“…In addition, a higher pH in the present study is subjected to enhance calcite mineral precipitation (Dahiphale et al, 2020). Additionally, Ca 2+ , Mg 2+ , and HCO 3 − were also highly observed in the present study, which could be released from dissolution containing calcium magnesium carbonate, ideally CaMg-(CO 3 ) 2, and carbonate-containing minerals or could result from atmospheric deposition of CO 2 with rainwater (Ismail et al, 2018;Natasha et al, 2021). Moreover, calcite dissolution could derive from cretaceous calcareous and Jurassic sandstone (Zhang et al, 2021).…”

“…The groundwater table depth in the Ghotki area varies between 1.48 and 16.2 m, with an average of 5.24 m. While the water table depth in the Nawab Shah area varies between 1.39 and 15.4 m, with an average of 5.10 m. The groundwater samples were filtered through a filtration process on-site using a 0.45 μm membrane. All the groundwater samples were collected in two sets of polyethylene 1.5 L plastic bottles after filtration, following the procedure adopted by Natasha et al (2021). To avoid any kind of contamination from the pipes, water was continuously purged and pumped for 4-6 min through the taps before the groundwater samples were collected, this procedure was adopted by Tabassum et al (2019).…”

“…Various geo-statistical approaches and multivariate statistical analysis have been implied to comprehensively understand the geochemistry of groundwater, spatial distribution of contaminants level, water quality index, and health risk assessment in many developing countries (Singh et al, 2011a;Singh et al, 2011b;Avtar et al, 2013;Dehghanzadeh et al, 2015). For instance, nitrate, fluoride, and arsenic were frequently recorded as the main contributors to groundwater contamination worldwide (Zhang Q. et al, 2020;Adimalla 2021;Natasha et al, 2021;Mwiathi et al, 2022). Research work has been conducted in the past, concerning groundwater quality and its hydrochemistry worldwide (Huang et al, 2018a; van Geen et al, 2019;Kumar and Singh 2020;Mallick et al, 2021a;Mallick et al, 2021b;Dashora et al, 2022;Khattak et al, 2022).…”

Arsenic (As) contamination in drinking groundwater sources is a common environmental problem in Pakistan. Therefore, we collected a total of (n = 81) drinking groundwater samples from various groundwater sources, from two districts’ namely Ghotki (n = 44) and Nawab Shah (n = 37) of Sindh, Province, Pakistan. The current research aimed to investigate the hydrogeochemistry of groundwater with elevated arsenic (As), its effect on the health of local population living in the study area, potential sources of groundwater variables, and the suitability of groundwater for ingestion motive. The results showed that groundwater sample variables of both districts had moderate to high concentration levels. The cations concentrations were observed in decreasing order of Na+ > Ca+ > Mg+ > K+, for both districts, while anions abundance was HCO3− > Cl− > SO42− > F− > NO3− in the Ghotki, and HCO3− > SO42− > Cl− > NO3− > F− in the Nawab Shah, respectively. Arsenic (As) had low to high concentration levels in both districts, observed with average values of 10.1 μg/L and 21.0 μg/L in the Ghotki and Nawab Shah, respectively. The water type was mixed CaMgCl type in both districts, while the groundwater sources were saturated for CO3 minerals indicated by the saturation indices results. Principal component analysis showed the geogenic source of ion exchange, dissolution of minerals, weathering of host rocks and anthropogenic input of industrial activities, agricultural practices and domestic waste for groundwater contamination. The water quality index (WQI) exhibits that majority of groundwater samples (73.6% of Ghotki and 65.7% of Nawab Shah) were suitable for drinking. The non-carcinogenic risk (HQ) values of As were (>1) in groundwater samples of the Ghotki and Nawab Shah, while a high mean HQ value (8.78 × 100) was recorded for children in Nawab Shah. The carcinogenic risk (CR) values of As were significantly higher than the maximum threshold CR value (1 × 10–4). This study emphasized that monitoring strategies are substantially needed to mitigate the As contamination to reduce the potential health risk.

Lead (Pb) is a pervasive contaminant and poses a serious threat to living beings. The present study aims at batch and fixed bed column scale potential of commercial compost (CCB) and peanut shells biosorbents (PSB) for the sequestration of Pb from contaminated aqueous systems. The PSB and CCB were characterized with FTIR, SEM and Brunauer Emmett-Teller (BET) to get insight of the adsorption behavior of both materials. Fixed bed column scale experiments were performed at steady state flow (2.5 and 5.0 mL/min), initial Pb concentrations (25 and 50 mg/L) and dosage of each adsorbent (3.0 and 6.0 g/column). Columns packed (15.9 cm2) with PSB and CCB have revealed excellent adsorption of Pb with PSB as compared with CCB. The total volume of injected contaminated water was 1,500 mL and 3,000 mL at 2.5 and 5.0 mL/min, respectively while total bed volume number was 157. A series of batch experiments with CCB and PSB was conducted at adsorbent dosage (1.25–5.0 g/L), initial Pb level (25–100 mg/L), interaction time (0–180 min) and solution pH (4–10) at room temperature. Batch scale results revealed that PSB removed 92% Pb from water at 25 mg Pb/L concentration as compared with CCB (79%). The presence of competing ions in groundwater showed less Pb removal as compared with synthetic water. The experimental data were simulated with equilibrium isothermal models: Langmuir, Freundlich, and kinetic models: pseudo first order, pseudo second order and intra-particle diffusion. The Freundlich and pseudo second order models better described the equilibrium and kinetic experimental data, respectively with maximum sorption of 42.5 mg/g by PSB which is also evident from FTIR functional groups and SEM results. While equilibrium sorption of Pb onto CCB was equally explained by Freundlich and Langmuir models. These findings indicate that PSB could be an active and ecofriendly biosorbent for the sequestration of metals from contaminated aqueous systems.

“…Contaminated agricultural soils with toxic metals occur mainly through human activities such as mining, waste disposal, irrigation with wastewater, and application of inorganic and organic fertilizers to agricultural land (Xiao et al 2019). Previous studies have discovered that crops cultivated in soils polluted with toxic metal(loid)s, e.g., cadmium (Cd), lead (Pb), and arsenic (As), could uptake high concentration of metal(loid)s by roots and accumulate them in their tissues (Gan et al 2017;Hussain et al 2021;Li et al 2020;Natasha et al 2021;Wen et al 2021). Both Cd and Pb are extremely harmful toxic metals with high mobility in soil-plant environmental system (Jing et al 2019;Qin et al 2020).…”

The current study investigated the effect of biochars derived from cinnamomum woodchip, garden waste and mulberry woodchip on soil phytoavailable lead (Pb), cadmium (Cd) pools, and their uptake by Chinese cabbage (Brassica chinensis L.). The biochars were produced at 450 °C of pyrolysis temperature. The contaminated soils were collected from Yunfu (classified as Udept), Jiyuan (Ustalf) and Shaoguan (Udult) cities in China at the depth of 0–20 cm and amended with biochars at the rate of 3% w/w. After mixing the soil with biochar for 14 days, the Chinese cabbage was planted in the amended soils. Then, it was harvested on the 48th day after sowing period. In Udult soil, Chinese cabbage died 18 days after sowing period in control and soils amended with cinnamomum and mulberry biochars. Although only plants grown with the garden waste biochar treatment survived in Udult soil, amendment of garden waste or mulberry biochars at 3% w/w (450 °C) to Udult soil significantly increased (4.95–6.25) soil pH compared to other biochar treatments. In Udept and Ustalf soils, the application of garden waste and mulberry biochars significantly improved plant biomass compared to control, albeit it was dependent on both biochar and soil properties. Garden waste biochar significantly decreased soil Cd phytoavailable concentration by 26% in the Udult soil, while a decrease of soil Cd phytoavailable concentration by 16% and 9% was observed in Ustalf and Udept soils, respectively. The available phosphorus in biochar and soil pH were important factors controlling toxic metal phytouptake by the plant. Thus, the amendment of soil with biochar at 3% can effectively reduce the mobility of Cd and Pb in soil and plant uptake. However, biochar and soil properties should be well-known before being used for soil toxic metal immobilization.
