Abstract The contamination of edible vegetables with heavy metals is a significant global environmental and public health issue. These inorganic pollutants persist in the environment, accumulate human tissues, pose serious risks. This study aimed to assess levels such as aluminium (Al), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), selenium (Se), zinc (Zn) leaves Brassica oleracea, Hibiscus sabdariffa L., Amaranthus sp., Ipomoea batatas leaves. samples were collected from urban markets Kinshasa Lubumbashi, two major cities Democratic Republic Congo. microwave digestion system was used extract samples, concentrations measured using advanced spectroscopic techniques. detected concentration ranges (in mg/kg dry weight) follows: Pb (0.23–1.76), Cd (0.31–1.73), As (1.16–7.19), Fe (22.69–94.22), Zn (17.75-375.01), Al (18.78–93.62), Cr (0.15–0.77), Cu (1.88–16.17), Mn (7.03-153.89), Se (0.51–3.17). risk assessments revealed non-carcinogenic carcinogenic risks local populations, particularly exposure. findings highlight urgent need for regulatory measures reduce metal exposure consuming areas, aligning sustainability goals.

Soil environmental protection has become a pressing issue for sustainable development. This study collected 153 topsoil samples from typical agricultural area to evaluate the contamination characteristics of heavy metal(loid)s (HMs), identify their potential sources, and assess associated ecological human health risks. The results showed that mean concentration HMs was in order Zn > Cr Ni Pb Cu As Cd Hg; all were below background levels, except Cd. geo-accumulation index (Igeo) improved Nemerow (INI) revealed overall pollution level considered as no or slight contamination, while posed low risk according hazard factor (Ei) (PERI). In addition, three main sources identified through positive matrix factorization (PMF) model: natural source (48.2%; contributed As, Ni, Cu, Pb, Zn), coal burning waste disposal (24%; Hg Cd), activities (27.8%; Cr). (HHR) assessment model Monte Carlo simulation applied risks, suggested children faced higher risks than adults, with 45.83% exceeding non-carcinogenic acceptable limit. contributors carcinogenic respectively. findings local management development agriculture.
