Although the cultivation of food crops in farmland heavily contaminated by heavy metals is prohibited China, vegetables can still be planted on a small-scale due to their short growth cycles and flexible sale models, posing significant threat local consumers. In this study, pot culture experiment was conducted investigate feasibility safe production through in-situ stabilization soil. The remediation efficiency wheat straw biochar N-doped biochar, spinach, metal accumulation potential health risks were also explored. results indicated that both significantly affected soil pH, cation exchange capacity, organic matter, available phosphorus, potassium, alkaline nitrogen content, spinach biomass, but trends variable. Additionally, diethylenetriaminepentaacetic-extractable Pb, Cd, Cu, Zn, Ni concentrations decreased 9.23%, 7.54%, 5.95, 7.44%, 16.33% with 10.46%, 12.91%, 21.98%, 12.62%, 12.24% respectively. Furthermore, reduced 35.50%, 33.25%, 30.31%, Health risk assessment revealed non-carcinogenic index for adults children from 17.0 54.8 16.3 52.5 11.8 38.2 respectively, remained higher than acceptable range (1.0). carcinogenic posed Cd exceeded value (10−4) across all treatments. These may imply cannot achieve stabilization.
