Dissipation of polycyclic aromatic hydrocarbons from soil added with manure or vermicompost
چکیده انگلیسی

The dissipation of three PAHs, i.e., 500 mg phenanthrene kg−1 soil, 350 mg anthracene kg−1 soil and 150 mg benzo(a)pyrene kg−1 soil, was investigated in soil from Acolman (México) added with cow manure or vermicompost while production of CO2 and inorganic N was monitored. At day 0, recovery of added phenanthrene was 95%, anthracene 96% and benzo(a)pyrene 100% in sterilized soil and concentrations did not change significantly in sterilized soil over time. Application of organic material did not affect the concentration of phenanthrene and anthracene, which decreased sharply in the unsterilized soil in the first weeks of the incubation. Less than 3% of the added phenanthrene was detected after 100 days and less than 8.5% of the added anthracene (mean of the two experiments). The decrease in concentration of benzo(a)pyrene (BaP) was not fast as that of phenathrene and anthracene, and 22% was extractable from soil still after 100 days. It was concluded that addition of farm yard manure (FYM) and vermicompost only had an effect on the initial dissipation of phenanthrene, anthracene and benzo(a)pyrene in soil of Acolman.
