Designing healthy edible cities: investigating the environmental and spatial factors affecting urban fruit safety

Urban Farm DB summary

This study investigated factors affecting lead and cadmium levels in urban fruits in Tehran's Tarasht neighborhood, Iran, due to heavy traffic and urban gardens. It found that sites taller than 10 meters had the highest cadmium, while sites without barriers or with 4-meter barriers showed the highest lead content. Barrier width, urban fruit tree height (for lead), distance to the street, and fruit type also influenced heavy metal absorption, indicating significant contamination risks.
