Abstract:Seventeen compounds of polycyclic aromatic hydrocarbons (PAHs) in Ipomoea aquatic potted in paddy soil fertilized with municipal sludges and chemical fertilizer in greenhouse were determined by GC/MS. The results showed that the total contents of PAHs ( ∑ PAHs) in Ipomoea aquatic (aboveground) grown in varied treatments ranged from 0.414mg/kg to 5.404mg/kg, decreased in the order of Foshan sludge + fertilizer (5.404mg/kg)>Guangzhou sludge + fertilizer (2.291mg/kg)>fertilizer (1.961mg/kg)>Guangzhou sludge (1...
