CNP-STOICHIOMETRY OF TRANSBOUNDARY RIVERS (DNIESTER, PRUT AND SIRET) AT THE EXIT FROM UKRAINE
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 5, Issue 5
Abstract
For the first time, median stoichiometric ratios of molar concentrations of dissolved inorganic CNP elements were established. For the rivers of the Dniester Basin it is 807С: 49N: 1P, for the rivers of the Prut Basin it is 58N: 1P, for the rivers of the Siret Basin it is 1239C: 69N: 1P. Additionally, the excess of maximum permissible concentrations (MPC) in water used for drinking and household purposes, or for fishing, were not found in the content of most dissolved inorganic compounds of Сarbon, Nitrogen and Phosphorus in the transboundary rivers of the Dniester, Siret and Prut basins at the exit from Ukraine within the boundary of the Chernivtsi region. The exception is the excess of the MPC of nitrites in water used for fishing against the background of the lack of such MPC in water used for drinking and household purposes. The P-deficient growth of phytoplankton was established in the rivers of the Siret basin.
