“…Iron is the third abundant element in the earth's crust ( Taylor, 1964 ), and it can be found in high amounts in soil and water. The major anthropogenic sources of iron contaminations are industrial wastes, urban wastes/sewage, agricultural and mining activities ( Hasan et al., 2019 ). As summarized in Table 2 , the mean concentrations of Fe measured in the Akaki-Kality Sub-City were lower than most of the reported values for drinking water from Iran ( Fallahzadeh et al., 2017 ), India ( Gupta et al., 2017 ; Vetrimurugan et al., 2017 ), Pakistan ( Khalid et al., 2020 ; Rasool et al., 2016 ) and Canada ( Hu et al., 2019 ), but higher than the reported values from Iran ( Saleh et al., 2019 ) and Nigeria ( Egbueri and Unigwe, 2020 ).…”

“…However, the level of Zn in this study was found to be higher than the value reported by other researchers from Iran ( Saleh et al., 2019 ), India ( Vetrimurugan et al., 2017 ), Pakistan ( Khalid et al., 2020 ), Nigeria ( Egbueri and Unigwe, 2020 ). Even if Zn is essential for our body, excess Zn in the body can cause diarrhea, vomiting, and neurological damage ( Hasan et al., 2019 ; Izah et al., 2016 ).…”

Water is an essential component of all living things on earth and the contamination of water by heavy metals can cause detrimental health effects. This study aimed to determine the health risk posed by trace elements (Fe, Zn, Cu, Mn, Ni, Cr, Cd, Co, Pb, and As) present in the drinking water supplies of Gullele and Akaki-Kality Sub-Cities, upstream and downstream parts of Addis Ababa, respectively. The concentrations of the potentially toxic trace elements in the water samples were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES). The highest concentration of the heavy metals was observed for Iron. Cadmium and cobalt were not detected in any of the tap water samples. Samples from Gullele contained higher levels of Fe and Mn, 220.3 ± 0.17 and 19.78 ± 0.08 μg/L, respectively compared to Akaki-Kality, 38.87 ± 0.14 and 2.08 ± 0.01 μg/L, respectively. Conversely, tap water from Akaki-Kality contained significantly higher levels of As than that from Gullele. Additionally, Cr and Ni were detected only in samples from Akaki-Kality, which might be due to the various industries in the area. The highest incremental lifetime cancer risk was found for arsenic, with values for children and adults in Akaki-Kality 2.50 × 10 −4 and 4.50 × 10 −4 , respectively. Likewise, in Gullele Sub-City, it was 5.00 × 10 −5 and 1.00 × 10 −4 for adults and children, respectively. The results indicate that carcinogenic risk occurrence is probable from As in both studied areas.

“…In Dhaka, Bangladesh, tanneries are a priority economic growth sector and leather is a major export [16]. However, wastewater discharged from the hundreds of local tanneries is a major source of air and surface water contamination in the region [17], and of high exposure to heavy metals and other chemicals among workers and local residents [18]. Often historically overlooked in the development-environment equation are the health and welfare impacts of pollution [19], which can themselves impose very large economic and social costs [20].…”

Background: As low-and middle-income countries urbanize and industrialize, they must also cope with pollution emitted from diverse sources. Main text: Strong and consistent evidence associates exposure to air pollution and lead with increased risk of cardiovascular disease occurrence and death. Further, increasing evidence, mostly from high-income countries, indicates that exposure to noise and to both high and low temperatures may also increase cardiovascular risk. There is considerably less research on the cardiovascular impacts of environmental conditions in low-and middleincome countries (LMICs), where the levels of pollution are often higher and the types and sources of pollution markedly different from those in higher-income settings. However, as such evidence gathers, actions to reduce exposures to pollution in low-and middle-income countries are warranted, not least because such exposures are very high. Cities, where pollution, populations, and other cardiovascular risk factors are most concentrated, may be best suited to reduce the cardiovascular burden in LMICs by applying environmental standards and policies to mitigate pollution and by implementing interventions that target the most vulnerable. The physical environment of cities can be improved though municipal processes, including infrastructure development, energy and transportation planning, and public health actions. Local regulations can incentivize or inhibit the polluting behaviors of industries and individuals. Environmental monitoring can be combined with public health warning systems and publicly available exposure maps to inform residents of environmental hazards and encourage the adoption of pollution-avoiding behaviors. Targeted individual or neighborhood interventions that identify and treat high-risk populations (e.g., lead mitigation, portable air cleaners, and preventative medications) can also be leveraged in the very near term. Research will play a key role in evaluating whether these approaches achieve their intended benefits, and whether these benefits reach the most vulnerable. Conclusion: Cities in LMICs can play a defining role in global health and cardiovascular disease prevention in the next several decades, as they are well poised to develop innovative, multisectoral approaches to pollution mitigation, while also protecting the most vulnerable.

“…Adverse reproductive outcomes as a result of these exposures includes spontaneous abortions, fetal birth defects, stillbirths, preterm birth, problems with early emotional development, and neonatal death. [42][43][44][45][46][47] In studies done on pregnant Sprague Dawley rats, Banu et al 48 While Cr(VI) exposure may have been the driving force behind the toxicity observed in our studies when cells were exposed to GMAW-SS or SMAW-SS, welders are exposed to a combination of heavy metals in the workplace. In trophoblasts exposed to GMAW-MS, which is primarily composed of Fe and Mn, significant decreases in cellular viability and invasion capabilities at 24 hours when compared to controls, along with the significant production of • OH and intracellular ROS, was still observed.…”

“…In women exposed to Cr at the worksite, epidemiological data have shown that these workers have elevated levels of Cr in their blood, urine, umbilical cord, and placental tissue. Adverse reproductive outcomes as a result of these exposures includes spontaneous abortions, fetal birth defects, stillbirths, preterm birth, problems with early emotional development, and neonatal death . In studies done on pregnant Sprague Dawley rats, Banu et al found that exposure to Cr(VI) through drinking water led to increased apoptosis in trophoblast cells, as well in the epithelium of the mesometrial triangle vessels and of the yolk sac epithelium via the induction of caspase‐3‐ and p53‐dependent pathways.…”

Problem As more women join the skilled‐trade workforce, the effects of workplace exposures on pregnancy need to be explored. This study aims to identify the effects of mild steel and stainless steel welding fume exposures on cultured placental trophoblast cells. Method of study Welding fumes (mild steel and stainless steel) were generously donated by Lincoln Electric. Electron microscopy was used to characterize welding fume particle size and the ability of particles to enter extravillous trophoblast cells (HTR‐8/SVneo). Cellular viability, free radical production, cytokine production, and ability of cells to maintain invasive properties were analyzed, respectively, by WST‐1, electron paramagnetic resonance, DCFH‐DA, V‐plex MULTI‐SPOT assay system, and a matrix gel invasion assay. Results For all three welding fume types, average particle size was <210 nm. HTR‐8/SVneo cells internalized welding particles, and nuclear condensation was observed. Cellular viability was significantly decreased at the high dose of 100 µg/mL for all three welding fumes, and stainless steel generated the greatest production of the hydroxyl radical, and intracellular reactive oxygen species. Production of the cytokines IL‐1β and TNFα were not observed in response to welding fume exposure, but IL‐6 and IL‐8 were. Finally, the invasive capability of cells was decreased upon exposure to both mild steel and stainless steel welding fumes. Conclusion Welding fumes are cytotoxic to extravillous trophoblasts, as is evident by the production of free radicals, pro‐inflammatory cytokines, and the observed decrease in invasive capabilities.
