Dynamics of Nutrients in Aquatic Ecosystems: the Case Study of Ciric Basin River at Nord of Iaşi City
Keywords:
dynamics, nutrients, total nitrogen, phosphorus, Ciric river
Abstract
A 1 year dynamics of two biologically limiting nutrients (N and P) has been carried out in the Ciric basin river at nord of Iasi City. The total nitrogen concentrations varied from 7.55-17.55 mg N/L and total phosphorus concentrations fluctuated between 0.84 and 1.428 mgP/L. According to our experimental data concerning the total nitrogen concentrations, the highest level of pollution is recorded in the spring region of the Ciric brook. The results obtained on the phosphorus content confirm the increase of the pollution degree with carrying phosphorus substances. It is obvious that the waters of Ciric lake rapidly shifted to a hypertrophic status.
