“…Because of their toxicity, persistence, and bioaccumulation, heavy metals are among the most dangerous pollutants and may pose a risk to the ecosystem (Nasr et al 2006). The following criteria form the foundation of the idea of the thorough mapping of heavy metals soil pollution: (1) Determining the classes of heavy metal pollution in soil in order to estimate the potential for heavy metal pollution (2) Evaluation of the gradient and aspects of soil pollution caused by heavy metals (Abd-El-Hady and Abdelaty 2022). There are three classes of heavy metals are distinguished: first) transition elements, which include Ti, Zr, Hf, Rf, V, Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Ru, Os, and Zn, among other minor amphoteric oxides; second) components of rare earth like La and Ac; and thrid) components of the p-group that are led by Ga, In, Tl, Sn, Pb, Sb, Bi, and Po (Ameri et al 2020).…”

HIS STUDY targeted the concentrations of heavy metals (iron, manganese, copper, and zinc) in wastewater sources in Kafr El-Sheikh Governorate, Egypt, and proved their presence in different concentrations heavy metals (Fe, Mn, Cu, and Zn) concentrations in wastewater at Kafr El-Sheikh Governorate, Egypt, and proved their existence with different concentrations. Numerous microalgae were found to significantly remediate different heavy metals from wastewater. Within the study's conclusions were the isolation and identification of Pseudoanabaena mucicola under accession OR143298 for the remarkable capability of, chemical oxygen demand (COD), total suspended solid (TSS), total dissolved solid (TDS), biological oxygen demand (BOD) and heavy metals (Fe, Mn, Cu, and Zn) removal from wastewater at 28 ͦ C and different pH (7, 8 and 9) for 1-4 weeks. The decreasing capacity by P. mucicola were 90.03% for chemical oxygen demand (COD), 42.95% total dissolved solid (TDS), 89.88% biological oxygen demand (BOD), and increasing the TSS by 125.83% after 4 weeks. P. mucicola absorbs 100% Fe from wastewater after 3 weeks, Mn from wastewater after 2 weeks, Cu, and Zn from wastewater after 1 week, respectively. The results that were presented showed how promising P. mucicola is for biosorbing heavy metals (Fe, Mn, Cu, and Zn) from wastewater.

“…Shale deposits, rich in clay minerals (Wilson and Wilson, 2014), can be used successfully to improve the characteristics of sandy soils (Eldardiry and Abd El-Hady, 2012;Hassan et al, 2016); yet contaminant founds in these shales should be lessened, prior to their use, to meet the acceptable environmental levels (Khurramovna et al, 2021). Potentially toxic elements are of special concern because these contaminants do not undergo biodegradation (Hashim et al, 2017;Abbas and Bassouny, 2018;Farid et al, 2019); hence possessing long term negative environmental impacts (Abdelhafez et al, 2015;Elshazly et al, 2019;Abdelhafez et al, 2021;Sarhan et al, 2021;Abd-El-Hady and Abdelaty, 2022;Asaad et al, 2022;Hussein et al, 2022;El-Shwarby et al, 2022;Mekawi et al, 2023).…”

Evaluating the removal efficiency of potentially toxic elements (PTEs) from a shale deposit by citric acid

HE MAJORITY of arable lands of Egypt are deserts, mainly sandy soils of low fertility, low water retention and high water and wind erodibility. Shale deposits (rich in clay minerals) might be considered suitable conditioners to improve soil physical, chemical and mineralogical properties and hence increase its productivity. However, these additives should not be a source of contaminants such as PTEs. Accordingly, a technical shale deposit sample was collected fromAbu Thor (longitudes between 33 ○ 22″ and 33 ○ 23ʺ E and latitudes between 29 ○ 00″ and 29 ○ 02ʺ N), Southwest Sinai. In this shale deposit sample, silica comprised 37.35% and alumina was about 18.37%. This sample also contained630 mg Mn, 7704 mg Zn, 19200 mg Fe, 2627 mg Pb, 2763 mg Co and 1310 mg Ni per kg. These levels are not environmentally acceptable in shale deposits when used for soil conditioning. Accordingly, removal or at least reduction in contents of these contaminants in shale deposits should be considered prior to their addition as conditioners to low fertile which exhibit low water holding soils such as the sandy ones. To attain this aim, PVC columns (6.8cm inner diameter× 45cm height) were filled with the shale deposit, washed with citric acid (conc: 10 g L -1 ) at a flow rate of 1 mL per min. with a total volume of 3200 mL per column and the leachate was collected every 100 min to determine its content of PTEs. Cumulative extracted PTEs were calculated versus time and best fitted to the power function kinetic model. This extraction followed the sequence of Ni>Fe>Co>Pb≈Zn>Mn and, in general, the removal efficiencies were low and did not exceed 12% of Ni, 4% of Co, 2.97% of Mn, 2% of Pb and 1% for each of Fe and Zn. It can; therefore, be deduced that citric acid can only chelate the easily bounded forms of PTEs. More researches are needed to investigate the efficiency of citric acid for in-situ long term facilitated phytoextraction of PTEs from shale deposits to attain more acceptable levels

These contaminants accumulate on soil surfaces through successive irrigations (Abdelrazek, 2019;Hegazy et al, 2019;Alnaimy et al, 2021;Abuzaid and Jahin, 2022); get absorbed by plants and concentrated within their edible parts (Hashim et al, 2017;Farid et al, 2020;El-Ramady et al, 2021;Hegab et al, 2021;Sarhan et al, 2021); hence adversely affect crops yieldquantity and quality (Ali et al, 2016;Ibrahim et al, 2016;Abosena et al, 2021;Gavrilescu, 2022).…”

Indust rialization processes in Giza governorate (Egypt) brings various organic and inorganic contaminants to surface and ground waters therein. Arable lands located nearby these industrial activities use such waters for irrigation; nevertheless, the contaminants that may exist in irrigation waters adversely affect soil quality and crop yields. Accordingly, periodic monitoring of water quality in this area has become an obligation to ensure its safe use for irrigation. Eighteen irrigation (canals and drain) water samples were collected from different industrial locations nearby the arable lands across Giza governorate in 2019 for quality evaluation. A control (well water) sample was also collected from this governorate so far away from the industrial zone for data comparison. Generally, the studied locations are located within the arid region and maybe the ground waters there are hydraulically connected. The salinity of the collected waters ranged from medium to high according to the classification of FAO. No sodicity, B or Mg hazards were detected in all water samples. On the other hand, the studied water samples were all classified as very hard water since their values of total hardness (TH) ranged from 154.5-293.5 mg L -1 . Concentrations of Co and Pb in all water samples were below the permissible levels while Cd toxicity was detected in almostall water samples. Ni-hazard was identified in only one location. Besides, soils were sampled from the locations nearby the water resources. The principal component analyses indicate that the abovementioned potentially toxic elements (PTEs) in soil originated from almost one distinct source (weathering of rocks along the river path and not from different industrial origins). Their concentrations were below the permissible levels in all soil locations, in spite of that, almost all soils exhibited low pollution levels with PTEs according to the calculations of pollution load index. Concerning the correlations between the total PTEs contents in soil versus soil characteristics, Cd and Co contents were correlated significantly and positively with the CaCO 3 content in soils while Pb was significantly correlated with soil organic matter, and Ni with soil pH. In conclusion, the discharges of the factories in the industrial zone of Giza should be monitored periodically to avoid further negative environmental consequences on the surroundings. Also, there is an intensive need to remediate contaminated wastewater prior to their discharges to the surrounding environment.
