The influence of anthropopression on plants cover and deposition of trace elements within the region of bottom sediments of hydraulic structures – the examples from polish carpathians streams

key words: anthropopressure, mountain streams, sediments, heavy metals, plant cover

Summary:

The aim of the following paper was to present the level of the chosen trace elements such as: Cd, Cr, Cu, Ni, Pb and Zn which were deposited within the bottom sediments in the region of hydraulic structures. Special attention was put to sediments trapped in the pools of check-dams and small channel bars found along the channelized parts of the mountain streams. The research was conducted on three Polish Carpathian streams: the lłynne stream, the Kudowski, and the Lubanski stream – all in the Gorce Mountains. All of the investigated streams are partly channalized and partly are in natural conditions. The contamination was stated in sediments of the Mlynne Stream in case of Ni, Cu and Cr. The sample were collected upstream the barrage (Ni and Cu) and ad the barrage Cr. The plant covers were determinated mainly by hydraulic structures. In case of vegetation the biggest anthropopression was stated in upstream of barrage sections located on the Mlynne and Kudowski Streams.
