“…Additionally, substantial fractions of the studied major and trace elements can be accessible to fauna and flora. The single extraction results in this study were consistent with others that are reported previously previous studies [2,8,42,47,48] demonstrating that the proposed single extraction method assisted by ultrasound radiation may be used to assess the amount of available major and trace metals. Compared to other studies reported previously, the use of ultrasound radiation accelerated extraction procedures and proved to be a useful methodology to investigate rapidly the easily extractable metal fractions from soil samples.…”

“…In addition, there was a slightly variation in pH between the top and the bottom soils. The pH plays a vital role in controlling trace metal mobility with most metals (mainly present in free ionic form) being the most mobile in acidic conditions [42]. Metal mobility is also significant at pH level ranging in 6.5-7 or higher due to metal complexation with dissolved organic matter, which consequently becomes soluble at that pH range [43].…”

“…In view of the above, higher extraction of major and trace metals were achieved using deionized water, acetic acid and EDTA suggesting that there is a high possible risk of realizing trace metals into the environmental compartments [2,8,42,47,48]. Additionally, substantial fractions of the studied major and trace elements can be accessible to fauna and flora.…”

Purpose The aim of this study was to evaluate the applicability of ultrasound assisted single extraction and pseudo-total digestion procedures to investigate the bioavailability and mobility of major and trace elements collected from agricultural soil collected in Mzimvubu farmstead area located in Port St Johns, Eastern Cape Province (South Africa). Materials and methods The potential metal availability was assessed using complexing agent (ethylenediaminetetraacetic acid (EDTA)), mild (cacium chloride (CaCl 2 ) and ammonium nitrate (NH 4 NO 3 )), deionized water and acidic (CH 3 COOH) extractants with the assistance of ultrasound to evaluate mobility and bioavailability of metals. The ultrasound radiation was used to assist the single extraction of major and trace metals from agricultural soils as well shortening the extraction time. The pseudo-total metal content in agricultural soils was obtained using pseudo-total digestion employing aqua-regia. Results and discussionThe results obtained using different solvents for single extraction procedures, revealed that higher extraction of Al (256-681 mg kg −1 ), Fe (172-430 mg kg −1 ) and Mn (35-136 mg kg −1 ), was observed compared to other metals. Among the investigated solvents, deionized water, acetic acid and EDTA proved to be the most aggressive extractants. The geoaccumulation index (2-6) and contamination factor (3-6) demonstrated that Fe, Cr, Mn, Co, Cu, Ni, and Zn could pose significant environmental contamination risk. Conclusions Based on the results obtained, it can be concluded that the high levels of some studied metals was due to anthropogenic activities.

“…A significant relationship between soil extractable nutrients and crop response is one of the most important criteria for selecting soil extractants ( Benton‐Jones , 2003). In the last decade, biological availability and chemical extractability with multi‐element extractants have been compared for many nutrients and crops ( da Fonseca et al, 2010; Soriano‐Disla et al., 2010; Gediga et al, 2015; Korzeniowska and Stanislawska‐Glubiak , 2015; Joshi et al, 2017; Seth et al, 2017, 2018; Zhu et al, 2017; Asensio et al, 2018). However, this relationship remains unclear because it depends on plant species and soil characteristics and, moreover, soil nutrient bioavailability has been assessed by comparing crop‐total and soil nutrients extracted at a single temporal point.…”

Background: Chemical methods allowing a single soil extraction followed by multi‐elemental simultaneous measurement by ICP‐OES are increasingly used to predict plant uptake; however, calibration results against crop response are scarce and contradictory.Aims: Our aims were to evaluate the efficacy of five extractants to predict nutrient uptake by a greenhouse wheat crop, as well as the influence of soil properties on nutrient concentrations in soil extracts and wheat plants.Methods: Unlike other calibration studies, we monitored the pre‐seeding to post‐harvesting changes in soil available Ca, K, Mg, Cu, Fe, Mn, Zn, and Al. We extracted 14 acidic soils (C content: 47–114 g kg−1) with two traditional (AA: ammonium acetate; DTPA: diethylenetriamine‐pentaacetic acid) and three multi‐element extractants (AB‐DTPA: ammonium bicarbonate‐DTPA; Mehlich‐3; AA‐DTPA: ammonium acetate‐DTPA).Results: Relationships between bioavailable and chemically extractable elements were strong for K (R2 = 0.776 to R2 = 0.882; p < 0.001) and Zn (R2 = 0.663 to R2 = 0.721; p < 0.001), especially for AB‐DTPA and AA‐DTPA. Multiple regressions including also soil properties can predict wheat‐Ca (Feoxihydroxides, clay and CaAB‐DTPA; R2 = 0.656; p < 0.001) and wheat‐Cu [Aloxihydroxides and either CuAB‐DTPA (R2 = 0.515; p < 0.01) or CuAA‐DTPA (R2 = 0.472; p < 0.01)]. Pre‐seeding to post‐harvesting changes in KAA‐DTPA and KAB‐DTPA were strongly related with K uptake by wheat (R2 = 0.927 and R2 = 0.949, respectively; p < 0.001); similarly, for wheat‐Zn the best relationships were with ZnMehlich‐3 and ZnAA‐DTPA (R2 = 0.654 and R2 = 0.757, respectively; p < 0.001).Conclusion: Consequently, chemical extractants alone can adequately predict K and Zn bio‐availability, and combined with some soil properties can predict wheat uptake of Ca and Cu, but not that of other nutrients.

“…It is essential to separate and recycle biodegradable organic material from the municipal waste stream to establish a sustainable waste management system (Rathore and Sarmah 2021). Of all of the recycling methods, composting of organic waste is recommended due to its environmental and economic benefits (Asensio et al 2018). In emerging countries, composting has appeared as a vital technology to recycle biodegradable waste while generating a useful product for the residential waste generator or the market (Rastogi et al 2020).…”

Lae City (LC) of Morobe Province is the second-largest city in Papua New Guinea. Due to the abundant natural resources it inherits, the resultant urbanization has led to an influx of the human population. This increase in population as a result of industrialization has led to increased municipal solid waste (MSW) accumulation. To address this exigent issue, which affects the nation’s carbon footprint, it is imperative to review socio-economic and geographic factors to establish a feasible approach for managing MSW efficiently and sustainably. In the quest to achieve the same, the present assessment focuses on the 3 core waste management hierarchy systems to support sustainable development for LC by reviewing existing opportunities and challenges associated with the current MSW management system and the associated policies. The result shows that as a sustainable approach to MSW management of LC, a zero-waste campaign for resource recovery engaging all stakeholders can be implemented since the organic content of MSW generated in LC is as high as 70%. Moreover, the dumping of MSW at the dedicated dumpsite site can be minimized if policies are strengthened and the proposed waste avoidance pathway is implemented strictly. In addition to this, to avoid the contamination of groundwater and recovery of methane, the use of the Fukuoka approach in the existing landfills has been suggested to capture leachate without any huge expenditure.
