“…According to Fang et al (2003), high concentrations of Fe, particularly in PM 2.5 , were associated with exhaust emissions, especially from gasoline-and diesel-fuelled road vehicles. Soil dust has been recognized as one of major sources of Fe (Han et al 2014). This may explain the higher concentration of Fe in the rural area (S3).…”

This study determined the source contribution of PM2.5 (particulate matter <2.5 μm) in air at three locations on the Malaysian Peninsula. PM2.5 samples were collected using a high volume sampler equipped with quartz filters. Ion chromatography was used to determine the ionic composition of the samples and inductively coupled plasma mass spectrometry was used to determine the concentrations of heavy metals. Principal component analysis with multilinear regressions were used to identify the possible sources of PM2.5. The range of PM2.5 was between 10 ± 3 and 30 ± 7 µg m(-3). Sulfate (SO4 (2-)) was the major ionic compound detected and zinc was found to dominate the heavy metals. Source apportionment analysis revealed that motor vehicle and soil dust dominated the composition of PM2.5 in the urban area. Domestic waste combustion dominated in the suburban area, while biomass burning dominated in the rural area.

Our study highlights that fungal biosorption capacity is highly dependent on the sampling area (roadside vs jungle) with roadside fungal strains showing significantly higher copper (Cu) biosorption capacities using living biomass compared to fungal strains originating from plants collected in virgin jungle (P < 0·05). It also highlights that different biosorption mechanisms (alive - metabolic dependent and dead biomass - metabolic independent) result in different amounts of Cu being removed from the solutions. The living biomass possessed a better biosorption capacity than the dead biomass (P < 0·05).

“…Research has shown that adverse health effects associated with proximity to roads are strongly related to tailpipe emissions [6][7]. The most common heavy metals introduced to environments in the proximity of traffic activity and road construction are lead (Pb), copper (Cu), cadmium (Cd), zinc (Zn), chromium (Cr), and nickel (Ni) [8][9][10][11]. The use of leaded petroleum is the primary source of Pb emissions (before unleaded gasoline entered circulation in China in 2000) [12].…”

Heavy metal contaminations were assessed through a detailed soil survey in roadside soils along the Shenyang-Dalian Highway of Liaoning Province, China. Pb, Cu, Cd, Ni, and Zn were analyzed using atomic absorption spectrophotometry. The average concentrations of Pb, Cu, Cd, Ni, and Zn in roadside soils were 43.8, 26.5, 0.119, 32.1, and 71.3 mg/kg, respectively, and all concentrations exceeded the background values. Different heavy metal distribution patterns were found under different land use types. In farmland, a peak metal concentration occurred 25 m from the roadside soil, while in the forest and orchard soil all heavy metals decreased with distance from the roadside, which conformed to the exponential model. Heavy metal concentrations were markedly higher than those measured in 1999 and 2007, except for Cd. Concentrations in soils along the Shenyang-Dalian Highway were medium or low in comparison with roadside soils in other cities around the world. Overall, this assessment illustrates that heavy metal pollution in these soils is generally low, and we recommend that more attention should be given to Pb contamination in roadside soils along the Shenyang-Dalian Highway.
