Samples of soils, green parts and flowers of melliferous plants collected from an industrialized region (A) and an ecological region (B) were shredded to below 2 mm to det. Ag and Ni contents by using at. absorption spectroscopy with flame excitation. Samples from B region contained less of tested elements than those from A region except for Ag in plants (green parts and flowers). Ni contents were much higher than Ag contents for all types of samples in both analyzed regions.
