Arbuscular mycorrhiza contribution to the growth performance and heavy metal uptake of Helianthus annuus LINN in pot culture

  A greenhouse experiment was conducted to assess the arbuscular mycorrhiza contribution to the growth performance and heavy metals (Cd and Pb) uptake ofHelianthus annuus L. from polluted soils. Cadmium sulfate (CdSO4.8H2O) and lead acetate ((CH3COO)2Pb.3H2O) were applied at the concentrations: Cd- 0,20,40,60,80 mg kg-1 and Pb-0,250,500,750,1000 mg kg-1 in 90 plastic pots filled with 5 kg ...

Lead and zinc concentrations in hair and nail of some Kano inhabitants

  The advantages of hair and nail tissues analysis over other biological samples are that trace metal concentrations in them are not subjected to rapid fluctuation due to diet, air and water hence a long term stable nutritional status. Lead and zinc concentrations in hair and nail samples were determined by flame atomic absorption spectrophotometer (AAS). The mean zinc concentration in hair and nail were 0.695...
