“…Its pollution is a severe global issue since it can build in agricultural soil and edible sections of crops, and eating those contaminated components can cause cancer in humans [ 12 ]. Its various natural and anthropogenic sources include rock weathering, atmospheric deposition, urbanization, wastewater irrigation, sewage sludge application, the overuse of phosphate fertilization, mining, and smelting-originated Cd contamination in the soil [ 82 ]. Geological parent material decides the background Cd level.…”

“…Geological parent material decides the background Cd level. However, it has generally been reported as being in the range from 0.06–1.1 mg kg −1 with a 0.01 mg kg −1 lower value and 2.7 mg kg −1 higher value [ 82 ]. However, due to human activities, a higher bioavailable Cd level (up to 14 mg kg −1 ) has been reported in several regions of the world [ 11 , 12 ].…”

One of the most concerning global environmental issues is the pollution of agricultural soils by heavy metals (HMs), especially cadmium, which not only affects human health through Cd-containing foods but also impacts the quality of rice. The soil’s nitrification and denitrification processes, coupled with the release of volatile organic compounds by plants, raise substantial concerns. In this review, we summarize the recent literature related to the deleterious effects of Cd on both soil processes related to the N cycle and rice quality, particularly aroma, in different water management practices. Under both continuous flooding (CF) and alternate wetting and drying (AWD) conditions, cadmium has been observed to reduce both the nitrification and denitrification processes. The adverse effects are more pronounced in alternate wetting and drying (AWD) as compared to continuous flooding (CF). Similarly, the alteration in rice aroma is more significant in AWD than in CF. The precise modulation of volatile organic compounds (VOCs) by Cd remains unclear based on the available literature. Nevertheless, HM accumulation is higher in AWD conditions compared to CF, leading to a detrimental impact on volatile organic compounds (VOCs). The literature concludes that AWD practices should be avoided in Cd-contaminated fields to decrease accumulation and maintain the quality of the rice. In the future, rhizospheric engineering and plant biotechnology can be used to decrease the transport of HMs from the soil to the plant’s edible parts.

“…Te long-term use of untreated sewage liquid is linked to an increase in toxic metal accumulation in vegetables, which has serious health consequences [30]. Studies on African leafy and root vegetables have revealed that cadmium and lead levels considerably increase when more contaminated liquid is used to water the plants [31].…”

Lack of nutritive and consumption of polluted food sources are the main health implications in African countries. Vegetable production is an optional balanced food source easily grown in the urban and rural areas. However, the levels of contaminant heavy metals in cultivated vegetables have not yet been identified. This review scrutinizes the contamination route, sources, health effects, environmental problems, food safety complications, and remedial activities of vegetable production in Ethiopian agriculture. Informal settlement, the rapid rate of urbanization, and the lack of community-based industrial expansion lead to massive increases in toxic heavy metals in ecosystems. They are supplied with food source diets unrestrictedly, mainly for vegetable consumption. Among the assessed metals, Zn (112.7 mg/kg), Cr (47.7 mg/kg), Pb (17.76 mg/kg), and Cd (0.25 mg/kg) existed in vegetables, with the highest concentrations in Ethiopia. They have negative effects on public safety, environmental security, and nutrient levels in horticultural crops. Hence, Ethiopia has no permissible standards for vegetable consumption and hazard analysis, critical control point, or food safety system. Additionally, physical, biological, and natural remedial strategies such as phytoremediation, phytoextraction, phytostabilization, rhizofiltration, bioremediation, and phytovolatilization are not applied to curtail deadly substance contents in Ethiopia. Despite this, some mitigation strategies, such as industrial waste treatment activities, are underway in Ethiopia’s universities and beer and sugar factories. This review found that the use of integrated remedial strategies could help to improve the efficiency of strategies in a sustainable manner, solid safety control for heavy metal management in Ethiopia, and management should begin with local solutions.
