Lead belongs to trace elements strongly degrading the natural environment. One of the elements of the environment that can be polluted is water, which plays a special role in the movement of elements. Water quality is of great importance for the proper functioning of the environment, which is why water requires protection against pollution of elements. Taking appropriate actions to protect the aquatic environment requires the determination of the element’s content in plants, soil as well as in waters so that it can be predicted to pass to other elements of the trophic chain. The aim of the research was to determine the impact of anthropogenization of the natural environment on the content of lead in grasses, soil and in leachates. The basis of the research was a pot experiment, which was carried out in four groups of vases containing soils with growing cadmium pollution. The plant used for the research was the quackgrass (Elymus repens). During the experiment, three swaths were collected in which the lead content was measured. The highest content of this element was determined in the vegetation samples from the control combination. The presence of trace elements in soils may affect their concentration in water, therefore, after the end of the pot experiment, samples of leachate were taken to investigate whether increasing amounts of cadmium in the soil can affect the content of lead in the effluents. It was noted that the leachate from the control group and group I, contaminated with cadmium to the smallest extent, was characterized by a higher concentration of lead than in other groups of the experiment.
