This paper is focused on presenting some ecological and economic aspects related to reconsider water
resources as water capitals, in the forthcoming concept of introducing bioeconomy in the new EU sets of strategies,
policies, and regulations. Financing of this paper is provided by the “Vita Plus” project (2021-2022) – a
transdisciplinary project, executed by researchers of the University of Plovdiv. The object of this paper is to
conduct a research and demonstrate through the “Vita Plus” project complex methods of detecting toxicity in waters.
Furthermore, the focus of the paper is to provide an adequate model for measuring toxicity levels of waters by
conducting reliable toxicology research on fishes from polluted waters. We aimed to set a reliable laboratory
practice, which may be utilized to deliver comparable indicators, as prescribed by EU policies and regulations in the
forthcoming programming period 2021-2027, as there will be a general shift towards circular economy of no to
minimum waste in nature.
