nr 2

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.

nr 5

The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from various places in Bielsko Biała and the neighbouring area. Samples were digested by the wet method in a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified reference material was applied for calibration and validation of analytical procedures.
