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.
