- Abstract
- The magnitude and ecological relevance of metal pollution of the middle Po river deriving from the River Lambro tributary was investigated
by applying different (complementary) sediment quality assessment approaches: (1) comparisons of concentrations with regional
reference data, and (2) comparisons with consensus-based sediment quality guidelines (SQGs), as well as by investigations of the partitioning
patterns of target heavy metals (Cd, Cu, Ni, Pb, Zn). Total metal concentrations in the surficial sediments revealed significant
pollution inputs on the whole river stretch investigated, with a distinct peak at the inlet of the River Lambro. Based on the geoaccumulation
index of target heavy metals, the middle reach of River Po has to be considered as moderately polluted with Cd (1 < mean
Igeo < 2). At the Lambro inlet the surficial sediments have to be considered as moderately to strongly polluted with Cd (2 < mean
Igeo < 3) and moderately polluted with Cu, Pb and Zn (1 < mean Igeo < 2 for each). Sediment-bound Cd, and Zn were found to be predominantly
associated with the exchangeable phase of the sediment (33-58% and 25-43%, respectively), whereas Cu, Ni and Pb showed
the strongest association with the Fe/Mn oxides (34-64%, 34-46% and 29-45%, respectively). Based on the consensus-based SQGs, most
samples (50-63%) had contamination characteristics associated with moderate probabilities (30-52%) of acute toxicity for all investigated
metals, while Cu and Zn in ?13% of samples revealed contamination characteristics associated with high probabilities (74-
85%) of toxicity. (literal)
