Uferbach catchment, lower Saxony, Harz mountains, Germany | Mining of Fe ores (pyrite and marcasite) | Four phases of mining and smelting activities in the catchment were distinguished | [15] |
Geul river, Belgium | Pb-Zn mining | Metal fluxes back to the 17th century were reconstructed. Vertical profiles are subdivided into three major units corresponding to different industrial periods | [16] |
Ouse river, UK | Pb mining | Geochemical and mineralogical analysis of sedimentary profiles gave evidence that contamination by lead mining began in the Roman period | [7] |
Rio Tinto, Spain | Mining of a massive sulphide deposit | Dating of cores from the alluvial plain indicated that mining of sulphide deposits go back to 3000 years BP | [17] |
Wurm river, west of Germany | Municipal wastewater and industrial pollution | Degree of recent and historical pollution of alluvial soils and diachronic sedimentation rates varied explicitly over a small scale sedimentation rates were derived and varied in a range 0.6–1.3 cm a−1 | [18] |
Maoniu river and the AnningRiver, Sichuan, China | Rare elements mining | Based on 210Pb dating and element concentrations of the sediment core, it was found that the Cd accumulation rate of the flood plain increased from 0.16 to 2.22 μg·cm−2·yr−1 over the past 100 years | [19] |
Morava river, Czech Republic | Industrial contamination | Changes in sedimentation rate can be attributed to erosion of the past channel system likely due to climatic extremes | [21] |
Morava river, Czech Republic | Industrial contamination | Sediments from regulated river banks qualitatively reflected the actual, local contamination of the river system | [20] |
Litavka river, Czech Republic | Polymetallic (Ag–Pb–Zn–Sb) ore mining and smelting | Integration of geochemical analysis, stratigraphic correlations adopted from fluvial sedimentology, historical maps, and aerial photographs using geoinformatic systems | [22] |
Ohře river, Germany and Czech Republic | Ancient and modern ore mining | Most contamination of the Ohře is due to Hg and U found in sediments stored in historic channels. Necessity to use GIS tools and appropriately selected sampling sites with respect to past channel dynamics | [23] |
Ploučnice river, Czech Republic | Uranium mining | Very detailed study, integrating geochemical analysis, geophysical methods knowledge of fluvial systems, and the evaluation of historical maps and aerial photographs using geoinformatic systems | [24] |
