“…Leaching of nitrogenous fertilisers and other agrochemicals used in intensive agriculture contaminate groundwater (Gao et al 2012). Agriculture with arsenic and fluoride contaminated water causes pollution in the soil and also affects cultivated crops, posing a serious threat to human health when transferred through the food chain (Baboo et al 2022).…”

Agriculture has played an important role in human life, both for sustaining life and livelihood. The population explosion has necessitated huge agricultural production. Consequently, there has been modernisation of agriculture not only in farming practices, but also in introducing improved agricultural implements, irrigation, chemical fertilisers, synthetic pesticides, and high-yielding seeds. Agricultural intensification and monoculture make it possible to increase crop production, to a large extent gaining food security, but paying no or little attention to environmental well-being. Intensive tillage leads to soil erosion, nutrient loss, and soil organic carbon loss, which affects the soil biota. Extraction of underground water for irrigation causes groundwater levels to drop and hinders aquifer recharge. Monoculture and the cultivation of high-yielding crops lead to the loss of many indigenous crop varieties and the prevalence of pests and pathogens. Extensive chemical fertiliser application can cause soil acidification, eutrophication, and nitrate contamination in groundwater through leaching. Indiscriminate use of pesticides is a potential threat for non-target organisms, including humans. The agriculture sector contributes a considerable portion of greenhouse gases to the atmosphere. Therefore, the only way to protect our mother earth and create a healthy environment is through sustainable agriculture to ensure food safety and security.

“…Te highest levels of Ag in the air cause breathing problems, stomach and esophageal irritation, and pain in the lungs, and Ag chloride molecules might harm the organs, kidneys, eyesight, epidermis, and respiratory system [37]. Arsenic is a natural mineral found inside the subsurface, and it is also spread widely in the surroundings and is exceedingly hazardous in its elemental state [38]. Highly lethal heavy metals have a variety of acute and chronic toxic efects on the environment, as shown in Figure 3.…”

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.

“…Arsenic contamination above the permissible limit (10 μg/L) in the groundwater of north-east India was first reported in 2004. While the problem is significantly higher in of As is believed to be the mountainous rocks (Baboo et al, 2022;Das et al, 2015;Shukla et al, 2019). Generally, As is deposited on the surface soil, and its residence is about 1000-3000 years, especially in moderate temperature and climatic precipitation conditions (Mondal et al, 2006;Tarvainen et al, 2020).…”

“…In Barak Valley, South Assam, a maximum of 350 μg/L of groundwater As has been reported. Successions of alluvial quaternary sediments overlie the region, and the primary source of As is believed to be the mountainous rocks (Baboo et al., 2022; Das et al., 2015; Shukla et al., 2019). Generally, As is deposited on the surface soil, and its residence is about 1000–3000 years, especially in moderate temperature and climatic precipitation conditions (Mondal et al., 2006; Tarvainen et al., 2020).…”

This study investigated the concentrations of arsenic (As) in soil and plant biomass from the Barak Valley in South Assam, India. Soil samples showed concentrations ranging from 6.06 ± 0.84 mg/kg to 18.61 ± 1.52 mg/kg, with an average of 10.60 ± 3.15 mg/kg, 41.67% of the sample exceeding uncontaminated ranges (0.1–10 mg/kg). Ecological risk assessments such as contamination factors, pollutant load index, geo‐accumulation index, and anthropogenicity identified varying contamination levels across sampling points. A total of 24 plant species were collected, ferns (two species), shrubs (five species), grass (six species), and herb (11 species). The concentration of As in different plants types decreased in the order of fern (393.45 ± 159.63 mg/kg) > shrub (20.48 ± 7.25 mg/kg) > herb (17.92 ± 13.75 mg/kg) > grass (14.98 ± 13.80 mg/kg). Plant species, namely Pityrogramma calomelanos, Christella dentata, Mimosa pudica, Chromolaena odorata, Leucas aspera, Persicaria decipiens, Melastoma malabathricum, and Clerodendrum infortunatum, accumulated higher concentrations of As in their above‐ground parts compared to roots and were categorized as tolerant accumulators (TF > 1). By incorporating these plant species into phytoextraction strategies, the region can benefit from their unique properties and abilities to effectively remediate arsenic‐contaminated sites, ultimately improving the affected areas' environmental and human health conditions.
