Total PAH concentration of soil before and after bioremediation. (a) Soils from five consecutive sampling times during 7-d cycle in the bioreactor treatment. (b) Soils from both the control column and biostimulated column at four sampling points along each column after 2.5-year column treatment. Values are mean ± SD of triplicates. BFS: untreated bioreactor feed soil; BTS: bioreactor treated soil; CPS: untreated column packing soil; CTR: control-column treated soil; BIO: biostimulated-column treated soil.
