher than in either the inoculated or amended soils. Overall reductions in total PAHs in the three soils were statistically identical.
