“…However, the windmill water samples recorded a slightly lower pH of 7.18, further indicating that the water of the study area consists of neutral conditions. The pH of both the tap and windmill water samples indicated that the water was characterised of weak acidic conditions to weak basic conditions [24]. In Zakir et al [25], neutral pH values were associated with high amounts of Ca, Mg and Na ions in water, which is also the case for the water of the current study.…”

“…Furthermore, As, Cr, Tl, Sb and V CDI values exceeded the corresponding RfD value, while that of other trace elements were within their RfD limits set by the United States Environmental Protection Agency [39]. An RfD value is the estimated value per day of exposure of a certain metal to the human body that has no hazardous effect during a lifetime [24]. Therefore, As, Cr, Tl, Sb and V pose serious health threats to the community of the study area due to their CDI values exceeding the RfD value.…”

Contamination of drinking water by metals remains a global threat to living organisms. Therefore, the current study describes variations of metal occurrence, water quality and human health risk assessment between the dry and wet seasons of a rural village located in the Eastern Cape Province, South Africa. The concentrations of major and trace metals were determined in drinking water samples using inductively coupled plasma-optical emission spectrometry (ICP-OES). The physicochemical parameters, water quality index (WQI), total water hardness (TWH) and health risk assessment (hazard quotient: HQ and chronic daily intake: CDI) were evaluated seasonally. The TWH results showed that the water was very hard with water hardness values ranging between 415 and 442. The water also contained several metals and metalloids such as Al (2.18–3.36 mg L−1), As (0.17–0. 53 mg L−1), Cd (0.0068–0.0134 mg L−1), Cr (0.2481–0.2601 mg L−1), Mn (0.387–1.582 mg L−1), Pb (0.064–0.0802 mg L−1), Sb (0.0496–0.1391 mg L−1) and Se (0.075–0.148 mg L−1) that exceeded the SANS and WHO permissible limits in drinking water. The health risk assessment revealed that the water may cause noncarcinogenic and carcinogenic health effects due to the presence of As, Cr, Sb, Tl and V in water samples, while the water quality index revealed that the water was of very poor quality.

“…The potential health risk from exposure of several metals in rice grains (HI) was calculated according to the EPA guides for health risk assessment (Ogunkunle et al 2016) using the following equation: HI = ΣHRI= HRICd + HRINi + HRIPb + HRICu + HRIMn + HRIZn (9) For the Health Risk Index (HRI) and Harzard Index (HI) calculations, the three metallurgical wastes (Metallurgical press residue; FPM: Filter press mud; PM: Phosphate mud) were considered at 8 t ha -1 dose.…”

“…The translocation capacity varies with plants species and with the PTE's (Bonanno et al 2018). Plants with greater translocation factor can jeopardize food security when cultivated in soils contaminated with PTE's (Khan et al 2017;Antoniadis et al 2017), especially when translocation is toward the consumable plant' part such as grain or leafy vegetables (Sihlahla et al 2019). Some PTE's, such as Pb and Cd, did not show any bene cial role in plants or animals (Zul qar et al 2019) and in order to estimate risks of oral exposure, health hazards are calculated using indexes that consider a reference dose (RfD) as a dose of daily oral exposure for the human population that does not cause deleterious effects throughout life (Peng et al 2018;Chen et al 2018;Halder et al 2019;Shahriar et al 2020).…”

Potentially toxic elements (PTE’s) are of great concern in steel mill wastes. Therefore, in other to use them as potential fertilizers in soil, risk assessments are needed. Three steel mill wastes were tested as possible amendments for soils at six different doses (0; 0,5; 1; 2; 4; 8; 16 t ha-1): Phosphate mud (PM), Metallurgical press residue (MPR) and Filter press mud (FPM) during rice cultivation in a pot experiment in a Haplic Gleisol. Analysis on rice tissues, including roots, shoots, husk and grains were conducted and contents of Cu, Cd, Ni, Zn, Mn and Pb were assessed. Translocation and bioaccumulation factors were calculated for each element. In general, PTE’s are more accumulated in roots and greater contents of Zn and Mn were found, while the lowest ones were found for Pb, probably due to its lack of functional roles during plants development. Higher translocation was observed for Mn, which is associated to the redox conditions of rice cultivation and the high mobility of this element under this condition. Application of steel mill wastes can increase PTE’s bioavailability and translocation factors, especially PM, but all of the wastes reveal a high hazard index.

“…At the same time, the discharges from the increased chemical processes, agricultural processes, and energy conversions, amongst other applications, have elevated water pollution. These anthropogenic processes have been observed to be the major contributors to the elevated concentrations of trace metals in water bodies [ 2 , 3 , 4 , 5 , 6 ]. The statistics published by the World Health Organization (WHO), based on the 2017 figures, pronounce that 785 million people lack basic drinking-water services, including 144 million people who are dependent on surface water.…”

The elevated concentrations of various trace metals beyond existing guideline recommendations in water bodies have promoted research on the development of various electrochemical nanosensors for the trace metals’ early detection. Inspired by the exciting physical and chemical properties of nanomaterials, advanced functional nanocomposites with improved sensitivity, sensitivity and stability, amongst other performance parameters, have been synthesized, characterized, and applied on the detection of various trace metals in water matrices. Nanocomposites have been perceived as a solution to address a critical challenge of distinct nanomaterials that are limited by agglomerations, structure stacking leading to aggregations, low conductivity, and limited porous structure for electrolyte access, amongst others. In the past few years, much effort has been dedicated to the development of various nanocomposites such as; electrochemical nanosensors for the detection of trace metals in water matrices. Herein, the recent progress on the development of nanocomposites classified according to their structure as carbon nanocomposites, metallic nanocomposites, and metal oxide/hydroxide nanocomposites is summarized, alongside their application as electrochemical nanosensors for trace metals detection in water matrices. Some perspectives on the development of smart electrochemical nanosensors are also introduced.
