“…Compared with natural waters, marginal-quality waters contain a higher load of toxicants that may cause potential risks [1,5]. Metals are the most hazardous inorganic pollutants in soils, including essential (Fe, Mn, Zn, and Cu) and nonessential (Cd and Pb) elements for biological functions [6].…”

Lack of active sorption sites in sandy soils renders metals added by irrigation water more labile and increases their soil-to-plant transfer. Thus, this study investigated the long-term impacts of irrigation using sewage effluents and contaminated groundwater on metal accumulations in TypicTorripsamment soils, and edible parts of food crops. Nine sites in El-Gabal El-Asfar farm, south-eastern to the Nile Delta of Egypt, were selected. At each site, irrigation water, soil (0–30 cm), and the crop’s edible part were sampled in triplicates and analyzed for Mn, Pb, and Zn. Results revealed significant (p < 0.05) differences in metal concentrations among water sources. Thus, constant irrigation caused significant spatial variations in total and available metal contents in soils. Total contents of Pb (in four sites) and Zn (in all sites) exceed the lithosphere range, while the available contents of the three metals exceeded the safe limits in all soils. The index of geo-accumulation indicated no Mn pollution but showed elevated pollution risks for Pb and Zn. The three metals showed high availability ratios, proving the effect of light soil texture. The multivariate statistical analysis indicated that Mn and Zn had similar geochemical behaviors in soils. Metal contents in all crop’s edible parts surpassed the safe limits. The bioaccumulation factor (BAF) was less than 1.0 for Mn and Zn but higher than 1.0 for Pb. The highest BAFs occurred in cabbage leaves, indicating the phytoextraction potential of this species. Sufficient water treatment and proper remediation techniques are recommended to alleviate metal accumulation in food crops and their transfer via the food chain.

“…The use of wastewater raises, however, sanitary problems and risk both for farmers and crops and problems of agronomic nature due to the presence of biotic and abiotic toxic substances [5]. Wastewater irrigation is one of the principal contributing pathways for environmental metal pollution, especially in arid regions [6], where this practice has become necessary to compensate for freshwater scarcity coupled with limited rainfall [7]. In Egypt, recycling of treated sewage effluents in irrigation has been initiated since 1911 in a small farm (1250 ha) in the eastern desert [8], and extended to large-scale pilot projects occupying about 70,000 ha in several desert lands for irrigating trees beside some field crops [9].…”

Accumulation of Potentially Toxic Metals in Egyptian Alluvial Soils, Berseem Clover (Trifolium alexandrinum L.), and Groundwater after Long-Term Wastewater Irrigation

et al. 2021

The reduced availability of water resources in Egypt has imposed the need to intensify the use of wastewater for crop irrigation in the alluvial soils of anthropogenic origin. Relevant effects can derive from contents of potentially toxic metals (PTMs) in supply resources soils, crops, and groundwater in these areas. For this reason the PTM content has to be monitored to evaluate and minimize health hazards. Therefore, in this context, two areas of the SE Nile Delta subjected to 25 year of wastewater irrigation, using agricultural drainage water (ADW) and mixed wastewater (MWW) were chosen and compared with a nearby site irrigated with Nile freshwater (NFW). At each of the three sites, ten samples of irrigation water, topsoil, berseem clover (Trifolium alexandrinum L.) plants, and seven groundwater samples were collected and analyzed for Cr, Co, Cu, Pb, Ni, and Zn. Results indicate that the total contents of Co, Cu, Ni, and Zn in soils collected from the three sampling sites and Pb in the MWW-irrigated soils were higher than their average natural contents in the earth’s crust, indicating potential risks. The DTPA-extractable contents of Cu in the three sites, in addition to Pb and Zn in the MWW-irrigated soils, exceeded the safe limits. The MWW-irrigated soils showed a considerable degree of metal contamination, while the NFW- and ADW-irrigated soils showed moderate and low levels of contamination, respectively. The contents of the six PTMs in the three sites showed low individual ecological risks, except for Pb in the MWW-irrigated soils that showed a moderate risk; however, the overall ecological risk remained low in all samples. The values of Co, Cu, and Ni in berseem shoot in addition to Pb from the MWW-irrigated soils were over the maximum permissible levels for animal feeding. Values of root-to-shoot translocation factor were lower than 1.0 for Cr, Co and Ni but higher than 1.0 for Cu, Pb, and Zn. Berssem plant is a good candidate for phytofiltration of Cr, Co and Ni, while for extracting Cu, Pb and Zn from polluted soils. The groundwater samples collected from the three sampling sites showed lower metal concentrations than the safe limits for drinking standards. Further remediation studies should be taken into account to alleviate potential environmental and health-related risks when using supply resources different from freshwater.

“…The allowed limit of the treated wastewater's Sodium Adsorption Ratio (SAR) for irrigation is around 9 mg L −1 . (Abbas et al 2020) The recorded results obtained for the hemodialysis wastewater were significantly greater than the acceptable limits in the FAO / WHO guidelines (Figs. 4D and 6C).…”

“…These effects can be remedied and reduce the drug burden and risks to wastewater treatment plants through separate treatment of wastewater in hospitals (Verlicchi et al 2012 ;Orias and Perrodin 2013). The study was based on FA / WHO standards and the Egyptian Code of Practice (ECP 501/2015) for wastewater use in agriculture and irrigation Pescod, 1992;Carr et al 2004;Abbas et al 2020). It is important to remember that sophisticated reverse osmosis systems reduce losses, which aids in the elimination of water waste.…”

Hemodialysis water is an essential element necessary for the production of dialysates as well as disinfection generators. Each patient's hemodialysis session requires around 120 liters of filtered water. Assiut University Hospitals' hemodialysis facilities treat more than 300 patients each day and perform over 85,000 hemodialysis sessions per year. This study includes an evaluation of the bacteriological and physicochemical quality of blood dialysis waste and water rejected from the treatment units. Samples were collected and tested in accordance with standard methods of wastewater analysis. The physicochemical investigation focused on the extent of potential hydrogen (pH), electrical conductivity (EC), chemical oxygen demand (COD), biochemical oxygen demand (BOD), chloride, and total dissolved solids (TDS), as well as Magnesium (Mg), Potassium (K), Calcium (Ca2), Nitrogen (N), Phosphorus (P), Sodium (Na), Chloride (Cl), Bicarbonate (HCO3), Oil & Grease, total phenol. Also, enumeration of fecal coliforms was performed by membrane filtration and searches for Streptococci sp. and Pseudomonas aeruginosa were conducted through microbiological investigation. According to the findings, untreated effluents cannot be used directly for irrigation. Prior treatment is required to improve the quality of the wastewater. The results for the heavy metals Lead (Pb), Mercury (Hg), Iron (Fe), Cobalt (Co), Silver (Ag), Nickel (Ni), Cadmium (C), and Manganese (M) revealed compliance with acceptable norms. It would be beneficial to investigate the possibility of recycling effluent from Assiut University Hospital's hemodialysis center. Which leads to saving water resources and protecting the environment? It is critical to investigate the possibility of reusing or recycling it. This work brings attention to this neglected subject, particularly in hemodialysis therapy, by evaluating the feasibility of hemodialysis wastewater reuse.
