Most underlying mechanisms remain hypothetical. The generalizability of these findings to other tree species and soil conditions remains to be verified. Incompletely composted materials pose risks of pathogen and heavy metal contamination. Long-term application of swine manure may lead to cadmium and zinc accumulation.

Heavy metal contamination in soil systems is an escalating global crisis, yet over 55% of urban agriculture literature focuses on high-tech indoor vertical farming, leaving vulnerable open-field tropical urban agriculture (UPA) severely under-researched.

High concentrations of zinc can cause growth inhibition and oxidative stress. Zinc contamination in soil is a significant environmental hazard. There is a need to develop strategies for safe utilization of zinc-contaminated soils.

There is a lack of systematic assessments of heavy metal contamination in both soils and crops from mining-affected regions. There is a need to consider population-specific dietary risks in food safety assessments.
