“…Such approaches allow to identify not only gaps in the studied subject, but also some particular aspects of the problem that might not have come to the scholars' attention for one reason or another. In general, this gives the opportunity to objectively compare these aspects and, on their basis, determine the prospects for further research (Alimbaev et al, 2021).…”

Concentrations of heavy metals such as As, Fe, and Mn in ground water from the Red River and Mekong River Deltas were exceed than WHO drinking water guidelines, putting at risk the millions of Vietnamese people relying on groundwater in these regions as sources of drinking water. This situation suggests solution for drinking water suppliers together with efficient water treatment technologies for groundwater or alternative drinking water sources such as surface water or tap water. Vietnam has an expanding population and growing economy, and is undergoing rapid industrialization and urbanization. It is of the utmost importance that good strategies be developed for the management of safe drinking water for both public and private supply, in the cities as well as the countryside. Educating residents of rural areas to understand the effects of contaminated drinking water on their health is essential. A long-term water quality monitoring program with more frequent testing should also be considered. In Vietnam, groundwater is obtained primarily from tubewells, which have high concentrations of pollutants such as As, Fe, Mn, and NH 4 + . In the areas where groundwater tests were conducted, arsenic levels ranged from 0.1-3050 μg/L, which substantially exceed the standard of 10 μg/L which has been established by the WHO. Contamination sources are distributed over a large area from the Red River Delta in the north to the Mekong River Delta in the south, putting as many as ten million people at risk of adverse health effects. Levels of arsenic and iron in sediment are strongly correlated, which indicate that the presence of arsenic in groundwater results from the reduction of arsenic bound to iron oxyhydroxides. It is important to raise awareness of these issues among the Vietnamese public by disseminating information about the negative effects of contaminated drinking water, as well as carrying out long-term research projects to identify other sources of contamination and improving water treatment technology and water management capabilities.

“…The tables provide data on sources of heavy metals, permitted concentrations, toxic effects, removal efficiency over a specified time period, removal capacity (generally in mg pollutant/g treatment technology), advantages and disadvantages of each method. In general, this allows for an objective comparison of these methods and, on that basis, determining the prospects for future studies (Alimbaev et al, 2021).…”

Industrial wastewater has become a major problem due to high concentration of numerous harmful and hazardous pollutants, particularly heavy metals (HMs). Heavy metal pollution and its consequences for human health and the environment have increased interest in developing low-cost, long-term remediation technology. To remove heavy metals, various conventional physicochemical and green biological methods are used. This review article examines both conventional and biotechnological approaches for removing HMs from wastewater and rates their efficiency. The most appropriate technique for removing heavy ions from wastewater is determined by a number of factors, including operation cost, initial metal ion concentration, environmental impact, pH values, chemicals added, removal efficiency, and economic feasibility. These methods include adsorption treatments using various adsorbents, membrane treatments, chemical treatments, electric treatments i.e. electrochemical treatments. In general, chemical, adsorption, and membrane methods are the most practical method addressed in the literature. It has been noticed that there is a clear knowledge gap in the performance of treatment methods for the removal of heavy metal ions from real wastewater because most studies used synthetic wastewater in which one or few metal types are present. Accordingly, additional research should be conducted using real wastewater for treating different contaminants. More research on introducing cost-effective materials and methods for heavy metal removal from wastewater should be carried out. The best techniques for recovering metals with minimal environmental impact and low cost are still being developed and should be considered in future research.

Once one of the largest saline lakes, the Aral Sea, was recognized as a significant environmental disaster as the water level decreased dramatically. Water level decrease increases water salinity, affecting biodiversity. Exposed lake beds become the source for fine dust picked up by the dust storms and spread across a long distance, affecting people’s health in surrounding areas. This review paper attempts to evaluate the potential links between the Aral Sea shrinking and the existing health issues in the case of Kazakhstan. The literature-based research revealed that the population of the Aral Sea basin region has been suffering from exposure to various pollutant residues for a long time. There is an apparent increase in morbidity and mortality rates in the region, especially in people suffering from chronic illness. Furthermore, the catastrophic desiccation of the Aral Sea has led to the sharp deterioration in living conditions and negative trends in the socio-economic situation of the region’s population. While the dust storms spread the polluted salts from the exposed bottom across the Aral Sea region, specific contaminants define the relevance and importance of public health problems linked to the basin rather than the Aral Sea drying process. There is, however, no clear evidence that associated dust storms are the only primary source of the deterioration of people’s health. Moreover, One Health approach seems to play a crucial role in achieving better outcomes in the health of people and the health of the environment.
