Analysis of water samples has shown for the majority of the examined sources that the permissible concentrations are exceeded in many parameters of the chemical composition. Permanent use of water from these sources can be one of the health hazards for the local population....
Chemical composition of drinking water was examined in rural settlements of Bryansk region to reveal its influence on distribution of endemic thyroid diseases among population after the Chernobyl accident (1986) with due regard to different sources of water, the age and composition of water-bearing ...
Prevalence of diabetes mellitus and hypertension in relation to chemical composition of drinking water: Does magnesium protect against diabetes mellitus? 来自 NCBI 喜欢 0 阅读量: 17 作者:Y Adi,H Mahaba 摘要: Full text is available as a scanned copy of the original print version....
We conducted experiments with typical surface water with HS. The results show that u.v.-radiation of humus water changes the chemical composition of water, including acidity and charge density and also inhibits the growth of the alga Selenastrum capricornutum. Inhibition increases with increased "u....

The chemical composition of rainfall changes slightly as clouds move. Most hydrogen and oxygen atoms in water are stable but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid(列阵)falls first. As a result storms that form over the Pacific deliver heavier...
Aim: This study was carried out to assess caries Prevalence as well as the most effective factors in a group 0: school children aged 8 years in Tehran during 1999-2000.Materials and Methods: A total number of 1024 children were randomly selected. The level of Fluoride drinking water was ass...

Inorganic compounds dissolved in water are released from rocks by weathering processes and distributed by water.Therefore,the quality of surface-and groundwater is-besides the influence of temperature and the composition of precipitation-particularly governed by the kind of rocks outcropping in an area....
Chemical compositionREELake dynamicsStable isotopesVolcanic contaminantsVolcanic lakes carry fluids that range from ultra acid, high TDS brines to largely meteoric fluids. Their water compositions are governed by volcanic fluid inputs, which range from almost raw, cooled volcanic gases (largely S–Cl–...
