Speciation of Cd in River Waters at Various Concentrations: The Results of Model Experiments

Data on the distribution of Cd species under a possible increase in technogenic load are presented. This research modeled the peculiarities of the redistribution of chemical Cd forms in river waters with contents that exceed the maximum permissible concentrations (MPCs). It has been shown that most of the introduced Cd can transit from the dissolved to the suspended form, thus stimulating the precipitation of suspended particles at the bottom at low flow rates.
