Summary: | In this work we investigated the phytoremediation of a polycyclic aromatic hydrocarbons (PAHs) contaminated soil. The soil collected from a PAH contaminated area has been put in microcosms and Medicago sativa has been sown. Results showed significant differences between vegetated and non-vegetated pots. The concentration of some PAHs decreased as function of time. In non-vegetated pots, total PAHs concentration was 1,308 mg/kg; after three months of Medicago sativa growing, PAHs concentration decreased to 907 mg/kg. The percentage of degradation was more than 50%for indeno(1,2,3-c,d)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene; between 20 and 30% for fluorene, benzoanthracene, crysene, benzo(b+k)fluorantene, benzopyrene and dibenzo(a,i)pyrene
[In questo lavoro abbiamo studiato la fitodepurazione di un terreno contaminato da idrocarburi policiclici aromatici (IPA). Il terreno, raccolto da un'area contaminata da IPA, è stato posto in contenitori ed è stata seminata Medicago sativa. I risultati hanno evidenziato differenze significative fra i vasi con e senza piante. La concentrazione di alcuni IPA è diminuita in funzione del tempo. Nei vasi senza vegetazione la concentrazione totale di IPA era di 1.308 mg/kg; dopo tre mesi di coltivazione di Medicago sativa, la stessa è diminuita a 907 mg/kg. La percentuale di degradazione è stata superiore al 50% per indeno(1,2,3-c,d)pirene, dibenzo(a,h)antracene, benzo(g,h,i)perilene; fra 20 e 30% per fluorene, benzoantracene, crisene, benzo(b+k)fluorantene, benzopirene e dibenzo(a,i)pirene] |
