During the last decade of the 20th century and at the beginning of the 21st century, among other agriculture related issues, two interconnected issues have come into focus: food security issue on one hand and food safety issue on the other hand. Th is has resulted in a number of projects launched within EU countries which could all have one common heading: from the producer to the consumer or from the fi eld to the table; so called food route. Th is way we always have information where raw material, food item or product are produced, in what way and in what soil it has been grown, what was used for its fertilization, and where it was stored. Special attention has been given to the soil and its quality, in particular to soil contamination by various pollutants. As we know, some metals (Fe, Mn, Zn and Co) are biogenic elements which are phytotoxic in high concentrations, and their presence in the food chain in quantities above allowed levels may cause acute or chronic diseases. Th e foregoing and some other microelements (Cu and S) tend to accumulate unlimitedly in living organisms – plant tissue, which is particularly dangerous in contaminated sites which were included in these investigations.
