The article examines the chemical pollution of the Iori River, one of the most important rivers in Georgia. In addition to Georgia, this river is found in Azerbaijan. The study of this river is crucial as LLC United Water Supply Company of Georgia organizes the water supply of big cities and villages of Georgia through Iori water. Furthermore, the population of two big villages independently uses the river water for various household activities: washing (laundry, products, dishware), livestock watering, and irrigation. They do not use it as drinking water. The water of the Iori River was monitored in two sections: village Sasadilo and village Sartichala. In total, 24 samples were taken over the course of 2018 and 2019 years. Some part of the research was conducted on the site through HI83399-02 | Water Wastewater Multiparameter (with COD) Photometer and pH meter device. These studies included pH, BOD, and the temperature was measured directly during sampling. The same device was used for measuring approximate concentrations of heavy metals. At the next stage of the study, an inhabitants survey was conducted to identify their knowledge of environmental cleanliness and safety concerns. As a result of the study, our recommendation to the population is to refrain or restrict the use of untreated river water directly in domesticities. The results of the survey showed that the population has less information about the likelihood of getting heavy metals in the body and developing tumor diseases.

Abstract A chromatographic-colorimetric method has been developed for the determination of trace amounts of polyvinylpyrrolidone (PVP) and its copolymers in foods, beverages, laundry products, and cosmetics. Products containing the PVP are passed through a chromatographic column and the PVP is adsorbed at the top of the column. The column is prepared from silica gel if the sample is soluble in 40% acetic acid solution while Micro-Cel E is used when the sample is soluble in a 50% ethanol solution. The PVP adsorbed on the column is then treated with Vital Red dye and the PVP-dye complex thus formed is eluted with TV-methyl pyrrolidone and measured colorimetrically. From the data obtained it is apparent that the method can detect as little as 0.1 ppm with a reproducibility of ±5% of the amount present.
