Among heavy metals of automotive origin the most dangerous are lead, cadmium, copper, and nickel. They accumulate in the soil and plants and thus are incorporated into the food chain, and subsequently gather in animal and human tissues [4]. These metals are often not excreted from the organisms, but are amassed within the bones, the kidneys, the liver, and the brain, contributing to the emergence of various diseases, including cancer. The content of these precise elements in soil along communication routes is most often monitored. It is also crucial to monitor the content of these elements in individual parts of the plants occurring in the areas of immediate vicinity to communication routes. Plants accumulate heavy metals in a variety of their organs – in the roots, leaves, or stems. It is therefore vital to determine the magnitude of the environmental risk of heavy metals resulting from communication pollution. All the undertaken actions allow the introduction of rational engineering solutions at the road design stage, which would increase environmental protection.
