- Observation Workshop A soil had a lower pH than Workshop B soil.
- Observation Workshop A soil had higher organic matter content than Workshop B soil.
- Observation Workshop A soil had elevated Cu concentration of 0.935 mg kg⁻¹ compared with Workshop B.
- Observation Workshop A soil had elevated Cd concentration of 0.251 mg kg⁻¹ compared with Workshop B.
- Observation Workshop A soil had elevated Mn concentration of 29.55 mg kg⁻¹ compared with Workshop B.
- Observation Stem tissues of Amaranthus hybridus showed 1.2–2.1 times greater metal accumulation than leaves.
- Observation Bioconcentration factors remained below 1.0 for most metals in the two vegetables.
- Observation Bioconcentration factors for Ni were anomalously high in Soil B, at 6.5–9.5.
- Observation Target Hazard Quotients and Hazard Index values were below 1.0, indicating acceptable non-carcinogenic risk.
- Observation Total Cancer Risk ranged from 1.65 × 10⁻⁵ to 3.26 × 10⁻⁵, within USEPA acceptable limits.
- Observation Children showed higher vulnerability to the health risks.
- Observation Amaranthus hybridus reached 54.44 cm height in Soil A, superior to Ocimum gratissimum at 45.64 cm.
- Recommendation Continuous monitoring and soil remediation strategies are essential for sustainable urban agriculture in automobile workshop-impacted areas.
