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.

Characteristics of alpaca wool from farmed animals located on different continents. Interest in breeding alpacas around the world is related to the acquisition of valuable fibre from these animals.The characteristics of alpaca wool are influenced by both genetic and environmental factors.The aim of the study was to compare chosen traits of Huacayaalpaca wool from three farms located in Australia, Africa and Europe.The wool samples were collected from 30 alpacas, 10 from each farm the assessed wool characteristics included: fibre diameter, level of medullation and staple length was determined. The following fibre types have been identified: with continuous medulla, with partial medulla and no-medullated.Similar results were obtained with respect to the fibre diameter, staple length, the level of medullation and even distribution of the type of medullated fibres in all tested farms.
