Abstract
Road-deposited sediment (RDS) has become an increasingly important medium for analysing anthropogenic urban metal accumulation. This study aims to understand the environmental risk of RDS, through its spatial and temporal variability, across the Manchester urban conurbation. Using an acid digest and spectrometry, the concentrations of iron (Fe), copper (Cu), manganese (Mn), zinc (Zn) and lead (Pb) in the RDS were determined. The geochemical maps presented show a high degree of spatial variability; however, all five metals display high concentrations within Manchester City centre and low concentrations in Salford Quays. A comparison with historical data finds that potentially toxic element (PTE) concentrations have predominantly increased over time. Pb was the only PTE with a lower average concentration since a 2006 study, albeit still high due to its persistent nature.
