Patterns in the distribution of several chemical elements in bottom sediments and soils of the Ivankovo Reservoir area,Volga River valley

This paper discusses the distribution of trace elements in certain genetic horizons of flooded soils and riverside soil cover and compares it with the heavy metal distribution in bottom sediments of the Ivankovo Reservoir area in the Volga River valley. We present data on the chemical and grain-size compositions of bottom sediments and the concentrations of biophile elements and humus in these sediments. Correlation and factor analyses were applied to reveal the relationships between the abundances of heavy metals and humus and the grain-size composition.
