Abstract:

On the basis of data concerning small catchments not polluted bymunicipal and industrial sewage we calculated the solute yield from rural areas.Calculations were carried out in a simplified way, taking into consideration the meansolute concentrations from data for the years 1976-1985, and mean discharges of riverwaters. For 20 selected larger catchments of the Vistula tributaries we also calculatedthe total solute yield, i.e. including the sources of municipal and industrial wastewater.On the basis of these and other data we attempted to analyse the balance of the soluteyield. Components taken into account come from: precipitation, agricultural chemicals,farm sewage, municipal and industrial wastewater, and chemical denudation of thelithosphere. Results were considered in relation to regional differentiation. Essentialchanges in the solute yield structure were also noted in comparison with the period ofthe 1930's.

Abstract:

In the period between the two World Wars studies of prices of food articles in Poland were carried out. The particular authors, however, dealt with relatively short periods and did not pay attention to secular oscillations. The results of studies of three different authors made it possible to plot for Cracow a diagram of prices expressed by a silver equivalent, comprising the period 1369-1914. Besides general tendencies depending on economic conditions, long-term oscillations corresponding with climatic changes are found in this diagram. Three periods of a relatively rapid growth of prices can be distinguished which correspond with three cooling waves during "Little Ice Age": I — from the middle of the 14th c. to the middle of the 15th c.; II — from about 1520 to the turn of the 17th and 18th c.; Ill — from 1700 to 1850/1890.
