Effect of bottom sediments on the nutrient and metal concentration in macrophytes of river-lake systems
Our research concerns functioning of the river-lake system through an analysis of factors affecting the assimilation of biogenes and metals by aquatic plants typical for such a system. The greatest effect on the accumulation of an excessive amount of substances like nutrients and heavy metals occurring in the water ecosystem of the river and lake system seems to be demonstrated by the properties of the bottom sediments, mainly their granulometric composition. On the other hand, it was demonstrated that aquatic plants can have an effect on the fraction size in sediments, particularly near the outlet of the river to the water body.The obtained results could contribute to the creation of controlled conditions favouring contamination capture, which could a ffect the advancement of knowledge concerning the functioning of freshwater aquatic ecosystems.
