Mobility of Soil Contaminants in an Ecosystem of Trees Growing on Dredged Material - The Broekpolder (Rotterdam, The Netherlands).
Abstract
In 1987 an experimental study was started of the bioavailability of some contaminants in ecosystems growing on dredged material in a dumping site. Standard bioassays (earthworm bioassay with Eisenia foetida and plant bioassay with Cyperus esculentus) were carried out on substrates taken from an 25-year-old disposal site for dredged material, near Rotterdam, on which trees were planted some 15 years ago. Both the anoxic soil layer (resembling an unchanged dredged mud) and the humus-rich, upper soil layer (resembling mature dredged mud) were tested. Part of the Broekpolder was originally selected to see whether trees will grow on dredged material, and three species (Populus, Quercus and Acer) were planted separately in identical plots. Their impact on the mobility of contaminants in the mature humic soil layer is the focal point of this study. Keywords: Netherlands.
