Comparative Study of Heavy Metal Content in Bilbery and Raspery from Farm Cuture
Abstract
The aim of this study is testing the accumulation of heavy metals in bilberries (Vaccinium myrtillus)
and raspberries (Rubus idaeus), focusing on their variability, bioaccumulation patterns, and potential
health risks. Both fruits are known for their nutritional benefits but are also capable of absorbing heavy
metals like cadmium (Cd), lead (Pb), and zinc (Zn) from their environments. The study reveals that
titanium (Ti) and iron (Fe) are the most abundant metals in both fruits, with bilberries showing higher
levels of manganese (Mn), cadmium, and silver (Ag), while raspberries exhibit greater concentrations
of zinc, chromium (Cr), and tin (Sn). The results highlight species-specific differences in metal uptake,
likely influenced by environmental factors such as soil composition and contamination levels. Toxic
metals like cadmium and silver are more prevalent in bilberries, raising safety concerns for their
consumption. Pearson correlation analyses and clustering patterns reveal relationships between
various metals, indicating shared environmental pathways or distinct accumulation mechanisms.
