“…Up to 75% of all urban land has been estimated to be contaminated by chemicals [1]. Contaminated land has become an increasingly important economic, political, and social issue because of the reduction in the availability of green field sites for development and also the historical problems associated with the redevelopment of industrial sites (e.g., Love Canal in New York State, USA, Lekkerkerk in The Netherlands, and Georgswerder in Germany) [1,2]. In the United Kingdom, contaminated land is assessed purely as part of the planning process.…”

The effect of bone meal (Ca5(PO4)3OH) amendments on lead (Pb) bioavailability to Eisenia fetida (Savigny 1826) was investigated. A standard uncontaminated soil was amended with Pb(NO3)2 solution to give Pb concentrations of 7,000 microg/g of soil. After one week, bone meal was added to one half of the soil in the ratio 1:20 bone meal:soil. Immediately after addition of the bone meal, survival times of E. fetida were 23 and 41 h in the bone meal-free and bone meal-amended soil, respectively. Twenty-eight days after addition of the bone meal, survival times of Eisenia fetida were 67 h in the bone meal-free soil and more than 168 h in the bone meal-amended soil. In a second experiment, a standard Organisation for Economic Co-operation and Development reproduction toxicity test was carried out, but in addition to Pb(NO3)2 solution, bone meal was added to the soil in the ratio 1:20 bone meal:soil. The bone meal-free soil was left for five weeks before addition of E. fetida. In the bone meal-amended soil, bone meal was added to the soil one week after addition of the Pb. The soil was left for a further four weeks before addition of Eisenia fetida. Calculated toxicities were significantly lower for the bone meal-amended soil than those calculated for the bone meal-free soil. Twenty-eight-day median lethal concentrations (LC50s; concentration that is statistically likely to kill 50% of the exposed test organism within a given time period +/- 95% confidence intervals) of Pb were 4,379 +/- 356 microg/g of soil for bone meal-free soil and 5,203 +/- 401 microg/g of soil for bone meal-amended soil. Twenty-eight-day median effect concentrations (EC50s; concentration causing a reduction by 50% of a stated parameter) of Pb for weight change were 1,408 +/- 198 microg/g of soil for bone meal-free soil and 3,334 +/- 731 microg/g of soil for bone meal-amended soil and EC50s for cocoon production were 971 +/- 633 microg/g of soil for bone meal-free soil and 1,814 +/- 613 microg/g of soil for bone meal-amended soil. Significant mortalities occurred at Pb concentrations of 2,000 microg/g of soil in the bone meal-free soil and 5,000 microg/g of soil in the bone meal-amended soil. Earthworm Pb body load was lower in the bone meal-treated soil than in the bone meal-free soil up to a Pb concentration of 5,000 microg/g of soil. Earthworm Pb body load was approximately 100 microg/g of worm in surviving earthworms in both experiments when significant mortality occurred. Water and diethylenetriamine pentaacetic acid-extractable soil Pb showed good correlations with earthworm Pb body load. These extractions could be used as estimates for Pb bioavailability.

Short-term in situ immobilization of Cd and Ni by beringite and steel shots application to long-term sludged plots

-Beringite and steel shots were mixed with the upper 20 cm of the soil. One year after addition, the extractability in calcium nitrate (0.1 M) and the plant availability of soil-Cd and -Ni were investigated. The addition of beringite (5 % w/w) and steel shots ( 1 % w/w) led to a lower extractability of Cd and Ni. In the most contaminated plots, the extractability of Cd and Ni after 1 year had decreased, respectively, 54 % and 53 % for beringite and 41 % and 40 % for steel shots. The metal content in different organs of maize plants (shoots, sixth

Pot experiments were conducted at the department of Soil, Water and Environment, University of Dhaka to evaluate the effect of used tea leaves and poultry litter in ameliorating lead uptake and to alleviate toxicity of lead in Red amaranth (Amaranthus tricolor L.). The length, fresh weight and dry weight of shoot was decreased significantly by 34.83, 34.69 and 36.48%, respectively, in 200 mg kg-1 Pb treated pots compared to the control. The similar significant decreasing trend in case of macro nutrient concentration in shoot and root samples were also observed. %N, P, K, S, Mg and Ca concentration in edible parts (shoots) decreased by 66.3, 5.27, 52.17, 30.32, 61.54 and 62.87% in 200 mg kg1 lead (Pb) treated pots compared to the control. On the other hand Pb concentration in shoot and root was the highest at 200 mg kg-1Pb treated pots (55 and 189 mg kg-1 pot-1) and the lowest was in the control treatment (0.45 and 20 mg kg-1 pot-1). Biomass production were positively influenced by the application of organic amendments as well as lead uptake was significantly ameliorated into Red amaranth shoot and root due to application of used tea leaves and poultry litter which reduced soil to plant transfer (TrF) of Pb by 47.39, 56.34 and 16.67, 22.22% in shoots and roots of red amaranth, respectively, compared to the untreated pots.
