Change in soil's metal carrying capacity as a result of Urban sludge addition

摘要

The present work investigates the behaviour of heavy metals accumulating in soils treated with urban sludge with respect to untreated soils. Metal sorption during transport in the soils was evaluated by means of breakthrough curves obtained via the soil column leaching test and the results of laboratory experiments were compared with those of field experiments carried out on the same soil treated in situ with urban sludge.
