“…A significant coefficient of correlation between the total zinc content and the sum of its extracted and determined fractions in the soils analyzed (r = .99, a = .001) and a small mean error in the sum of determinations of the zinc in the fractions (4.8%, the range being from 0.36 to 14.8%, SD = 4.0%) indicate a high accuracy of the determinations, comparable to those achieved by some other authors (Iyengar et al, 1981;Scokart et al, 1987;Shuman, 1985).…”

In 49 soil samples, total zinc was distributed mainly among and residual Zn (55.2%) fractions. Water-soluble Zn and nonspecifically ad sorbed, exchangeable Zn, specifically adsorbed, exchangeable Zn, and organicall bound zinc fractions contained on average 1. 1, 2.4, 7.4, and 12.8%, respectively, of this microelement. Correlations were sought between soil factors such as pH, sorptiv capacity, fines and colloidal particles, organic matter, and concentrations of Zn in th various fractions. Acid soils contained a greater share of water-soluble and nonspecifically adsorbed, exchangeable Zn, while those with neutral pH contained a greater share of specifically adsorbed Zn, Mn-and Fe-bound Zn, and residual Zn. Higher amounts af fines and colloidal particles correlated with lower amounts of non specifically and specifically adsorbed, exchangeable Zn and at the same time with higher amounts of Zn bound to manganese and iron oxides and immobilized Zn. The toxicity of Zn in soil, which may be taken up by plants and enter waters, represents a real danger in the case of acid soils low in fines and colloidal particles. This pertains particularly to soils near potential sources ofZn contamination.

“…They have been shown to be an efficient method of conducting comparative studies between natural and contaminated land, as well as areas characterized by different types of contamination (Scokart et al, 1987;Hirner, 1992;Hooda and Alloway, 1994;Tack and Verloo, 1995;Gauthreaux et al, 1998;Wada and Wada, 1999). Sequential extraction has been used to compare metal fractionation in natural soils (Shuman, 1979;Barona and Romero, 1996) and the change in metal distribution over time in soils treated with sewage sludges (Nyamangara and Mzezewa, 1999;Walter and Cuevas, 1999).…”

This paper presents a critique of current methods of sampling and analyzing soils for metals in archaeological prospection. Commonly used methodologies in soil science are shown to be suitable for archaeological investigations, with a concomitant improvement in their resolution. Understanding the soil-fraction location, concentration range, and spatial distribution of autochthonous (native) soil metals is shown to be a vital precursor to archaeological-site investigations, as this is the background upon which anthropogenic deposition takes place. Nested sampling is suggested as the most cost-effective method of investigating the spatial variability in the autochthonous metal concentrations. The use of the appropriate soil horizon (or sampling depth) and point sampling are critical in the preparation of a sampling regime. Simultaneous extraction is proposed as the most efficient method of identifying the location and eventual fate of autochthonous and anthropogenic metals, respectively.

“…Following the reduction of lead as an additive to gasoline in the late 1980s, the contribution to indoor dust by direct deposition of atmospherically transported lead from this source is likely to be of little importance. However, the contribution of historically deposited gasoline lead to urban soil is highly significant as lead generally has a long residence time in soil [ 16].…”

The lead particle content of floor dust in a housing unit scheduled for interior lead paint hazard removal was characterised microscopically to identify the contributing source(s) of the lead. It was hypothesised that elevated levels of lead in the dust resulted from the deterioration of the lead-based paint on the indoor surfaces. The question of lead particle source attribution was addressed using a combination of scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). SEM/EDS provided data on the size, shape, and composition of the individual lead-containing dust particles. The floor dusts which were analysed contained a variety of lead particle types and eight of these types from several rooms exhibited unique morphological and/ or chemical characteristics. These were variously classified as lead paint particles. The lead levels in the floor dusts prior to the abatement were ≥ 100 μg.ft -2 . The floor dust lead concentrations immediately following the abatement were all less than the pre-abatement levels, but a re-sampling 2 months after the abatement found that the amount of lead in two of the rooms was approximately 3 and 4.5 times higher than the levels prior to the abatement. SEM/EDS analysis of the floor dusts samples collected 2 months after the abatement showed that in these two rooms the constituent particulate lead differed from that in any of the pre-abatement dusts. Following attempts to identify possible sources of recontamination, it was found that this previously unidentified particulate lead was consistent in form with lead scraped from the interior of one of the radiators which had been removed from the complex some time after the abatement. Residual water spilling from the radiators during the course of removal was, in all likelihood, the cause of the unexpectedly elevated dust lead levels.
