	%X Urban road dust comprises of a range of potentially 
toxic metal elements and plays a critical role in degrading urban 
receiving water quality. Hence, assessing the metal composition and 
concentration in urban road dust is a high priority. This study 
investigated the variability of metal composition and concentrations 
in road dust in 4 different urban land uses in Gold Coast, Australia. 
Samples from 16 road sites were collected and tested for selected 12 
metal species. The data set was analyzed using both univariate and 
multivariate techniques. Outcomes of the data analysis revealed that 
the metal concentrations inroad dust differs considerably within and 
between different land uses. Iron, aluminum, magnesium and zinc are 
the most abundant in urban land uses. It was also noted that metal 
species such as titanium, nickel, copper and zinc have the highest 
concentrations in industrial land use. The study outcomes revealed 
that soil and traffic related sources as key sources of metals deposited 
on road surfaces.
