Bashkin and Galiulina review vegetable-associated metal exposure assessment and microbial/agronomic risk-management approaches. Chinese and Russian case-study values are secondary reports; they remain traceable to the cited studies and are not counted as new independent occurrence samples.

Tomsk Table 4 preserves 31 crop/metal mean, min, max and dose rows in structured context; Table 5 preserves 11 dose/reference-dose/HQ triplets. Reported combined non-cancer hazard index 1.745 is a historical source-model result.
Methods (brief)
Narrative synthesis of hazard identification, exposure, dose-response, risk characterization and management. Dabaoshan Tables 3/Figure 1 derive from refs 27–28; Tomsk Tables 4–5/Figure 2 derive from ref 46. Discusses Monte Carlo uncertainty modeling and rhizosphere bacteria that may immobilize metals or alter uptake. No new sampling or systematic review search protocol is described.
Implications
Supports exposure-method and remediation literature discovery. Bacterial effects can increase as well as decrease uptake depending on organism, metal and plant; the review does not establish a universal inoculant intervention. Secondary model outputs are not contemporary health or certification thresholds.
Evidence Fitness: EF-3 for narrative/secondary evidence and EF-X for internally impossible Table 4 summary combinations until original studies resolve them. Preserve provenance without double-counting source datasets.
