It was not clear whether this was due to a higher anthracene bioavailability or an increased microbial degradation in the topsoil layer. Therefore, an arable soil was contaminated with 500mg anthracene kg−1 dry soil, and its removal was monitored with an exhaustive technique and with n-butanol to determine its bioavailability in three layers. Additionally, part of the contaminated soil was stored aerobically for 112days (considered the aged soil), and the anthracene was monitored thereafter. After 112days, 360mg anthracene kg−1 was removed from the soil, but its dissipation was not affected by the layer, depth, and fluctuations in water content or the interaction between. In the aged soil stored for 112days, only 170mg anthracene kg−1 was removed. In the subsequent incubation of the aged soil, 273mg anthracene kg−1 was removed within 28days, and after 112days, no contaminant was detectable in the soil. An additional experiment confirmed the hypothesis that simply mixing the soil accelerated the removal of anthracene. Mixing the soil every 7days removed all anthracene from the soil within 28days, while in the undisturbed soil, 301mg anthracene kg−1 was still extractable. It can be concluded that mixing the soil accelerated the removal of anthracene, but fluctuations in water content did not. The anthracene extracted with n-butanol was not related to the amount removed and is thus not a good indicator of bioavailability of anthracene in soil.
