“…However, the removal of heavy metals may require advanced water treatment technologies. Some metals like copper (Cu), zinc (Zn), iron (Fe) and magnesium (Mg) are essential for human growth, but some metals such as cadmium (Cd), chromium (Cr), nickel (Ni), arsenic (As) and lead (Pb) are toxic and harmful to humans (Xie et al 2013).…”

The present study aimed to assess the health risks of chemical contaminants of residents in the coastal areas of Cambodia through their drinking water pathways. Water was sampled from tube wells (n= 22), dug wells (n= 31), ponds (n= 11), canals (n= 12) and lakes (n= 4) across the Cambodian coastal areas, and measured for the contaminants of health concern (As, Cu, Cr, Cd, F−, NO2-, NO3-, Pb, Escherichia coli and total coliform) and aesthetic quality following the United States Environmental Protection Agency (USEPA) and standard methods. Analytical results reveal that 9.1% of tube wells and 9.7% of dug wells contained As > 0.01 mg/L. Appropriately, 22.7% of tube wells and 32.3% of dug wells contained Fe > 0.3 mg/L while 100% of tube wells and 80.6% of dug wells contained Mn > 0.1 mg/L. Health risk assessment found that the hazard quotient (HQ) > 1 for children and women. Additionally, the lifetime cancer risk (LCR) was found >1 × 10−4 for As in Cambodian coastal areas. Therefore, a monitoring programme and appropriate treatment to remove contaminants like arsenic, cadmium and fluoride would be required to ensure a safe drinking water supply to Cambodian coastal residents.

This study investigates the modifications in the physicochemical properties of natural mineral waters induced by microwave radiation and agitation. Mineral waters from Svyatoi Istochnik, Aqua Minerale, Karachinskaya, Arkhyz, and Serebrianyi Kliuch were subjected to these two activation methods. The pH and redox potential parameters were meticulously evaluated to observe alterations. Experimental studies provide evidence that microwave radiation and agitation significantly alter the physical and chemical characteristics of the selected mineral waters. A standard microwave oven operating at a frequency of 2.45 GHz was utilized for microwave radiation while agitation was performed using established techniques. The changes in pH and redox potential were carefully measured post-treatment. Technologically significant properties of the treated water were identified. These include a reduction in acidity due to an increase in pH value and a near tripling of the water's redox potential following a total stirring time of 2 minutes compared to an untreated control sample. The mechanochemical technique employed during agitation caused water molecule destruction due to friction forces, plastic deformation, impact compression, and mass transfer intensification. Conversely, the microwave radiation effect is attributed to the resonance effect resulting from the absorption of microwaves by water molecules. Moreover, it was experimentally determined that the activation effect of agitation persisted in the mineral waters for one hour, while the effect of microwave radiation lasted for one day. This longevity indicates a more profound influence of microwaves on the electronic systems of the water's components. In conclusion, the study demonstrates the feasibility of altering the physicochemical parameters of mineral waters with varying compositions and degrees of mineralization using short-term microwave radiation and agitation. The successful modification of the water samples' hydrogen index and redox potential signifies the potential utility of these techniques in manipulating the properties of mineral water.

Physicians as the First Analytical Chemists: Gall Nut Extract Determination of Iron Ion (Fe²⁺) Concentration

et al. 2018

Many students enroll in college general chemistry with an interest in a medical career. In those (and alternative) careers, they will need to make critical decisions about data and how that data are acquired. A significant portion of introductory lab experiments are, in principle, but not necessarily in practice, devoted to understanding how chemical information is gained and how it is deemed reliable. Here we report on a laboratory experiment that is presented as a guided inquiry investigation grounded in the history of science and the link between early medicine and quantitative data. Oak gall extract is used to quantitatively determine the amount of iron present in a water sample using UV−vis absorbance. In this experiment, students are introduced to the Beer−Lambert law, calibration curves, and the reading of UV−vis spectra
