“…The arsenic content of the samples was detected in 69.56 % of the samples and found to be in the range from 0.012 to 0.505 mg/L with an average value of 0.073 mg/L.Arsenic is a naturally occurring element that can be toxic to humans, animals and plants; (Hare et al 2019). Aluminum concentration was analyzed in all samples and ranged from 0.01 to 0.175 mg/L, with an average of 0.014 mg/L.…”

Monitoring the presence of heavy metals in cookware intended for use by both humans and animals is of interest, because of their toxic effects. In this report, a study has been conducted to determine the heavy metals released from 46 items of metallic cookware purchased from a local market in Riyadh. Mn, Fe, Cu, Cr, As, Zn, Ni, Al, Cd and Pb, were analyzed using an inductively coupled plasma-optical emission spectrometer. The order of concentration of essential and toxic elements in all samples showed the following trend: Mn > Al > Pb = As > Fe > Zn > Cu = Ni = Cd > Cr. This study highlighted the importance of the metal release monitoring from cooking utensils in order to protect people from the dangers posed by toxic metals.

“…The obtained values fall far below the action level recommended by FAO/WHO of 0.5 mg/kg (FAO-WHO 2011). Arsenic is a naturally occurring element that can be toxic to humans, animals and plants; however, its toxicity varies, depending on what form it is (Hare et al 2019).…”

The order of concentration of essential and toxic elements in all samples showed the following trend: Mn > Al > Pb = As > Mn > Fe > Zn > Cu = Ni = Cd > Cr. However, the results show that of all the metals released from the cookware and teapots examined in this study were lower than the standard limit suggested by the WHO.

“…Typical encountered minerals in tailings are arsenopyrite (FeAsS), scorodite, (FeAsO 4 ⋅2H 2 O) and arsenian pyrite (As‐rich FeS 2 ) (Wang and Mulligan, 2006; Corriveau et al, 2011). In gold tailings, metals (e.g., Fe, Al, Mn, Cu, Pb, and Zn) can also be associated with As, as well as with clay minerals and oxyanions (e.g., sulfates, phosphates, and carbonates) (Wang and Mulligan, 2006; Hare et al, 2018). Generally, As species from the oxidation of these minerals are predominantly As(V) and, in minor amounts, As(−I) (Campbell and Nordstrom, 2014; DeSisto et al, 2017).…”

“…However, As(III), the most toxic form, is frequently present in moderately reducing conditions or in the presence of organic matter (OM) (Bauer and Blodau, 2006; Wang and Mulligan, 2006). As a note, the toxicity of As species toward humans would vary as follows: As(III) > As(V) > monomethylarsonic acid (MMA) > dimethylarsinic acid (DMA) (Chu and Crawford‐Brown, 2006; Hare et al, 2018). The As threshold toxicity in drinking water is 10 μg L −1 , and greater concentrations can cause human diseases (e.g., skin disorders) and even death to animals such as mammals (Hong et al, 2014; Mandal, 2017; WHO, 2018).…”

“…Amendments consist of mixing tailings with organic or inorganic materials that are used to stabilize the contaminants and to improve the physicochemical (water retention capacity, porosity, and nutrients) and biological properties of tailings (development of the vegetation and microbial growth) (Bolan et al, 2014; Rakotonimaro et al, 2018). Water and soil remediation techniques for As removal from pore water include physicochemical processes (e.g., lime neutralization, fixation on oxides, and vitrification), biological processes (e.g., biomethylation and biomineralization), and plant‐based remediation (Henke and Hutchison, 2009; Komárek et al, 2013; Hare et al, 2018). The use of mixtures with Fe‐based materials is the most common remediation option for As‐contaminated solids, including mine waste.…”

Evaluation of Arsenic Leaching Potential in Gold Mine Tailings Amended with Peat and Mine Drainage Treatment Sludge

et al. 2019

View full text Add to dashboard Cite

Peat and mine drainage treatment sludge can be valorized as amendments on mine sites to stabilize gold mine tailings and reduce the potential leaching of contaminants in pore water. However, the influence of organic amendments on the mobility of metalloids and/or metals in the tailings must be validated, as the leached contaminants may vary according to their type, nature, and origin. The objective of the present study was to evaluate over time the effect of peat‐ and/or Fe‐rich sludge amendments on the mobility of As and metallic cations in the drainage water of tailings potentially producing contaminated neutral drainage. Ten duplicated weathering cell experiments containing tailings alone or amended with peat and/or Fe‐rich sludge (5–10% dry weight) were performed and monitored for 112 d. The results showed that as low as 5% peat amendment would promote As mobility in tailings’ pore water, with As concentrations exceeding Quebec discharge criteria (>0.2 mg L−1). In addition, As(III), the most mobile and toxic form, was predominant with 10% peat, whereas organic species were negligible in all cells. The use of peat alone as organic amendment for the stabilization of tailing contaminants could increase the risk of generating As‐rich contaminated neutral drainage. Conversely, the mix of only 5% Fe‐rich sludge with or without peat decreased As concentrations in leachates by 65 to 80%. Further studies on the use of “peat” or “peat + Fe‐rich sludge” as cover or amendment should be conducted with a focus on Fe/As and Ca/As ratios. Core Ideas Peat amendments enhanced the leaching of As from gold mine tailings. Amendments of 5% peat promoted As(V) leaching, whereas 10% peat increased As(III) leaching. As(III) was predominant at ≥20 mg L−1 dissolved organic C from peat. Mine drainage treatment sludge could decrease As concentrations by 65 to 80% in tailings’ pore water.
