Abstract

A sequential digest was used to examine the speciation of particulate-associated heavy metal pollutants in a holistic approach to the study of the movement of sediment within the urban environment. Sediments were classified according to whether they mainly acted as sources, were mostly transported, or had become deposited and were fractionated into two particle sizes to reflect sediment deposited in lakes (< 63 μm) and transported in rivers (< 2 mm). Results showed that the two particle size fractions yielded the same data, but that trends were found in terms of dominant heavy metal species as the sediment moved through the source-transport-deposit cascade. Whilst the results highlighted the complexity of the urban environment, a sequential digestion of the samples enabled comments to be made in terms of risk which could subsequently feed in to a management strategy for polluted urban sediments.
