Distribution of lead, cadmium, copper, zinc and iron in wool fleece

Concentrations of lead, cadmium, copper and zinc in Lowland and Merino wool fibres were determined using differential pulse voltammetry, and iron concentration was measured by means of the spectrophotometric method. A differentiation in the concentration of the above elements in the same staple was Pb: 13.5-29.31 [mg/kg]; Cd: 0.95-4.59 [mg/kg]; Zn: 57.21-91.34 [mg/kg]; Cu: 2.79-5.91 [mg/kg]; Fe: 58.94-830.08 [mg/kg] for Polish Merino fleece, and Pb: 5.88-11.79 [mg/kg]; Cd: 1.35-4.92 [mg/kg]; Zn: 55.52-86.85 [mg/kg]; Cu: 1.66-4.58 [mg/kg]; Fe: 70.27-614.34 [mg/kg] for Polish Lowland fleece. The effects of metal pollution on structural and utilizable conditions were investigated.
