“…Perhaps the bioavailable levels of toxic Cr and Pb were similar in all the soil samples. Several factors, including organic matter, pH, and redox potential might influence the solubility of heavy metals (9,18,25). In the case of Cr, the oxidation state of the metal impacts mobility and toxicity; Cr(VI) is several orders of magnitude more toxic than Cr(III).…”

Microbial community composition and activity were characterized in soil contaminated with lead (Pb), chromium (Cr), and hydrocarbons. Contaminant levels were very heterogeneous and ranged from 50 to 16,700 mg of total petroleum hydrocarbons (TPH) kg of soil ؊1 , 3 to 3,300 mg of total Cr kg of soil ؊1 , and 1 to 17,100 mg of Pb kg of soil ؊1 . Microbial community compositions were estimated from the patterns of phospholipid fatty acids (PLFA); these were considerably different among the 14 soil samples. Statistical analyses suggested that the variation in PLFA was more correlated with soil hydrocarbons than with the levels of Cr and Pb. The metal sensitivity of the microbial community was determined by extracting bacteria from soil and measuring In microcosm experiments with these samples, microbial biomass and the ratio of microbial biomass to soil organic C were not correlated with the concentrations of hydrocarbons and heavy metals. However, microbial C respiration in samples with a higher level of hydrocarbons differed from the other soils no matter whether complex organic C (alfalfa) was added or not. The ratios of microbial C respiration to microbial biomass differed significantly among the soil samples (P < 0.05) and were relatively high in soils contaminated with hydrocarbons or heavy metals. Our results suggest that the soil microbial community was predominantly affected by hydrocarbons.

“…K d values for zinc of 140 and 41 L/kg were determined for the O-horizon (organic layer) and E-horizon (silty sand), respectively, of a podzol forest soil (Bunzl and Schimmack 1989). Field-based K p ranged from 6 to 6,762 L/kg for 20 Dutch agricultural soils (Janssen et al 1997). K d values for nine soils treated with sewage sludge supernatant ranged from 0.034 to 1.359 L/g at pH 4.5 while at pH 6.5, K d values ranged from 0.425 to 2.896 L/g (Gao et al 1997).…”

“…Distribution constants (K d =concentration of sorbed zinc/concentration of zinc in solution) for zinc in soil range widely from 0.1 to 8,000 L/kg (or mL/g) (Baes and Sharp 1983;Bunzl and Schimmack 1989;Gao et al 1997;Gerritse et al 1982;Janssen et al 1997). K d values of 100±770 mL/g for sandy loam soil and 0.2±4 mL/g for sandy soils were reported by Gerritse et al (1982).…”

“…Janssen et al (1997) reported that pH was in fact the only soil parameter of significance for partitioning Pb, Zn and other metals between the soil solution and soil solid phases. In our study, soil pH affected the proportion of Pb bound to soil oxides and, highly significantly (P < 0.001), the exchangeable Pb and Zn.…”

Sequential extractions, metal uptake by Taraxacum officinale, Ruby's physiologically based extraction test (PBET) and toxicity characteristic leaching procedure (TCLP), were used to assess the risk of Pb and Zn in contaminated soils, and to determine relationships among soil characteristics, heavy metals soil fractionation, bioavailability and leachability. Regression analysis using linear and 2 nd order polynomial models indicated relationships between Pb and Zn contamination and soil properties, although of small significance (P < 0.05). Statistically highly significant correlations (P < 0.001) were obtained using multiple regression analysis. A correlation between soil cation exchange capacity (CEC) and soil organic matter and clay content was expected. The proportion of Pb in the PBET intestinal phase correlated with total soil Pb and Pb bound to soil oxides and the organic matter fraction. The leachable Pb, extracted with TCLP, correlated with the Pb bound to carbonates and soil organic matter content (R 2 = 69%). No highly significant correlations (P < 0.001) for Zn with soil properties or Zn fractionation were obtained using multiple regression.
