“…But the worst part is that it might carry significant amounts of toxic heavy metals that contaminate vegetables and other edible agrofoods [5,26,29]. However, several sources of elements or components, such as climate change, unwanted seasonal variation, excessive use of fertilizer and pesticides, industrial effluent, electronic waste, man-made waste, and poor management of agricultural land [30][31][32][33][34] that influence or hamper the balance of the nutrient cycle, affect overall soil health and plant nutrients [15].…”

The consequences of climate change, food security, and self-sufficiency goals are driving excessive human activity onto vegetable farms in Bangladesh, and harmful heavy metal exposure is spreading. So, the study assessed the toxic metals (Pb, Cd, and Cr) exposure, characteristics, and human health risk regarding the soil-vegetable system of two distinct locations in Bangladesh using atomic absorption spectrometry. The average concentration of metals in soil and fertilizer/pesticide samples followed the same order (Cr > Pb > Cd), but for vegetable samples, the order was Pb > Cr > Cd, with some extra Pb compared to the World Health Organization (WHO) allowable limit (0.3 mg/kg). Low levels of pollution with negligible ecological concerns were predicted for both locations by the soil quality indexing. But industrial influence boosted the Pb content in location B, and common sources (fertilizer/pesticide) for both locations might be responsible for a moderate level of Cd. The toxic metals transferred to vegetables followed the trend of Cd > Pb > Cr. However, the human health risks arising from harmful metals exposure at both locations were ineffective (< 1) in evaluating noncarcinogenic risk patterns through the target hazard quotient (THQ), total THQ, and hazard index (HI). Again, considering probable carcinogenic risk patterns, vegetable consumption with studied exposure levels of toxic metals followed within the acceptable range (between 1.0E-04 and 1.0E-06). Overall, location B is slightly more vulnerable than location A by considering metal exposure, pollution distribution, and risk evaluation in the study area (significant at p < 0.05). So, systematic monitoring and protective measures are required to ensure food safety and sustainable vegetable production.

Climate changes effects, food security and self-sufficiency targets in densely populated countries like Bangladesh forced excessive human activities on vegetable farmland, and heavy metal contamination may result. An analysis of three toxic heavy metals, such as lead (Pb), cadmium (Cd), and chromium (Cr), was conducted to determine their source and associated health risks in vegetables, taking into account source pathways, fertilizers/pesticides and soil, using 12 sampling points at two different locations in two different Flam-Atomic Absorption Spectrometry (F-AAS) and Graphite Furnace-AAS (GF-AAS) modes. In soil and fertilizers/pesticides, the mean concentration of heavy metals declined in the same order of Cr > Pb > Cd. For vegetables, the mean concentration decreased in the order of Pb > Cr > Cd with some extra quantity of Pb compared with an allowable limit of World Health Organization (WHO) predicting industrial and fertilizer usage impact on location B. For both locations, the quality indexing of soil projected low levels of contamination with insignificant ecological risks. The toxic metal transfer to vegetables followed the order Cd > Pb > Cr, the same for both locations but higher at location B. However, the toxic metals uptake through vegetables was much less than maximum tolerable daily intake. The human health risks arising from harmful metals exposure at both locations were ineffective (< 1) in evaluating non-carcinogenic risk patterns through target hazard quotient (THQ), total THQ and hazard index (HI). Again considering probable carcinogenic risk patterns, vegetable consumption with studied exposure levels of toxic metals will be significant (between 1.0E-04 to 1.0E-04). Overall, location B is a little bit more vulnerable than A by considering the non-carcinogenic and carcinogenic model and related intervention and protective measures are needed to be taken.
