“…It was established that drinking water contributes to the accumulation of iron in the human body. The water of many groundwater aquifers in Ukraine have a high iron content, which ranges from 0.5 to 30 mg/dm 3 and even more, but more often up it is to 5 mg/dm 3 (Shevchenko et al 2013, Dolina et al 2017, Gomelya et al 2016.…”

Iron is one of the most common components in water that adversely affect humans, other living organisms and parameters of water bodies. Therefore, during using and consuming natural waters, and discharging sewage into surface water bodies, it is necessary to remove iron compounds from the aquatic environment. The use of capillary materials in water purification processes is a promising area of research. Experimental data proved the high efficiency of capillary materials application, providing higher efficiency of iron ions removal from model solutions for real water sources of different origin compared with the traditional method of settling. The main advantage of the application of materials with capillary properties is the simplicity of implementation of the method and there is no need to use electricity and any additional reagents. The effect of various factors on the process of water deironing with the application of capillary materials was studied. It was found out that the density has a little effect on the process at an iron concentration range from 1 to 5 mg/dm 3 . The increase in competing ions content intensifies the process of divalent ferrous ions transition to trivalent. During the deironing of artesian water, the degree of iron removal exceeded 90 %, while the residual concentration was below the MPC.

Purpose. The paper aimed at analyzing the presence of residual quantities of medicinal preparations in the water of Ukraine and the world. Based on the world and own experience to propose methods for waters cleaning from medicines. Methodology. The research was carried out on the basis of analysis of scientific sources and reporting data on the availability of medicines in the water of Ukraine, European countries, the USA (1999-2017). Findings. Analyzed sources inform that the main environmental threat of a global scale is the presence of medicines in drinking water. The treatment facilities are not suitable for the detection and decomposition of medicinal preparations. The fight against these substances is not envisaged all over the world. The authors present the results of a comprehensive review of issues related to the determination of the medicines availability in various waters, their concentrations and the most dangerous medicinal preparations - toxicants. Medications can be accumulated not only in the body of humans and animals, but also in marine and river fish, etc. The impact of even trace amounts of certain medicines (drugs, hormones) can have a negative effect on the health of more vulnerable segments of population, such as children. It was found that the main culprit of hormonal water pollution is agriculture, namely animal husbandry. Originality. The paper summarizes available and presents new methods and technologies for water cleaning, such as: electrochemical, membrane, adsorption based on activated carbon, ultrasonic treatment in the presence of catalysts, treatment of water with enzymes and persulfates. As the second way to reduce the number of medicines in the water, it is proposed to produce environmentally friendly medicines. Practical value. Water problems are the main ones all over the world and in Ukraine as well. It is necessary to provide the additional financing to solve the problem of water cleaning from medicines not on a residual principle, but considering that water is the basis of life on the Earth, and in general the health and life of mankind depends on the quality of water.

Purpose. The main purpose of the article is to analyze the presence of plastic in the water of Ukraine and the world, as well as to suggest the methods for purifying water from plastic on the basis of the world and personal experience. Methodology. The studies were carried out on the basis of the analysis of scholarly domestic and foreign literature sources on the presence of plastic in the water of Ukraine, European countries, and the USA (1999–2018). Findings. The analyzed sources indicate that one of the main environmental threats of global scale is the presence of plastic in drinking and waste waters. The wastewater treatment facilities of the world are not sufficiently adapted to detect and trap plastic. The authors present the results of a comprehensive consideration of the issues related to the determination of the presence of plastic in various waters, their size and concentrations, and manufacturing materials. Plastic, entering the body of people, especially children, animals, sea fish, etc., has a negative influence on their health. Studies have been conducted to determine the content of plastic in drinking tap water in the cities of Dnipro and Zaporozhye. For example, drinking water from the tap contains from 4 to 10 particles of plastic per liter of water, the size of which exceeded 100 microns, that is, the average thickness of a human hair. And in bottled water of well-known trademarks «Morshinska» and «Buvette» contains from 49 to 102 particles of plastic per liter of water. Originality. The paper summarizes the existing and presents new methods and technologies for cleaning water from plastic, such as: filtering on various facilities (mechanical methods), flotation, membranous and reverse-osmotic systems, membrane bioreactors (physical-chemical and combined methods). As a second way to reduce the amount of plastic in water, it is proposed to create biodegradable plastics or prohibit their manufacture. Practical value. Given the prevalence of bottled water consumption worldwide, the results of this study confirm the need for further research on the effects of micro and nanoplastics on human health.
