Doctoral student of Samarkand State University Bakhtiyor Aliyev in the scientific laboratory of the Institute of Botany and the Botanical Garden of the Academy of Sciences of the Republic of Uzbekistan conducts scientific research on the topic “pollution of water bodies: determination and assessment of the state of Saprobity”.

    Saprobicity (causing rotting or caused by decomposition) - the ability of water bodies to decompose and the degree of decomposition. Organisms that live in waters with decaying substances are called saprobionts. Decomposition refers to the decomposition of organic matter as a result of the activities of animals and plants in the presence of water with a permanently low oxygen content.

    In sanitary hydrobiology, saprobity refers to the ability of organisms to live with large amounts of organic matter. Saprobicity is a function of the body's needs for organic nutrition and resistance to toxic substances arising from the decomposition of organic substances: H2S, CO2, NH3, H+, organic acids.

    For a quantitative assessment of saprobity, the following are proposed: saprobity indices, species diversity, etc. The difficulties in assessing saprobity lie in the fact that many modern surface waters are polluted not only with organic substances of animal and plant origin, but at the same time with many toxic substances, such as pesticides, oil and oil products, heavy metals, detergents, etc. Biological analysis of the saprobity of a reservoir or part of it is based on the identification of complexes of saprobic organisms proposed by Kolkwitz and Marson, as well as a number of researchers (Zakharov, Nikitinsky, debts, Wetzel, Liebmen, Yadin, Shramek-Gushek, Cyrus, Zelenka, Marwan, Sladechek, etc.), who conducted scientific research in this area, have been studied.
