“…All metal concentrations (As, Cd, Cr, Hg, Ni and Pb) were higher than those found in the present study. The current mean Pb and Cd concentrations in soil samples collected in the vicinity of the HWI are also lower than those found in forest soils from Mexico City (Morton-Bermea et al, 2002), whereas similar levels of Pb were found in vegetable garden soils from Hangzhou, China (Wuzhong et al, 2004). With respect to vegetation, higher mean concentrations of a (Liu et al, 2006).…”

In recent years, incineration has been demonstrated to be a commercially available technology for hazardous waste (HW) disposal (Richter and Johnke, 2004). However, because of the potential adverse effects of toxic emissions, waste incinerators are still an important cause for concern for the public. In spite of that, compliance with current EU emissions has vastly reduced the probability of adverse health effects (Glorennec et al., 2005). With respect to metals, a number of studies have shown that these elements are emitted by industrial, medical and municipal waste incinerators (Schumacher et al., 1997; Rimmer et al., 2006). Filter ash is an especially problematic residue because it contains high metal concentrations (Lisk et al., 1989). After combustion in modern HW incinerators (HWIs), metals contained in HW are mainly collected in bottom and fly ash, with only small quantity of metals being discharged from the stack as particulate matter or vapor (Jung et al., 2004). However, the atmospheric emission of these elements is a matter of concern.

“…Moreover, compared to the controls (29.9 and 35.3 mg kg -1 , samples N-2a and N-2b), there is significantly higher concentration of Pb in the soil affected by oil spillage. There is a clear relation between lead and oil pollutant concentrations, indicating that contamination with Pb is a direct consequence of oil pollutants presence, most probably of the gasoline type 19 . Namely, it is well known that tetraethyl-and tetramethyl-lead are gasoline additives designed to increase octane rating 20 .…”

Heavy Metals in Petroleum‐Contaminated Surface Soils in Serbia

2004

Investigation of heavy metal contamination levels as well as their association types with substrates in petroleum-contaminated surface soil was carried out using modified sequential extraction method. In that way, remobilization capacity of metal cations, both in natural conditions and in accidents, has been studied. Moreover, partitioning of heavy metals, originating from spilt oil derivative, among surface soil substrates was estimated. Extreme contamination with lead was discovered, as well as the increased concentrations of zinc and copper. Oil-derived Pb and Zn were found to be distributed between carbonates and amorphous Fe-oxides, whereas Cu was found to be dominantly associated with amorphous Fe-oxides. Appreciable amounts of these metals were also found to be incorporated into more resistant structures. In petroleum-contaminated surface soil, substrates of cadmium are carbonates, whereas nickel has the great affinity toward hydrous Mn-oxides. Cd is proven to be the most mobile metal in oil-contaminated surface soil.

“…The natural concentration of heavy metals in arable soil depends primarily on the geological parent material composition (Morton-Bermea et al 2002). Native concentrations of heavy metals are relatively high in shales and clays, and usually lower in sands and limestones.…”

This investigation was performed in order to clarify the degree of heavy metals pollution in forest, agricultural and industrial surface soil samples in relation to pre-anthropogenic soils of Almyros region, in Central Greece. In 2004 and 2005 soil samples were collected and analysed for available (DTPA method) and total (Aqua Regia method) Cd, Cr, Cu, Pb, Zn and Ni concentrations. For each metal the enrichment factor with respect to the levels in pre-anthropogenic soils was calculated. All the types of soils appeared to be less polluted than in other investigations. In agricultural and industrial soils the available Cd concentration was higher than the other metals studied. The enrichment factor of Cu in relation to total concentration has the maximum value of the metals studied.
