“…Human health risk assessment involves estimating and quantifying the probability of occurrence of an event and the magnitude of its effect on health with a given exposure over a defined period. To this end, the United States Environmental Protection Agency (US EPA) has proposed a human health risk assessment model [25] widely used worldwide [26][27][28][29][30][31] which is based on four steps as follows: hazard identification, exposure assessment, response to a certain dose, and risk characterization [26].…”

“…The ingestion route and dermal contact were considered for estimating the exposure of the local population. The average daily doses from ingestion (ADD ing ) and dermal absorption (ADD dermal ) of a pollutant via water as the exposure pathways are expressed in (µg/kg/day) and were estimated by the following equations [26,28,29,31,33]:…”

“…Evaluating health risk by investigating some of the anions and toxic metals in water is essential to determine the probable illnesses caused by drinking water and to protect public health as well; this risk assessment is being carried out all around the world [1,3,7,8,10,15,19]. The most commonly applied methods are chronic daily intake, hazard quotient, and total carcinogenic risk [19,[25][26][27][28][29][30][31][32][33][34]. Human health risk assessment is defined by the United States Environmental Protection Agency (US EPA) [25] as a systematic approach to assess the potential health effects of exposure to certain harmful substances that are present in polluted environmental media [25,26].…”

This research aims to assess the content of some ions and trace elements in water sources in 24 rural Roma communities in Transylvania in order to assess the human health risk associated with exposure to such elements and ions. To this end, eight ions (F−, Cl−, Br−, NO2−, NO3−, SO42−, PO43−, NH4+) and ten trace elements (Cr, Ni, As, Pb, Cd, Mn, Cu, Zn, Fe, and Hg) were determined in 71 water samples by ion chromatography coupled with a conductivity detector for ions and atomic absorption spectrophotometry for all trace elements. General parameters were also determined. Non-conformity (as number of samples), according to the EU Drinking Water Directive, was observed as follows: pH (7), EC (7), hardness (1), oxidizability (15), Cl− (4), NO3− (30), SO42− (6), Fe (16), Mn (14), As (3), and Ni (1 sample). The incidence of ions was Cl− (71), SO42− (70), F− (67), NO3− (65), NH4+ (21), Br− (10), PO43−, and NO2− (1 sample) and for trace elements, Mn (59), Fe (50), As (38), Ni (32), Cu (29), Zn (28), Cd (12), Cr (11), and Pb (3 samples). Hg was not detected. Non-carcinogenic (HI) values exceeded one for As in 13 Roma communities, with higher values for children than for adults. For NO3−, the HI values were >1 in 12 for adults and 14 communities for children. The carcinogenic risk (CR) for As through ingestion ranged from 0.795 to 3.50 × 10−4 for adults and from 1.215 to 5.30 × 10−4 for children. CR by dermal contact was in the range of ×10−6 both for adults and children.

Nitrate is one of the most widespread water contaminants globally. Nitrate levels in groundwater and surface water can rise to unhealthy levels as a result of nitrogen fertilizer runoff from lawns and farms. This research aims to selectively convert nitrate to gaseous nitrogen using Palladium‐Tin (Pd‐Sn) bimetallic electrodes electrodeposited on stainless‐steel (SS). Inductively coupled plasma optical emission spectrometry, scanning electron microscope, and X‐ray diffraction are used to analyze the composition, surface morphology, and crystal structure of the electrodes. The XRD analysis reveals that the Pd‐Sn/SS electrode has a crystalline nature when a Pd molar ratio >0.5 while an amorphous phase is detected over a Pd molar ratio (≤0.5). The electrochemical nitrate reduction is carried out in a 0.1 M HClO4 / 8 mM NaNO3 solution for 5 h using electrodes prepared in deep eutectic solvent (DES) system. The Pd0.93Sn0.07/SS electrode shows the best catalytic performance in terms of high nitrate conversion of 97%, N2 selectivity of 88%, and N2 yield of 86% compared to counter electrodes. These findings demonstrate a considerable impact of the electrode preparation process on nitrogen conversion, selectivity, and yield.
