Sewage sludge-amended soils containing indigenous and spiked petroleum
hydrocarbons (gas-oil and lubricating oil) were monitored for aliphat
ic hydrocarbons weathering. Results indicated that n-alkanes were lost
by abiotic and biotic processes, the former being more important for
the short-chain alkanes. Their half-lives were from 2.7 to 5.9 days, d
epending on the initial concentration.
