Investigation of factors of the appearance of odor in river water at the water intake of Rostov-On-Don

Abstract

The paper presents a study of quality of natural waters and water in a centralized water supply system during the period of an increase in the “Smell” indicator in the spring of 2021. The chemical and physical properties of water, the results of quality and quantity of studying the variety I phytoplankton in the most difficult period of deterioration in quality of river water. Low water and exceeding MPC concentrations of organic substances in river water. The Don River causes altered form odorant substance as evidenced by the results of determination in water 1,2,3- t rihlorbenzol and geosmin, hexachloroethane and aniline shown in operation. Barrier function of reagent treatment methods used at water treatment plants in the lower reaches of the river. The Don River, even when combined with carbonated water, is deficient in odor-producing substances.

Molecularly Imprinted Heterostructure-Based Electrochemosensor for Ultratrace and Precise Detection of 2-Methylisoborneol in Water

“…Unpleasant water odor episodes frequently occurred worldwide, − of which earthy/musty odors are most widely reported and generally attributed to the release of 2-methylisoborneol (2-MIB) and geosmin by cyanobacteria or actinomycetes. − In the last decades, occurrence of 2-MIB and geosmin in source water or drinking water was reported all over the world from time to time, , and 2-MIB occupied more than 50% for the earthy/musty odor episodes . High concentrations of 2-MIB in water sources pose potential health hazards and serve as indicators of the presence of algal toxins in water. , Currently, 2-MIB is strictly regulated in drinking water at no more than 10 ng/L in many countries/areas. , Due to the low concentrations and thresholds, its accurate and convenient determination is rather challenging.…”
