Studies on elemental levels in frequently consumed local edibles in any region with a localized disease are meaningful. The present study has identified the levels of 24 elements in nine (6 cultivated and 3 wild) frequently consumed local leafy vegetables from three chronic kidney disease prevalent villages (a total 27samples) using ICP-MS. The comparison of obtained levels of these elements with WHO/FAO permissible values reveals the levels of Ba in all the tested samples, Pb in 15 samples is in excess, whereas Fe and Zn levels are below the required levels, and the other elements are in the permissible levels. Among the 27 tested samples, a high level of Ba was found in Allium cepa of L3, and Pb was in Amaranthus viridis of L2. Among the leafy vegetables Allium cepa from L3 and Amaranthus viridis from L2 showed high levels of Ba and Pb, respectively. In the three locations studied, average Ba and Pb levels are found more in Borivanka (L3) followed by Kusumapuram (L1) and Varaka (L2). Ba levels are excess in both cultivated and wild leafy vegetables, while Pb levels are slightly higher in cultivated than the wild leafy vegetables, which may be due to the usage of chemical pesticides and fertilizers. The present study signifies that frequent consumption of such leafy vegetables may influence the renal functioning in this area, along with other factors like drinking water, other edibles. [Display omitted] •Study area is one of the three Chronic Kidney Disease (CKD) prevalent in the World.•Samples are frequently consumed local Leafy Vegetables from each of three locations.•Reports 24 Elemental levels and compared with WHO/FAO values help to know about CKD.•Results reveal Ba is more and Fe, Zn are low in all and Pb is more in 15 samples.•Elemental levels between samples, locations, wild and cultivated are inconsistent.
