Trace Elements Analysis

Determination of the certain major and trace elements was carried out in drinking water supply scheme in three districts of Meghalaya. This work aims to identify trends resulting in the deterioration of drinking water which is also a potential source of environmental contaminants. About 50 samples, each from one district, were collected both from the source and various tanks and tap. The elements determined are Li, Na, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Ag, Au, Pb, Cd, Se, Ca, K, and Mg. The pH is slightly lower than neutral pH of 7 while the turbidity is very high even after treatment. The concentrations of Ca and Mg are found to be deficient. The elements Cr, Fe, Co, Ni, Zn, Mo, and Pb decrease after treatment while Mn, Cu, and Cd increase slightly after treatment. Se concentration is found to be much higher than expected. The results were compared with the standard recommendation values for the quality of drinking water. This study provides a general indication of where water-quality constituent concentrations met or exceeded water-quality standards and the data presented in this report will be useful from public health point of view.

This work aims to evaluate the quality of drinking water in the communities of Baiacu, Sao Francisco do Conde, Santo Amaro and Cachoeira. It was verified that in some places of Santo Amaro and Sao Francisco do Conde, from the microbiological point of view, it is not appropriate for consumption, because it was found that the presence of total coliforms in 50% of the samples and that the chlorine content is below the values indicated by the standards in 75% of the analyzed samples. Thus, the consumption of contaminated water can cause diseases, so it is recommended cleaning of residential reservoirs, maintenance in pipes periodically, as well as the need for continuous monitoring of water quality and the intense participation of public agencies in these actions. Through these actions and the active participation of the population, one can preserve the environment and the lives of all those who transit in the communities of the Bay of All Saints

Mortality rates of some diseases are affected by water quality. This research examines the roles of two factors related to water quality, namely the quality of drinking water termed ‘water’ and the quality of sanitation termed ‘sanitation’. Two age-related diseases, cardiovascular disease and diabetes (CDD) and chronic respiratory conditions (CRC) are considered while adjusting for personal health issues, environmental and geographical factors. The dataset consists of worldwide mortality rates of adults for the mentioned diseases in 195 countries. These countries are clustered within continents geographically and literature shows the importance of considering the geographical effect of a continent. Furthermore, the two diseases were highly related to each other. Accordingly, the multivariate multilevel model was fitted to the dataset. The results indicated that when the usage of improved drinking water sources and sanitation facilities decreases, the chance of mortality from the two diseases increases. Furthermore, the difference in the risk of the diseases was statistically significant between the continents. It showed that North America and Europe had a lower risk of having CDD and CRC compared to Asia and Oceania. Therefore, the results revealed that the factors ‘water’ and ‘sanitation’ play important roles for this macro geographical variation of CDD and CRC.

Taking into account the problems of ensuring an environmentally safe state of recreation and tourism zones on the territory of Sevastopol, the article presents the results of a study of the water quality of 76 underground springs in the Sevastopol region. The results of the analysis of the obtained data on the chemical composition of spring waters allow us to identify the most polluted sources and track the dynamics of changes in the content of «pollution markers» with the subsequent determination of possible causes of pollution. All sources are divided into three groups: «clean», «relatively clean» and «polluted», the location of which is shown on maps. Studies were conducted on 23 indicators of drinking water quality. The average values of the measured indicators for each category of underground sources under study are presented. In 46% of cases, significant excess of the content of nitrate ions and chlorides in the underground and spring waters of the Sevastopol region was detected, which makes it possible to judge their unsuitability for drinking and agricultural purposes.
