Trial site, United States
US wood-preservative site, PCP-contaminated soil (Lamar and Dietrich field study)
Soil contaminated with a commercial wood preservative, at 250–400 µg/g of pentachlorophenol and very little organic matter. The abstract does not give the place: the map point is purely indicative (centre of the United States) and must be corrected from the full text.

Lamar and Dietrich inoculated the soil in the field with two white-rot fungi, adding peat as a carbon source, at temperatures below the fungi's optimum and without mineral nutrients.
Outcome Extractable PCP fell by 88–91% in 6.5 weeks. But 8–13% of the decrease was methylation to pentachloroanisole and most of the PCP turned out to be converted into non-extractable soil-bound products, not mineralised. The authors themselves write that the nature, stability and toxicity of those products must be clarified before the method can be considered viable.
