pierwiastki sladowe - Opis:
- Fluvial and slope deposits were investigated in the NW part of Masovia region. Their deposition was conditioned by anthropopression. There were recognised lithological features and analysed in vertical profiles such characteristics as: grain size, organic matter and selected elements (eg. Zn, Pb, Cu, Cd, Ni, P). Selected samples with organic matter were dated using the radiocarbon method. Age of sediments and their sedimentological and geochemical characteristics let to destinguish the series of deposits correlated with such periods of human activity as: Wielbark and Przeworsk cultures, the Middle Ages, the modern and industrial periods with last 100 years heavily affected by human activity. A very characteristic feature of the study area is a general very small content of analysed elements - close or very near to values of geochemical bacground but it is varied in vertical profiles of both slope sediments and fluvial ones. In the area of Brudzeń Duży the highest concentrations of analysed metals were recorded in the sediments accumulated during the Middle Ages, especially early phases of this period, what corresponds to the economic activity of the Slavs in this area (the two strongholds in Brudzeń Duży and Parzeń). Thereafter it was an agricultural region. In the area of Borowiczki the maximum concentrations occur at the land surface and it is correlated with the human activity of the last 40 years - that is, since the creation and operation of petrochemical plant in Płock. The carried studies indicated that trace elements in sediments, even occuring in small concentrations may be helpful in separating the layers by the age of deposition and in determining the rate of sedimentation at footslopes or in valley bottoms (overbank during the floods).
