Abstract

Abstract Chlorophenols, like many other synthetic compounds,
are persistent problem in industrial areas. These
compounds are easily degraded in certain natural environments
where the top soil is organic. Some studies suggest
that mineral soil contaminated with organic compounds is
rapidly remediated if it is mixed with organic soil. We
hypothesized that organic soil with a high degradation capacity
even on top of the contaminated mineral soil enhances
degradation of recalcitrant chlorophenols in the mineral
soil below. We first compared chlorophenol degradation in
different soils by spiking pristine and pentachlorophenolcontaminated
soils with 2,4,6-trichlorophenol in 10-L buckets.
In other experiments, we covered contaminated mineral
soil with organic pine forest soil. We also monitored in situ
degradation on an old sawmill site where mineral soil was
either left intact or covered with organic pine forest soil.
2,4,6-Trichlorophenol was rapidly degraded in organic pine
forest soil, but the degradation was slower in other soils. If a
thin layer of the pine forest humus was added on top of
mineral sawmill soil, the original chlorophenol concentrations
(high, ca. 70 μg g−1, or moderate, ca. 20 μg g−1) in
sawmill soil decreased by >40 % in 24 days. No degradation
was noticed if the mineral soil was kept bare or if the
covering humus soil layer was sterilized beforehand. Our
results suggest that covering mineral soil with an organic
soil layer is an efficient way to remediate recalcitrant chlorophenol
contamination in mineral soils. The results of the
field experiment are promising.
