The distributions of concentrations of dissolved Sr, Ca, F, and B in the Kuban and Don mouth areas are studied. It is found that the behavior of F and B is conservative, whereas that of Sr and Ca is slightly nonconservative and is associated with the spatial heterogeneity of the structure of the zone where the river and sea waters are mixing (this heteromogeneity can arise because of dissimilar transformation of continental river runoff in different areas of the near-mouth coastal waters). It is shown that the parameters of linear relationships between the concentrations of Sr and Ca and the chlorides content of water differ in accordance with the seasonal variations in the chemical composition of the river and the Sea of Azov waters; for F and B, such regularity is not found. 相似文献
