Investigation of Heavy Metals in the Urban Agricultural Soils Near Railway and Industrial Complex in Jinju, Gyeongsangnam-do

Urban Farm DB summary

This study investigated heavy metal contamination in urban agricultural soils near railway tracks and an industrial complex in Jinju, South Korea, to ensure food safety. While the average heavy metal values did not exceed soil contamination guidelines, some individual soil samples showed concentrations higher than the guidelines. Furthermore, the geoaccumulation index (Igeo) indicated that several soils were contaminated compared to background levels, with Cu, Pb, Zn, and Sb showing the highest contamination. Long-term monitoring of urban vegetable garden soils is recommended.
