“…The current study was carried out to provide basic information on fluoride content in groundwater intended for human use. Although a previously published study from the nearby emphasize that the Tuzla Canton faces low fluoride content in drinking water [42], our findings do not confirm it. According to the analysis of 54 drinking groundwater samples, fluoride concentrations ranged from 1.69 to 3.52 mg/L with a mean concentration of 2.44 mg/L (Table 3).…”

“…In addition to India, this problem has been recognized in endemic regions in Iran [46], Pakistan [47], Africa [48], Ukraine [49], where fluoride was found in groundwater samples in concentrations of 1.8 mg/L, 2.0 mg/L, 1.95 mg/L, and 2-7 mg/L, respectively. It is well documented that fluoride present in slightly higher concentrations than recommended can cause various health problems, including endocrine and neurological disorders, renal dysfunction, and health issues with bones and teeth causing skeletal and dental fluorosis [26,[40][41][42][43][44][45][46]. Recent literature reports that fluorosis is a global problem affecting more than 70 million people in 25 countries.…”

Although fluorides are essential for dental health, there are growing health concerns regarding the risk-benefit ratio of fluoride exposure. The objectives of the study were to obtain data on the amount and human health risks of fluoride in drinking groundwater, as well as to compare and evaluate the differences in the outputs obtained by two different approaches in health risk assessment (deterministic vs probabilistic). From a densely populated industrial area of north-eastern Bosnia and Herzegovina, a total of 54 groundwater samples were collected. Fluoride concentrations varied from 1.69 to 3.52 mg/L. The WHO's threshold value for fluoride in drinking water was exceeded in all the samples analysed, indicating an increased daily intake of fluoride from groundwater. Deterministic and semi-probabilistic techniques were used for exposure assessment and health risk quantification. Generally, the deterministic approach resulted in acceptable health risks in most adult exposure scenarios. However, the Monte Carlo simulation revealed that 20.6, 20.8, and 99.8% of adult males, females, and children, respectively, were above the tolerable upper intake level, indicating that both adults and children face a significant health risk. Nevertheless, small children are more vulnerable to environmental hazards than youth and adults. Hence, a more in-depth risk-benefit analysis is required to reduce/or optimize fluoride content in drinking water to prevent tooth decay and fluorosis at all ages. Considering that optimal daily intake of fluorides is a crucial factor for preserving human health, decision-makers should take steps to emphasize the importance of continuous monitoring of fluoride concentrations in drinking water.

“…The measured parameters were phase (at fixed frequency) and amplitude shifts of the sensing line according to the reference one [38]. The precise operating frequency is a ion-selective electrodes [11,12]. Nowadays, research is focused on the development of chemical and biological sensors for chloride sensing.…”

A 104 MHz Surface Acoustic Wave (SAW) sensor functionalized with a 100 nm thick Cobalt Phthalocyanine (CoPc) layer was investigated for chloride sensing in liquid media. Atomic force microscopy was first investigated to characterize the morphology of three phthalocyanine molecules, Pc, CoPc and FePc, deposited by molecular beam epitaxy on the SAW sensing area. CoPc was chosen for its particular columnar shape, highly suitable for sensing applications.Gravimetric results indicate that the Limit of Detection (LOD) of the developed CoPc-SAW sensor was of order of 0.2 µM, and that the corresponding sensitivity was equal to (0.148 ± 0.001) °µM -1 . Recognition and release average time constants were estimated at (45 ± 7) s and (74 ± 4) s respectively.

“…3 Therefore, it is crucial to detect Cl − in drinking water, the environment, and sweat in the current context. Several analytical methods have been documented for Cl − detection, encompassing ion chromatography, 4 electrochemistry, 5 spectrophotometry, 6 and colorimetry. 7 Among these, the spectroscopic procedure involving mercury( ii ) salt is widely adopted and is endorsed by the Association of Official Analytical Chemists as the standard approach for Cl − determination in natural water.…”
