“…Despite the availability of epidemiological studies providing estimations of human health risks arising mainly from water reuse in landscape recreational recharge, viral risks have been largely neglected in criteria establishment, except for a few promulgated criteria defining requirements for systematic viral monitoring [ 35 ]. Furthermore, most approaches regulating the use of reclaimed water through water quality parameter thresholds are flawed in terms of technical guidance [ 42 ]. To alleviate this, we attempted to formulate standards for the level of treatment of viruses in wastewater, considering a new human health-oriented perspective using the reverse QMRA approach [ 43 ].…”

“…Municipal and industrial wastewater are an important source of HM that contaminate rivers and thus irrigation water for neighboring crops. Zhao et al (2022) classified municipal wastewater as the primary source of wastewater employed directly in vegetable crops. The use of treated or untreated wastewater for irrigation to relieve the deficit of freshwater resources has been very common in developing countries (Aftab et al, 2023;Ruan et al, 2023;Yahaya et al, 2023).…”

The growth in urbanization and industrialization is causing an increase in environmental pollution in cities and their surrounding areas. Additionally, the growing urban population requires a greater volume of fresh vegetables. In nature, heavy metals (HM) are widely distributed; when they gradually enter the soil-plant-consumer continuum, they are difficult to remove from the system and accumulate at toxic levels. To gain an overview of this situation, the information in the ScienceDirect database was used in accordance with the PRISMA guide. For this, the keywords “vegetable”, “contamination” and “urban” were used in a first step and, in a second step, the keywords “vegetable” and “heavy metal” were used. The most toxic HM for consumers are Cd, Pb, Hg, Cr and As, as well as essential MP for the plant (Zn, Cu, Ni, Fe, Mo). At excessive concentrations these cause neurological and kidney damage, cancer and other forms of damage to health. Crop contamination can come from the atmosphere, irrigation water, and/or the soil itself, proximity to busy roads, industry, polluted rivers, and excessive use of pesticides and fertilizers that contain HM. Plant poisoning by HM causes a decrease in root growth and biomass of the plant, foliar chlorosis, and other physiological alterations. Leafy vegetables (including aromatic herbs) and solanaceous vegetables accumulate the most HM, while cucurbits and legumes are the least affected. Plants that develop for a longer time accumulate a greater amount of HM. In general, to increase the food safety of urban horticulture, more studies are needed on HM contamination, soil aptitude, risk assessment for ingesting intoxicated vegetables, as well as appropriate instructions for the clean handling of these crops in cities and surrounding areas.

“…On the other hand, irrigation water quality is another remarkable parameter that must be considered during the expansion of wheat crop production. As a result of water scarcity due to climate change and rapid population growth, low-quality water and treated wastewater have been used to irrigate crops in many countries [ 3 , 12 ]. According to the World Health Organization report (2006), more than 10% of the world’s population consumes food irrigated by wastewater [ 12 ].…”

Background One of the current challenges is to secure wheat crop production to meet the increasing global food demand and to face the increase in its purchasing power. Therefore, the current study aimed to exploit a new synthesized nanocomposite to enhance wheat growth under both normal and drought regime. The effectiveness of this nanocomposite in improving the microbiological quality of irrigation water and inhibiting the snail’s growth was also assessed. Results Upon the employed one-step synthesis process, a spherical Fe/Cu/P nanocomposite was obtained with a mean particle size of 4.35 ± 1.524 nm. Cu2+, Fe2+, and P4+ were detected in the dried nanocomposite at 14.533 ± 0.176, 5.200 ± 0.208, and 34.167 ± 0.203 mg/ml concentration, respectively. This nanocomposite was found to exert antibacterial activity against Escherichia coli and Salmonella typhi. It caused good inhibition percent against Fusarium oxysporum (43.5 ± 1.47%) and reduced both its germination rate and germination efficiency. The lethal concentration 50 (LC50) of this nanocomposite against Lanistes carinatus snails was 76 ppm. The treated snails showed disturbance in their feeding habit and reached the prevention state. Significant histological changes were observed in snail digestive tract and male and female gonads. Drought stress on wheat’s growth was mitigated in response to 100 and 300 ppm treatments. An increase in all assessed growth parameters was reported, mainly in the case of 100 ppm treatment under both standard and drought regimes. Compared to control plants, this stimulative effect was accompanied by a 2.12-fold rise in mitotic index and a 3.2-fold increase in total chromosomal abnormalities. Conclusion The finding of the current study could be employed to mitigate the effect of drought stress on wheat growth and to enhance the microbiological quality of irrigation water. This is due to the increased efficacy of the newly synthesized Fe/Cu/P nanocomposite against bacteria, fungi, and snails. This methodology exhibits potential for promoting sustainable wheat growth and water resource conservation.
