TI  - Analysis of heavy metals in road-deposited sediments.
PG  - 270-8
AB  - Road-deposited sediments were analysed for heavy metal concentrations at three 
      different landuses (residential, industrial, commercial) in Queensland State, 
      Australia. The sediments were collected using a domestic vacuum cleaner which was 
      proven to be highly efficient in collecting sub-micron particles. Five particle 
      sizes were analysed separately for eight heavy metal elements (Zn, Fe, Pb, Cd, 
      Cu, Cr, Al and Mn). At all sites, the maximum concentration of the heavy metals 
      occurred in the 0.45-75 microm particle size range, which conventional street 
      cleaning services do not remove efficiently. Multicriteria decision making 
      methods (MCDM), PROMETHEE and GAIA, were employed in the data analysis. 
      PROMETHEE, a non-parametric ranking analysis procedure, was used to rank the 
      metal contents of the sediments sampled at each site. The most polluted site and 
      particle size range were the industrial site and the 0.45-75 microm range, 
      respectively. Although the industrial site displayed the highest metal 
      concentrations, the highest heavy metal loading coincided with the highest 
      sediment load, which occurred at the commercial site. GAIA, a special form of 
      principal component analysis, was applied to determine correlations between the 
      heavy metals and particle size ranges and also to assess possible correlation 
      with total organic carbon (TOC). The GAIA-planes revealed that irrespective of 
      the site, most of the heavy metals are adsorbed to sediments below 150 microm. A 
      weak correlation was found between Zn, Mn and TOC at the commercial site. This 
      could lead to higher bioavailability of these metals through complexation 
      reactions with the organic species in the sediments.
