“…It is also interesting to note that the trend of Pb:Cd NERs of the soils (Oxisol > Ultisol > Mollisol) paralleled the pro portions of variable charged surfaces (oxidic minerals, 1:1 phyllosilicates, and organic matter), and were opposite CEC trends (Table 1). Therefore, on a relative basis, compared to Cd, Pb appeared to have a very high specificity for variable charged surfaces compared to constant surface charge mate rials (Brummer et al, 1983;Forbes et al, 1976;Jenne, 1968;McKenzie, 1980).

The sorption and desorption of Pb and Cd in tropical soils is strongly influenced by the order in which these metals enter the soil environment. AbstractIt is important to examine mechanisms of Pb and Cd sorption in soils to understand their bioavailability. The ability of three tropical soils to retain Pb, Cd, and Ca was evaluated. The objectives of this study were to (1) determine the extent to which soil sorption sites are metal specific, (2) investigate the nature of reactions between metals and soil surfaces, and (3) identify how metals compete for sorption sites when they are introduced to soils sequentially or concurrently. Lead was shown to be much less exchangeable than Cd and inhibited Cd sorption. Cadmium had little effect on Pb sorption, though both Ca and Cd inhibited the adsorption of Pb at exchange sites. Lead appears to more readily undergo innersphere surface complexation with soil surface functional groups than either Cd or Ca. Thus, regardless of when Pb is introduced to a soil, it should be less labile than Cd.

“…Exchange reactions hold ions electrostatically using surface charges and attachment is sufficiently weak to enable them to be replaced by other ions. Secondary oxides of iron and manganese present as coatings on fine surface particles scavenge trace elements by mechanisms such as, co-precipitation, adsorption, surface complex formation, ion exchange and penetration of the lattice (Jenne 1968, Ellis 1979, 1985. Mineral dissolution, precipitation and complex reactions are controlled by hydrogen ion activity (pH) and redox potential (Eh).…”

In this study, geochemical and particle size analyses of thirty-four street sediment samples collected from an urban environment around Guanabara Bay, shows highway run-off to be a potential source of heavy metals for the pollution of near-shore sedimentary deposits. Concentrations of Fe, Mn, Zn, Cu, Pb, Cr and Ni were found to be higher in these sediments when compared to concentrations found in samples from the natural environment, where an Enrichment Factor (EF) index was used to distinguish between natural and anthropogenic sources. Particle size analysis shows these sediments to be predominantly composed of sand and no distribution pattern was observed between the sand, silt and clay fractions. High levels of organic matter and heavy metals would indicate that these street run-off materials are a potential source of pollution for the near-shore sediments of Guanabara Bay.

“…Many studies have examined the concentration and retention of metals in soils and the effect of various parameters on their adsorption and solubility, including pH (McBride and Blasiak, 1979;Cavallaro and McBride, 1980;Harter, 1983;Robb and Young, 1999;Green et al, 2003), redox conditions (Davranche and Bollinger, 2001;Davranche et al, 2003;Qafoku et al, 2003), amount of metals (Garcia-Miragaya, 1984;Basta and Tabatabai, 1992;Sauvé et al, 2000), cation exchange capacity (Ziper et al, 1988), organic matter content (Gerritse and Vandriel, 1984;Elliot et al, 1986;Benedetti et al, 1996aBenedetti et al, , 1996bKinniburgh et al, 1999;Kashem and Singh, 2001), soil mineralogy (Tiller et al, 1963;Jenne, 1968;Kinniburgh et al, 1976;Cavallaro and McBride, 1984;Kuo, 1986;Lindroos et al, 2003), biological and microbial conditions (Gerritse et al, 1992;Dumestre et al, 1999;Warren and Haack, 2001) as well as developing assemblage models to mechanistically predict these processes (Dzombak and Morel, 1987;Haworth, 1990;McBride et al, 1997;Celardin, 1999;Weng et al, 2002;Impellitteri et al, 2003, Tye et al, 2003. From these studies it has emerged that total soil metal content alone is not a good measure of short-term bioavailability and not a very useful tool to determine potential risks from soil contamination (Tack et al, 1995;…”

Chemical elements that are either present naturally in the soil or introduced by pollution are more usefully estimated in terms of 'availability' of the element, since it is this property that can be related to mobility and uptake by plants. A good estimation of 'availability' can be achieved by measuring the concentration of the element in soil pore water. Recent achievements in analytical techniques allowed to expand the range of interest to trace elements, which play a crucial role both in contaminated and uncontaminated soils and include those defined as potentially toxic elements (PTE) in environmental studies. A complete chemical analysis of soil pore water represents a powerful diagnostic tool for the interpretation of many soil chemical phenomena relating to soil fertility, mineralogy, and environmental fate. This chapter describes some of the current methodologies used to extract soil pore water. In particular, four laboratory-based methods, i) high speed centrifugation-filtration, (ii) low (negative-) pressure Rhizon™ samplers, (iii) high pressure soil squeezing and (iv) equilibration of dilute soil suspensions, are described and discussed in detail. A number of operational factors are presented: pressure applicable (i.e., pore size involved), moisture pre-requisites of the soil, pore water yielding, efficiency, duration of extraction, materials and possible contaminations for PTE studies. Some consideration is then taken to assess advantages and disadvantages of the methods, including costs and materials availability.
