摘　　要：Many temporary and permanent reservoirs of water occur on or near coal-waste dumps in the Lower-and Upper Silesian Coal Basins(Poland).Little or nothing is known of the degree to which their water chemistry might reflect(i)reservoir type,i.e.,whether permanent or temporary,(ii)level of coal-waste thermal activity,i.e.,whether inactive or self-heating or burnt-out or(iii)region,i.e.,whether the dumps are in Upper-or Lower Silesia.To provide some answers,concentrations of selected ions(NH_(4)^(+),HCO_(3)^(-),F^(-),Cl^(-),Br^(-),NO_(2)^(-),NO_(3)^(-),PO_(4)^(3-),SO_(4)^(2-))were determined by ion chromatography and of nineteen elements(Al,B,Ba,Ca,Cd,Cr,Cu,Fe,K,Li,Mg,Mn,Na,P,Pb,S,Si,Sr,Zn)by inductively coupled plasma mass spectrometry(ICP-MS).The data allow a number of the following observations.When permanent reservoirs are considered,there is a clear relationship between concentrations of ions and major and trace elements and dump thermal activity.The highest concentrations occur where the thermal activity is high as inorganic components are transformed into more water-soluble forms.As dump thermal activity shows a regional pattern,it follows also that elemental and ion concentrations in the dump waters show significant regional differences.In temporary reservoirs,concentrations of ions and major and trace elements are much lower and any correlations between components less significant than in the permanent reservoirs;these reservoirs exist for too short a time for any balance between coal waste-and water components to be established.
