“…This observation corroborated the study of Hacioglu and Tosunoglu [ 38 ] in which high resistance of heavy metal-resistant bacteria isolated from an aquatic species at Kavak Delta to similar antibiotics was observed. Similarly, Omotayo et al [ 39 ] reported that the heavy metal-resistant bacteria isolated from wastewater treatment plant exhibited resistance to two or more classes of antibiotics.…”

The indiscriminate deposition of metal-containing substances into the environment contributes significantly to high concentrations of metals in the soil resulting in resistance to metals and consequentially to antibiotics by inherent microbes which may eventually spread to other pathogenic microbes thereby elevating disease burden due to antibiotic resistance. The study aimed at determining the co-occurrence of resistance of bacteria isolated from metal-contaminated soil to heavy metals and subsequently, antibiotics. Metal-tolerant bacteria were randomly isolated from top soils from a battery waste site using the pour plate method. Selected isolates were identified using biochemical tests, then, subjected to elevating supplemented concentrations of different metal salts at 100-500 μg/mL to determine the minimum inhibitory concentration. Isolates tolerant to minimum three metals up to 400 μg/mL were subjected to Sulfamethoxazole-trimethoprim (25 μg), Imipenem (10 μg), Amoxicillin (30 μg), Ciprofloxacin (10 μg) and Tigecycline (15 μg) and observations interpreted using the guiding principle of the Clinical and Laboratory Standards Institute. Metal concentrations in the soils exceeded permissible limits. In total, 16 isolates were selected and identified as Proteus sp. (1), Pseudomonas spp. (5), Enterobacter spp. (2), Klebsiella spp. (2), Escherichia spp. (3), Raoultella spp. (2) and Rahnella sp. (1). Thirteen (81.25 %) of all isolates showed multi-resistance to the metals and seven exhibited multidrug-resistance, with 4 (57.1 %) showing resistance to three different classes of antibiotics and 3 (42.9 %) showed resistance to four antibiotic classes. Heavy metal-tolerant bacteria isolated from this study possess co-selection potentials as they showed resistance to different metals and antibiotics classes which is a concern to public health.

Heavy metals are naturally occurring elements with a high atomic weight and a minimum density five times greater than that of water. Many heavy metals are known to be highly toxic and can be absorbed by humans through ingestion, inhalation, or skin contact, leading to various health issues. Children are particularly vulnerable to the health effects of heavy metal exposure compared to adults. The detrimental impact of these elements on children's health encompasses conditions such as intellectual disabilities, neurocognitive impairments, behavioural issues, respiratory ailments, cancer, and cardiovascular disorders. Given their potent toxicity, extensive utilization, and widespread occurrence, heavy metals warrant significant attention. This review thus investigates the pathways of exposure and health ramifications associated with mercury (Hg), lead (Pb), chromium (Cr), cadmium (Cd), and barium (Ba) in children, elucidating their toxic effects. In addition, different treatment methods are being discussed.
