“…Their presence has implications for environmental health due to potential uptake by plants (Harding and Witton 1981;Jopony and Young 1993) and animals (Abrahams and Steigmajer 2003) and creates the possibility for the remobilization of contaminated sediments through erosion processes (Dennis et al 2003;Macklin and Lewin 1989). Indeed, a number of studies have noted that the presence of contaminated floodplains can lead to the enrichment of contemporary fluvial sediments long after the cessation of mining activity (Leenaers 1989;Macklin and Klimek 1992;Owens et al 1999).…”

Dispersal of Contaminant Metals in the Mining-Affected Danube and Maritsa Drainage Basins, Bulgaria, Eastern Europe. Water Air and Soil Pollution, 206(1-4), 105-127. Sponsorship: Royal Society Joint ProjectMetal dispersal in the Danube and Maritsa drainage basins resulting from metal mining activities in Bulgaria has been assessed through the collection of 611 samples of river water, river channel and floodplain sediment, and mine waste from over 218 sites. Concentrations of Cd, Cu, Pb, and Zn in river water were found to be highest in close proximity to locations of Cu and Pb?Zn mining regions in the Maritsa catchment. Downstream dispersal of solute metals in these catchments, and into the River Danube, was found to be limited by physical dilution and a well-buffered pH environment. Dispersal of contaminant metals in channel and floodplain sediment was found to be extensive. Contamination was particularly severe in the Rivers Timok and Iskar (Danube catchment) and the Topolnitsa, Chepelarska, and Arda Rivers (Maritsa catchment) and creates the potential of transboundary dispersal of contaminant metals.Peer reviewe

“…In order to encourage tillering and normal sward formation, grass plants were cut down to the column rims with stainless steel scissors, leaving 1 cm of visible growth. The harvested plant material was discarded, as metal uptake by immature plants grown in pots may be atypical of that seen in subsequent harvests (Jopony and Young, 1993). Following the preliminary harvest, 20 mL of 0.02 M KNO 3 was added to the columns that contained the urban soils.…”

“…Sauvé et al (1998) examined the toxicological impact of (Cu 2+ ) and (Pb 2+ ) upon a variety of crop plants, soil organisms and soil microbial processes and found that the free metal ion activity explained toxic responses to a greater degree than the total soil metal concentration. Similarly, a number of studies have also focussed on metal concentration in the soil solution, [M soln ], as an indicator of intensity (Gerritse et al, 1983;Jopony and Young, 1993;Minnich et al, 1987).…”

Evaluating a ‘Free Ion Activity Model’ applied to metal uptake by Lolium perenne L. grown in contaminated soils.

We investigated several formulations of the 'free ion activity model' (FIAM) as a means of describing plant uptake of soil Cd and Zn from contaminated soils. Lolium perenne was grown on a range of urban and metal-spiked agricultural soils selected to provide a wide range of Cd and Zn concentrations, pH values and other physicochemical properties. Plants were grown under controlled conditions and above-ground biomass was harvested at regular intervals. Concentrations of Cd and Zn in the grass were compared with estimates of metal 'capacity' (total or radio-labile metal content in the soil) and 'intensity' (metal concentration in the soil solution or free divalent ion activity). The results suggested that 'capacity' terms alone were poor predictors of plant metal uptake (r 2 values between 0.001 and 0.43), while metal ion 'intensity' provided quite reasonable predictions of the variation observed for several harvests of the grass (r 2 = 0.60-0.87). Soil solution-to-plant transfer factors were highly pHdependent which may suggest significant competition between trace metals and protons for sorption sites on roots. However, resolution of this question was confounded because of the strong co-variance between pH and p(M 2+ ) in the soil pore water. Thus the influence of pH could not be separated from the effect of changing metal ion activity on uptake rate. Other possible effects on metal uptake such as dilution from increased biomass during growth and competition for uptake between different metal ions (Zn vs. Cd), or with Ca 2+ , appeared to play very minor roles in determining bioavailability. Several formulations of the FIAM failed to provide a consistently superior prediction of metal uptake when compared to purely empirical regression with pH and p(M 2+ ) within the range of the data used to parameterise the models.

“…However, the extraction efficiency of the 0.01 mol CaCl 2 L − 1 is too low. EDTA normally extracts more Pb than plant uptake (Jopony and Young, 1993). Diluted HCl solution is often recommended for extracting heavy metals in acid soils.…”
