“…These elevated PTE levels have been found to be due to geogenic (Wragg 2005) and anthropogenic (Dao et al 2012) sources of contamination or a combination of both (Facchinelli et al 2001;Zhang et al 2008;Rodrigues et al 2006;Mostert et al 2012). Elevated nickel (Ni) and chromium (Cr) from geogenic sources have been identified worldwide (Quantin et al 2008;Megremi 2010;Kierczak et al 2007;Johnson et al 2012;Barsby et al 2012).…”

Potentially toxic elements (PTEs) including nickel and chromium are often present in soils overlying basalt at concentrations above regulatory guidance values due to the presence of these elements in underlying geology. Oral bioaccessibility testing allows the risk posed by PTEs to human health to be assessed, however bioaccessibility is controlled by factors including mineralogy, particle size, solid phase speciation and encapsulation. X-ray diffraction (XRD) was used to characterise the mineralogy of 12 soil samples overlying Palaeogene basalt lavas in Northern Ireland and non specific sequential extraction coupled with chemometric analysis was used to determine the distribution of elements amongst soil components in 3 of these samples. The data obtained were related to total concentration and oral bioaccessible concentration to determine whether a relationship exists between the overall concentrations of PTEs, their bioaccessibility and the soils mineralogy and geochemistry.Gastric phase bioaccessible fraction (BAF%) ranged from 0.4% to 5.4% for chromium in soils overlying basalt and bioaccessible and total chromium concentrations are positively correlated. In contrast the range of gastric phase BAF for nickel was greater (1.4 to 43.8%), while no significant correlation was observed between bioaccessible and total nickel concentrations. However nickel BAF was inversely correlated with total concentration. Solid phase fractionation information showed that bioaccessible nickel was associated with calcium carbonate, aluminum oxide, iron oxide and clay related components, while bioaccessible chromium was associated with clay related components. This suggests that weathering significantly affects nickel bioaccessibility, but does not have the same effect on the bioaccessibility of chromium.

“…Studies (Haugland et al 2008;Jiao et al 2009b) show that PAHs in soils from Tianjin, China and Bergen, Norway were observed to have much higher concentrations of PAHs from their industrial region than other regions. The PAHs existed in polluted areas not only influence soil physicochemical characteristics, but also harm the environment and the people living in the actual region (Blake et al 2007;Mostert et al 2012).Thus, it is critical to remove PAHs in the soils of polluted areas.…”

Concentration, composition profile, orientation distribution, sources, and potential risks of 16 polycyclic aromatic hydrocarbons (PAHs) were analyzed in 76 surface (0-25 cm) soil samples collected from the Changzhi industrial district in July 2014 using a gas chromatography mass spectrometer (GC-MS QP2010 Ultra) system. The composition patterns of the PAHs were dominated by the presence of four-ring PAHs (average 42.9%), followed by three-ring (average 25.9%), five-ring PAHs (average 25.6%), two-ring PAHs (average 5.03%), and lastly, six-ring PAHs (average 0.641%). Source apportionment of the soil PAHs was also performed by the diagnostic ratios, principal component analysis (PCA), and coefficient of divergence (CD) analysis indicated signatures of PAHs sources (including incineration, coal/wood combustion, and vehicular exhaust emission). The total concentration of 16 PAHs (∑16PAHs) found in the roadsides soils (RS) ranged from 2197 to 25,041 μg kg, with an arithmetic mean value of 12,245 μg kg; followed by the village soils (VS), which ranged from 2059 to 21,240 μg kg, with a mean of 8976 μg kg; and lastly, the agricultural soils (AS), which ranged from 794 to 16,858 μg kg, with a mean of 3456 μg kg. According to the numerical effect-based soils quality guidelines of Maliszewska-Kordybach, the levels of PAHs in the sampled industrial areas range from high to heavy contamination. The values of total benzo[a]pyrene toxicity equivalent values (∑Bapeq16PAHs) in the sample areas ranged from 0.087 to 3611 μg kg with an average of 969 μg kg. According to the soil quality guidelines of Canada, values found in the highest range (100 μg kg), which are equal to those of ∑Bapeq16PAHs found in the industrial area samples, will exert adverse biological effects. The results of this research could potentially be useful for local governments to control toxicity exposure, promote actions to alleviate PAHs contamination, and to manage human health at both work and industrial areas.

“…Analysis of the chemical data obtained from the playgrounds in public parks in south-east Queensland indicated that most metals occurring in the surfaces of these playgrounds are derived from rocks occurring in the area. Other sources include various vehicular emissions (18.7%) and paints, probably derived from playground equipment (8.4%) (Mostert et al 2012). …”

Abstract:The pollution of urban soil with heavy metals caused by traffic activity is increasingly becoming a great threat to human health and environmental quality. This paper presents results of research of lead (Pb) and cadmium (Cd) distribution in land on playgrounds situated near busy streets in Cracow (Poland). Samples of sand and soil were collected from the most top layer (0-10 cm). Concentrations of examined metals are: Pb from 6.80 to 54.04 mg/kg and Cd from 1.60 to 2.61 mg/kg, respectively. The highest concentrations were found in sampling points near the busiest roads, and are particularly visible in the case of lead concentration in soil samples. For sand samples, metal concentrations are much lower. Although the results have not determined a high degree of soil's contamination, they indicate the problem of the children's exposure to toxic metals. Urban soil should be monitored particularly in such special places as playgrounds.
